Sonography guided femoral nerve block. Local anesthetic nerve block (local anesthetic regional nerve blockade, or often simply nerve block) is a short- term nerve block involving the injection of local anesthetic as close to the nerve as possible for pain relief. The local anesthetic bathes the nerve and numbs the area of the body that is supplied by that nerve. The goal of the nerve block is to prevent pain by blocking the transmission of pain signals from the surgical site.

|
During pregnancy, it is not common for local anesthetics to have any adverse effect on the fetus. Despite this, risks of toxicity may be higher in pregnancy due to an increase in unbound fraction of local anesthetic and physiological changes increase the transfer of local anesthetic into the central nervous system. Hence, it is recommended that pregnant women use a lower dose of local anesthetic to reduce any potential complications.

Antibiotics may be administered to prevent infection if there is a delay in treatment, if the wound is deep, or if there is a large amount of foreign material in the wound. Pain may be treated with local anesthetic in and around the wound, a regional nerve blockade, or parenteral opiates such as intramuscular pethidine. Local anesthetic may bring almost instant relief for several hours. Vinegar and papain are ineffective.
|
|
Unlike some other opioids and opioid antagonists, buprenorphine binds only weakly to and possesses little if any activity at the sigma receptor. Buprenorphine also blocks voltage-gated sodium channels via the local anesthetic binding site, and this underlies its potent local anesthetic properties. Similarly to various other opioids, buprenorphine has also been found to act as an agonist of the toll-like receptor 4, albeit with very low affinity.

Solutions that have a baricity approaching 1.000 are referred to as isobaric, as the density of the cerebrospinal fluid is approximately 1.0003+/- 0.0003. Solutions with a baricity less than 0.999 are termed hypobaric, and are usually created by mixing the local anesthetic with distilled water. Hyperbaric solutions are created by mixing dextrose 5-8% with the desired local anesthetic. Hyperbaric solutions will flow in the direction of gravity and settle in the most dependent areas of the intrathecal space.

|
Etidocaine, marketed under the trade name Duranest, is a local anesthetic given by injection during surgical procedures and labor and delivery. Etidocaine has a long duration of activity, and the main disadvantage of using during dentistry is increased bleeding during surgery.
|
|
Amide-linked local anesthetic agents, such as lidocaine and bupivacaine, can become "trapped" in their ionized forms on the fetal side of the placenta, so their net transfer across the placenta is increased. An ester-linked local anesthetic agent, such as 2-chloroprocaine, is rapidly metabolized, and placental transfer is limited. Since the metabolism of 2-chloroprocaine by fetal plasma is slower than in maternal plasma, the potential for ion trapping exists. Fetal pH is slightly lower than maternal (7.32 to 7.38), thus most unionized drugs are "ion trapped" to a degree, even in a healthy fetus.

|
During surgeries in and around the eye, such as corneal transplant surgery, the patient often requires injection of a local anesthetic into the eye. In patients who show the photic sneeze reflex, an injection into the eye, such as that undergone in a retrobulbar or peribulbar block, can often elicit a sneeze from the patient. During these procedures, the patient may be sedated prior to the periocular injection. The patient begins to sneeze just as the needle is inserted into the eye, often resulting in the anesthesiologist having to remove the needle before injecting the local anesthetic in order to avoid damaging the patient's eye.
|
|
Cocaine also blocks sodium channels, thereby interfering with the propagation of action potentials; thus, like lignocaine and novocaine, it acts as a local anesthetic. It also functions on the binding sites to the dopamine and serotonin sodium dependent transport area as targets as separate mechanisms from its reuptake of those transporters; unique to its local anesthetic value which makes it in a class of functionality different from both its own derived phenyltropanes analogues which have that removed. In addition to this cocaine has some target binding to the site of the Kappa-opioid receptor as well. Cocaine also causes vasoconstriction, thus reducing bleeding during minor surgical procedures.
|
|
A dental syringe is a syringe for the injection of a local anesthetic. It consists of a breech-loading syringe fitted with a sealed cartridge containing anesthetic solution. In the UK and Ireland, manually operated hand syringes are used to inject Lidocaine in to a patient's gums.

|
Ketamine or morphine may be useful around the time of surgery. Morphine may be helpful for longer periods of time. Evidence for gabapentin is mixed. Perineural catheters that provide local anesthetic agents have poor evidence of success when placed after surgery in an effort to prevent phantom limb pain.
|
|
For some injections, especially deeper injections, a local anesthetic is given. When giving an injection to young children or infants, they may be distracted by giving them a small amount of sweet liquid, such as sugar solution, or be comforted by breastfeeding during the injection, which reduces crying.

|
Benzonatate acts as a local anesthetic and the liquid inside the capsule can be applied in the mouth to numb the oropharynx for awake intubation. However, there can be life-threatening adverse effects when the medication is absorbed by the oral mucosa, including choking, hypersensitivity reactions, and circulatory collapse.
|
|
This may be due to a hypersensitivity reaction to benzonatate or a systemic local anesthetic toxicity, both of which have similar symptoms. There is a potential for these adverse effects to occur at a therapeutic dose, that is, a single capsule, if chewed or sucked on in the mouth.
|
|
Dibucaine, also known as cinchocaine, is an amino amide local anesthetic. When administered to humans intravenously, it is capable of inhibiting the plasma cholinesterase (butyrylcholinesterase) enzyme. The dibucaine number is used to differentiate individuals who have substitution mutations (point mutations) of the enzyme's gene, resulting in decreased enzyme function.

Blockade of the ganglion with local anesthetic, clinically referred to as a ‘sphenopalatine ganglion block’ (SPG) may be performed transcutaneously with a small needle, or topically via the nose with local anesthetic soaked swabs. The topical SPG is used for treatment of persistent migraines and cluster headaches, demonstrating relief within 10-20 minutes. Increasingly the SPG is also used to treat post-dural-puncture headache (PDPH), and may be as effective as an epidural blood patch when used for PDPH. Self-Administration of Sphenopalatine Ganglion Blocks with Cotton-Tipped Catheters with continual capillary feed is the most cost-effective method of treatment and has the benefit of allowing patients to avoid visits to physicians and Emergeny Departments.

In most cases, patients lie on their backs with their knees slightly parted. Occasionally, a patient may also need to have his or her knees raised. This is particularly true when undergoing a Rigid Cystoscopy examination. For flexible cystoscopy procedures the patient is almost always alert and a local anesthetic is applied to reduce discomfort.
|
|
The patient lies face down on the table. The area of the spine that will be treated (lower back, mid back, upper back) is sterilely cleansed with an antibacterial solution using aseptic techniques. The antibacterial solution usually contains iodine and alcohol. A local anesthetic, like Bupivacaine, is injected into the area to numb the joint.

|
Some relief can also be obtained by infiltrating the envenomation site with a local anesthetic. For more extreme cases, an intramuscular injection of a specific horse-derived antivenom can be lifesaving. Tetanus toxoid vaccine should also be administered, if indicated. Surviving victims often suffer localized tissue necrosis and nerve damage, leading to atrophy of adjoining muscle tissues.
|
|
It is also able to inhibit tetradotoxin-facilitated sensitive inward sodium currents in rat superior cervical ganglia. Nisoxetine elicits local (cutaneous) but not systemic analgesia. Compared to lidocaine, a common anesthetic, nisoxetine is more potent (by four folds) and exhibits longer drug action towards producing cutaneous anesthesia. NMDA receptors are not involved in this local anesthetic effect.

|
Usually no treatment is indicated for clinically asymptomatic cervical ectropions. Hormonal therapy may be indicated for symptomatic erosion. If it becomes troublesome to the patient, it can be treated by discontinuing oral contraceptives, cryotherapy treatment, or by using ablation treatment under local anesthetic. Ablation involves using a preheated probe (100 °C) to destroy 3-4 mm of the epithelium.

|
Povidone iodine is equally effective and safe as talc, and may be preferred because of easy availability and low cost. Chemical pleurodesis is a painful procedure, and so patients are often premedicated with a sedative and analgesics. A local anesthetic may be instilled into the pleural space, or an epidural catheter may be placed for anesthesia.

In humans, physiological responses range from dizziness, nausea, vomiting and sleepiness. At large doses, convulsions result, and death usually occurs in extensor spasms. The interaction of dioscorine with the nAChR also results in local anesthetic effects: dioscorine in 0.5% solution has approximately the same activity as 0.05% cocaine. Dioscorine also shows antidiuretic activity and depressant actions.
|
|
The condition is difficult to treat, and may involve fillings, fluoride to fight tooth decay and drugs that increase saliva for dry mouth, as well as oral hygiene instruction. It can be dangerous for active methamphetamine users to undergo dental surgery because of the cardiac problems that can result from the interaction of local anesthetic with the drug.

They are reserved for people with moderate or severe dry eye when other medical treatment has not been adequate. If punctal plugs are effective, thermal or electric cauterization of puncti can be performed. In thermal cauterization, a local anesthetic is used, and then a hot wire is applied. This shrinks the drainage area tissues and causes scarring, which closes the tear duct.
|
|
There is no known cure. The most common approach for mild cases is simply reassurance and topical treatment with calcium-channel blocker (diltiazem, nifedipine) ointment, salbutamol inhalation and topical nitroglycerine. For persistent cases, local anesthetic blocks, clonidine or botulinum toxin injections can be considered. Supportive treatments directed at aggravating factors include high-fiber diet, withdrawal of drugs which have gut effects (e.g.

Kane was convinced that particular surgeries need not involve general anesthesia. He is most well known, both in his own time and today, for demonstrating this by performing self-surgery in 1921 to remove his own appendix under local anesthetic. In 1932 at age 70, he very publicly again performed self-surgery to repair a hernia. Some of Kane’s practices were idiosyncratic.

Angiolipomas are usually easy to remove with surgery, though removal can be complicated with growths in deeper tissue, such as the spine. Corticosteroid injections can shrink or get rid of an angiolipoma by causing the fat cells to shrink and die. This involves injecting a local anesthetic and steroid mixture into the lipoma. Sometimes, a doctor must administer multiple injections.

Clinically the patient may be aware of a snapping or clicking sensation as the ribs move relative to one another. The clinician can reproduce the symptoms by hooking his or her fingers under the costal margin and pulling upwards. Relief can be provided by anesthetizing the relevant intercostal nerve with local anesthetic. If symptoms persist, rib tip resection may be necessary.

|
Local anesthetic agents prevent transmission of nerve impulses without causing unconsciousness. They act by reversibly binding to fast sodium channels from within nerve fibers, thereby preventing sodium from entering the fibres, stabilising the cell membrane and preventing action potential propagation. Each of the local anesthetics have the suffix "–caine" in their names. Local anesthetics can be either ester- or amide-based.

Norcocaine is a minor metabolite of cocaine. It is the only confirmed pharmacologically active metabolite of cocaine, although salicylmethylecgonine is also speculated to be an active metabolite. The local anesthetic potential of norcocaine has been shown to be higher than that of cocaine, however cocaine continues to be more widely used. Norcocaine used for research purposes is typically synthesized from cocaine.

Mepivacaine is a local anesthetic of the amide type. Mepivacaine has a reasonably rapid onset (more rapid than that of procaine) and medium duration of action (shorter than that of procaine) and is marketed under various trade names including Carbocaine and Polocaine. Mepivacaine became available in the United States in the 1960s. Mepivacaine is used in any infiltration and regional anesthesia.

A local anesthetic can reduce the pain. First aid includes immersion of the affected limb in hot water; this is thought to help denature the proteins in the venom. The immobilization of venom at penetration site using a tourniquet or firm constrictive bandaging is no longer recommended. Surviving victims may have nerve damage, which can lead to local muscle atrophy.

This paper analyzed 143 cases reported in to the Royal College of Dental Surgeons of Ontario (RCDSO) over a 21-year period. The results from their analysis seemed to indicate that 4% local anesthetics had a higher incidence of causing paresthesia, an undesirable temporary or permanent complication, after the injection. The authors concluded that “...the overall incidence of paresthesia following local anesthetic administration for non-surgical procedures in dentistry in Ontario is very low, with only 14 cases being reported out of an estimated 11,000,000 injections in 1993. However if paresthesia does occur, the results of this study are consistent with the suggestion that it is significantly more likely to do so if either articaine or prilocaine is used.” In another paper by the same authors,Haas DA, Lennon D. A review of local anesthetic-induced paraesthesia in Ontario in 1994.

Bupivacaine is indicated for local infiltration, peripheral nerve block, sympathetic nerve block, and epidural and caudal blocks. It is sometimes used in combination with epinephrine to prevent systemic absorption and extend the duration of action. The 0.75% (most concentrated) formulation is used in retrobulbar block. It is the most commonly used local anesthetic in epidural anesthesia during labor, as well as in postoperative pain management.
|
|
The most common complications of nerve blocks include bleeding, infection, and block failure. Local anesthetic toxicity, the most dangerous complication, is often first detected by symptoms of numbness and tingling around the mouth, metallic taste, or ringing in the ears. Additionally, it may lead to seizures, arrhythmias, and may progress to cardiac arrest. This reaction may stem from an allergy, excessive dose, or intravascular injection.
|
|
Drugs commonly used for peripheral nerve blocks include lidocaine, ropivacaine, bupivacaine, and mepivacaine. These drugs are often combined with adjuvants (additives) with the end goal of increasing the duration of the analgesia or shortening time of onset. Additives may include epinephrine, clonidine, and dexmedetomidine. Vasoconstriction caused by local anesthetic may be further enhanced synergistically with the addition of epinephrine, the most widely used additive.

Deep brain stimulation is a surgical technique used to alleviate patients from phantom limb pain. Prior to surgery, patients undergo functional brain imaging techniques such as PET scans and functional MRI to determine an appropriate trajectory of where pain is originating. Surgery is then carried out under local anesthetic, because patient feedback during the operation is needed. In the study conducted by Bittar et al.

Using a procedure that was common in the 1930s, he examined epileptic patients who were undergoing brain surgery. These patients were given a local anesthetic, their skulls were opened, and their brains exposed. Then, electrical stimulation was applied to the surface of the brain to map out the speech areas. In this way, the surgeon would be able to avoid any damage to speech circuitry.

Oxetacaine (INN, also known as oxethazaine) is a potent local anesthetic. It is administered orally (usually in combination with an antacid) for the relief of pain associated with peptic ulcer disease or esophagitis. It is also used topically in the management of hemorrhoid pain. Oral oxetacaine preparations are available in several countries, including India, South Africa, Japan, Taiwan and Brazil, but not the United States.

The receptor site is thought to be located at the cytoplasmic (inner) portion of the sodium channel. Local anesthetic drugs bind more readily to sodium channels in an activated state, thus onset of neuronal blockade is faster in rapidly firing neurons. This is referred to as state- dependent blockade. LAs are weak bases and are usually formulated as the hydrochloride salt to render them water-soluble.

The medial septum plays a role in the generation of theta waves in the brain. In an experiment, it has been proposed that the generation of theta oscillations involves an ascending pathway leading from the brainstem to hypothalamus to medial septum to hippocampus. The same experiment demonstrated that injection of lidocaine, a local anesthetic, inhibits theta oscillations from the medial septum projecting to the hippocampus.

A local anesthetic is administered into the wound with a specially designed, multi-holed catheter. The catheter allows for even spread throughout the entire area of the wound, depending on the size of the catheter. The surgeon places the catheter during surgery shortly before closing the surgical incision. For best catheter placement and nerve blockage, the catheter must be located as close as possible to the nerve.

The insertion of a central Groshong line is usually done under local anesthetic by an interventional anaesthesiologist, interventional radiologist or surgeon. Throughout the procedure, ultrasound and X-rays may be used to confirm placement. When a central venous catheter is inserted, a chest radiologic examination is usually performed to confirm the position of the catheter and absence of pneumothorax. The chest radiologic examination is integral to the procedure.
|
|
Thermal burns usually result from placing hot food or beverages in the mouth. This may occur in those who eat or drink before a local anesthetic has worn off. The normal painful sensation is absent and a burn may occur. Microwave ovens sometimes produce food which is cold externally and very hot internally, and this has led to a rise in the frequency of intra-oral thermal burns.

|
Transurethral microwave thermotherapy is a non-surgical, minimally invasive therapy that can be performed under a local anesthetic on an outpatient basis. The treatment involves inserting a special microwave urinary catheter into the hyperplastic prostatic urethra. The microwave antenna within the catheter then emits microwaves to heat and destroy the surrounding prostatic tissue. The procedure can take from 30 minutes to one hour and is well tolerated by patients.

Cavernous nerves from the uterovaginal plexus supply the erectile tissue of the clitoris. These are joined underneath the pubic arch by the dorsal nerve of the clitoris. The pudendal nerve enters the pelvis through the lesser sciatic foramen and continues medial to the internal pudendal artery. The point where the nerve circles the ischial spine is the location where a pudendal block of local anesthetic can be administered to inhibit sensation to the vulva.

It is sometimes called chronic peripheral venous insufficiency and should not be confused with post- thrombotic syndrome in which the deep veins have been damaged by previous deep vein thrombosis. Most cases of CVI can be improved with treatments to the superficial venous system or stenting the deep system. Varicose veins for example can now be treated by local anesthetic endovenous surgery. Rates of CVI are higher in women than in men.

Epinephrine infusions are less vasoconstrictive than norepinephrine as they primarily stimulate β receptor more than α receptors, but the effect remains dose-dependent. Phentolamine also has diagnostic and therapeutic roles in complex regional pain syndrome (reflex sympathetic dystrophy). Phentolamine is marketed in the dental field as a local anesthetic reversal agent. Branded as OraVerse, it is a phentolamine mesylate injection designed to reverse the local vasoconstrictor properties used in many local anesthetics to prolong anesthesia.

The operation requires a general anesthetic (unconscious and pain free) or a local anesthetic (pain free). The surgeon makes an incision around an inch long in the neck just under the larynx (Adam's apple), and locates the offending parathyroid glands. Preoperative testing using sestamibi scanning can help identify the location of glands. It can also be used to limit the extent of surgical exploration when used in conjunction with intraoperative PTH hormone monitoring.

Mohs' technique was later modified by Perry Robins in the 1970s, using fresh-tissue frozen histology. Rather than using the anesthetic Mohs paste, local anesthetic is used. The fresh skin specimen is then mounted on a cryostat, and frozen sections are examined instead of the Mohs paste-fixed sections. This method is now commonly referred to as Mohs surgery, and occasionally chemosurgery, in reference to the Mohs paste that Mohs initially used.

It has been employed by both many indigenous groups in North, Central, and South America for a variety of uses. Called toloache today in Mexico, datura species were used among the Aztec for medicine, divination, and malevolent purposes. For healing, tlapatl was made into an ointment which was spread over infected areas to cure gout, as well as applied as a local anesthetic. The plants were also utilized to cause harm to others.

The pudendal block gets its name because a local anesthetic, such as lidocaine or chloroprocaine, is injected into the pudendal canal where the pudendal nerve is located. This allows quick pain relief to the perineum, vulva, and vagina. A pudendal block is usually given in the second stage of labor just before delivery of the baby. It relieves pain around the vagina and rectum as the baby comes down the birth canal.

If the patient becomes too sleepy or sedated, he or she makes no more requests. This confers a fail-safe aspect that is lacking in continuous-infusion techniques. If these medications cannot effectively manage the pain, local anesthetic may be directly injected to the nerve in a procedure called a nerve block. In the recovery unit, many vital signs are monitored, including oxygen saturation, heart rhythm and respiration, blood pressure, and core body temperature.

Providing dental treatment to individuals who use methamphetamine can be dangerous, because the potential combination of local anesthetic and methamphetamine can cause serious heart problems. There is also an increased risk of serious side effects if opioid medications are used in the patient's treatment. Treatment of meth mouth usually attempts to increase the flow of saliva, halt tooth decay, and encourage behavioral changes. Toothpaste with fluoride is very important to the restoration of dental health.

Nerve blocks may also reduce the risk of developing persistent postoperative pain several months after surgery. Local anesthetic nerve blocks are sterile procedures that can be performed with the help of anatomical landmarks, ultrasound, fluoroscopy (a live X-ray), or CT. Use of any one of these imaging modalities enables the physician to view the placement of the needle. Electrical stimulation can also provide feedback on the proximity of the needle to the target nerve. Interscalene brachial plexus.

A topical anesthetic is a local anesthetic that is used to numb the surface of a body part. They can be used to numb any area of the skin as well as the front of the eyeball, the inside of the nose, ear or throat, the anus and the genital area. Topical anesthetics are available in creams, ointments, aerosols, sprays, lotions, and jellies. Examples include benzocaine, butamben, dibucaine, lidocaine, oxybuprocaine, pramoxine, proxymetacaine (proparacaine), and tetracaine (also named amethocaine).

Cardiac toxicity associated with overdose of intravascular injection of local anesthetic is characterized by hypotension, atrioventricular conduction delay, idioventricular rhythms, and eventual cardiovascular collapse. Although all local anesthetics potentially shorten the myocardial refractory period, bupivacaine blocks the cardiac sodium channels, thereby making it most likely to precipitate malignant arrhythmias. Even levobupivacaine and ropivacaine (single-enantiomer derivatives), developed to ameliorate cardiovascular side effects, still harbor the potential to disrupt cardiac function. Toxicity from anesthetic combinations is additive.

A chordee may be caused by an underlying condition, such as a disorder of sex development or an intersex condition, or from a complication of circumcision, though some medical professionals do not consider it to be true chordee because the corporal bodies are normally formed. However, not all congenital chordee includes abnormal corpora, and case reports of damage to the corpus cavernosum from circumcision are noted in the literature; particularly as a complication of local anesthetic.

The laser ablation of thyroid nodules is performed in day hospital or day-surgery. The patient is placed under mild sedation (the same type of sedation used in an endoscopic examination). A local anesthetic is then applied, and one or two needles (depending on the size of the nodule) placed inside the nodule under ultrasound guidance. Through the lumen of the needles, extremely thin optical fibers are placed, which are connected to a laser light source.

Those with pain but reasonably maintained function are suitable for nonoperative management. This includes medications that provide pain relief such as anti-inflammatory agents, topical pain relievers such as cold packs, and if warranted, subacromial corticosteroid or local anesthetic injection. Topical glyceryl trinitrate appears effective at relieving acute symptoms however, headaches were reported as a side effect. A sling may be offered for short-term comfort, with the understanding that undesirable shoulder stiffness can develop with prolonged immobilization.

|
Early treatment options include pain medication using nonsteroidal anti-inflammatory drugs, and suppression of ovarian function. More advanced treatment includes a minimally invasive procedure performed by an Interventional Radiologist. This minimally invasive procedure involves stopping blood within the pelvic varicose veins using a minimally invasive procedure called a catheter directed embolization. The procedure rarely requires an overnight stay in hospital and is usually performed as an outpatient procedure, and is done using local anesthetic and moderate sedation.

|
The end of a plastic tube is lubricated (local anesthetic, such as 2% xylocaine gel, may be used; in addition, nasal vasoconstrictor and/or anesthetic spray may be applied before the insertion) and inserted into one of the patient's anterior nares. Treatment with 2.0 mg of IV midazolam greatly reduces patient stress. The tube should be directed straight towards the back of the patient as it moves through the nasal cavity and down into the throat.

Local anesthetics were used in Inca civilization where shamans chewed coca leaves and performed operations on the skull while spitting into the wounds they had inflicted to anesthetize. Cocaine was later isolated and became the first effective local anesthetic. It was first used in 1859 by Karl Koller, at the suggestion of Sigmund Freud, in eye surgery in 1884. German surgeon August Bier (1861–1949) was the first to use cocaine for intrathecal anesthesia in 1898.

The perineal approach generally results in less post-operative pain and complications, and a reduced length of hospital stay. These procedures generally carry a higher recurrence rate and poorer functional outcome. The perineal procedures include perineal rectosigmoidectomy and Delorme repair. Elderly, or other medically high-risk patients are usually treated by perineal procedures, as they can be performed under a regional anesthetic, or even local anesthetic with intravenous sedation, thus avoid the risks of a general anesthetic.

|
Similar to other local anesthetics, benzonatate is a potent voltage-gated sodium channel inhibitor. After absorption and circulation to the respiratory tract, benzonatate acts as a local anesthetic, decreasing the sensitivity of vagal afferent fibers and stretch receptors in the bronchi, alveoli, and pleura in the lower airway and lung. This dampens their activity and reduces the cough reflex. Benzonatate also has central antitussive activity on the cough center in central nervous system at the level of the medulla.

Proper anesthesia is essential for ocular surgery. Topical anesthesia is most commonly employed, typically by the instillation of a local anesthetic such as tetracaine or lidocaine. Alternatively, lidocaine and/or longer-acting bupivacaine anesthestic may be injected into the area surrounding (peribulbar block) or behind (retrobulbar block) the eye muscle cone to more fully immobilize the extraocular muscles and minimize pain sensation. A facial nerve block using lidocaine and bupivacaine may occasionally be performed to reduce lid squeezing.

Tincture of benzoin is benzoin resin dissolved in alcohol. This and its numerous derived versions like lait virginal and friar's balsam were highly esteemed in 19th-century European cosmetics and other household purposes; they apparently had antibacterial properties. Today tincture of benzoin is most often used in first aid for small injuries, as it acts as a disinfectant and local anesthetic and seems to promote healing. Benzoin resin and its derivatives are also used as additives in cigarettes.

They are used to remove tartar, treat soft tissues such as gums and to prepare cavities for filling. Of particular interest in the latter instance is the fact that this treatment is so painless that the use of a needle to inject a local anesthetic is usually unnecessary. Laser treatment results in little bleeding, a lower risk of infection and a quicker healing. Another innovation was the use of computer milled ceramic implants for repairing cavities.

Cassaine and the other alkaloids from Erythrophleum were used on many occasions by native Africans to treat a variety of ailments. Some of these ailments were headaches, heart problems, and migraines. Cassaine was also used as a strong local anesthetic, diuretic, and as an antidote for the swallowing of other poisonous substances due to its powerful emetic effects. Prior to and until the 1930s, cassaine and its partner alkaloids were used as local anesthetics in dental and ophthalmic procedures.

Promethazine, a phenothiazine derivative, is structurally different from the neuroleptic phenothiazines, with similar but different effects. It acts primarily as a strong antagonist of the H1 receptor (antihistamine) and a moderate mACh receptor antagonist (anticholinergic), and also has weak to moderate affinity for the 5-HT2A, 5-HT2C, D2, and α1-adrenergic receptors, where it acts as an antagonist at all sites, as well. Another notable use of promethazine is as a local anesthetic, by blockade of sodium channels.

In purer forms, crack rocks appear as off-white nuggets with jagged edges, with a slightly higher density than candle wax. Purer forms of crack resemble a hard plastic in crystalline form, which is brittle. Like cocaine in other forms, crack rock acts as a local anesthetic, numbing the tongue or mouth only where directly placed. Purer forms of crack will sink in water or melt at the edges when near a flame (crack vaporizes at 90 °C, 194 °F).

The lumbar plexus is composed of nerves originating from L1 to L4 spinal roots such as the iliohypogastric, ilioinguinal, genitofemoral, lateral femoral cutaneous, femoral, and obturator nerves. Since the plexus is located deep, there is an increased risk of local anesthetic toxicity, so less toxic anesthetics like chloroprocaine or mepivacaine mixed with ropivacaine are often recommended. A curvilinear ultrasound probe can be used but it is often difficult to see the plexus, so a nerve stimulator is used to locate it.

|
A pacemaker may be implanted whilst a person is awake using local anesthetic to numb the skin with or without sedation, or asleep using a general anesthetic. An antibiotic is usually given to reduce the risk of infection. Pacemakers are generally implanted in the front of the chest in the region of the left or right shoulder. The skin is prepared by clipping or shaving any hair over the implant site before cleaning the skin with a disinfectant such as chlorhexidine.
|
|
Lidocaine was also added as a local anesthetic. Fournier also advocated using compression after the operation, and travelled and lectured to spread the technique. The Europeans had performed the procedures under general anesthesia; in the 1980s American dermatologists pioneered techniques allowing only local anesthetics to be used. Jeffrey Klein published a method that became known as "tumescent" in which a large volume of very dilute lidocaine, along with epinephrine to help control bleeding via vasoconstriction, and sodium bicarbonate as a buffering agent.

An essential activity of local anesthetics is the blockade of sodium channels. In this way, local anesthetics are able to produce infiltrative cutaneous analgesia, peripheral neural blockades, as well as spinal/epidural anesthesia. Due to nisoxetine's sodium channel blocking effect, it is also possible that it may also have a local anesthetic effect. Nisoxetine is able to suppress the nicotine-evoked increase of hippocampal norepinephrine in a dose-dependent nature through effects on the functioning of the nicotinic acetylcholine receptors.

Both methods use the same level of suction, and so can be considered equivalent in terms of effectiveness and safety.Baird (2001), pp. 4-6. The clinician places a speculum into the vagina and cleanses the cervix then uses a local anesthetic using lidocaine in a paracervical block or intracervical injection into the cervix. The clinician may use instruments called "dilators" to gently open the cervix, or sometimes medically induce cervical dilation with drugs or osmotic dilators administered before the procedure.

Chlorcyclizine (Di-Paralene, Mantadil, Pruresidine, Trihistan) is a first- generation antihistamine of the diphenylmethylpiperazine group marketed in the United States and certain other countries. It is used primarily to treat allergy symptoms such as rhinitis, urticaria, and pruritus, and may also be used as an antiemetic. In addition to its antihistamine effects, chlorcyclizine also has some anticholinergic, antiserotonergic, and local anesthetic properties. It also has been studied as a potential treatment for various flaviviruses like Hepatitis C and Zika Virus.

Most patients tolerate having the stent removed using only a topical anesthetic placed in the urethra. Immediately before the procedure, sterile lubrication containing local anesthetic (lidocaine) is instilled into the urethra. Since no intravenous line is inserted and there is no anesthesia, you do not have to be accompanied by anyone else and you can eat normally before and after the procedure. A ureteric stent may also be retrieved without the use of a cystoscope by means of a magnetic removal system.

|
An image is projected onto a screen in the office so the doctor can examine the nasal passages and sinuses in greater detail. The procedure is not generally painful, but the person can be given a spray decongestant and local anesthetic to minimize discomfort. Attempts have been made to develop scoring systems to determine the severity of nasal polyps. Proposed staging systems take into account the extent of polyps seen on endoscopic exam and the number of sinuses affected on CT imaging.

Sutured wound on the teats of a cow Bite wounds from other animals (and rarely humans) are a common occurrence. Wounds from objects that the animal may step on or run into are also common. Usually these wounds are simple lacerations that can be easily cleaned and sutured, sometimes using a local anesthetic. Bite wounds, however, involve compressive and tensile forces in addition to shearing forces, and can cause separation of the skin from the underlying tissue and avulsion of underlying muscles.
|
|
A mixture of short and long-acting local anesthetics is used to prolong the duration as well as reduce the onset of the nerve block. Lidocaine is an appropriate short-acting local anesthetic and drugs such as levobupivacaine or ropivacaine are appropriate long-acting local anesthetics. The amount of drugs needed for a patient during shoulder replacement can range from 30 to 50 ml and is calculated based on the patient's characteristics as well as the specific anesthetic technique used.

|
This practice began in the United States but slowly trickled through to the United Kingdom, with many Britons opting to travel to the US to have the procedure done. The procedure involves having the participant picking the colour of the nipple tattoo (usually involving a mixture of pigments), and then having a local anesthetic applied. The tattoo device is dipped into the pigment and then applied to the nipple until uniform. The procedure usually takes about 30 to 40 minutes.
|
|
The skin over the area of insertion is first cleansed with antiseptic solution, such as iodine, before sterile drapes are placed around the area. The local anesthetic is injected into the skin and down to the muscle, and after the area is numb a small incision is made in the skin and a passage made through the skin and muscle into the chest. The tube is placed through this passage. If necessary, patients may be given additional analgesics for the procedure.
|
|
As part of clinical decision-making, a simple, minimally invasive, in-office procedure may be performed, the rotator cuff impingement test. A small amount of a local anesthetic and an injectable corticosteroid are injected into the subacromial space to block pain and to provide anti-inflammatory relief. If pain disappears and shoulder function remains good, no further testing is pursued. The test helps to confirm that the pain arises from the shoulder primarily rather than referred from the neck, heart, or gut.

Cocaethylene is largely considered a recreational drug in and of itself, with stimulant, euphoriant, anorectic, sympathomimetic, and local anesthetic properties. The monoamine neurotransmitters serotonin, norepinephrine, and dopamine play important roles in cocaethylene's action in the brain. Cocaethylene increases the levels of serotonergic, noradrenergic, and dopaminergic neurotransmission in the brain by inhibiting the action of the serotonin transporter, norepinephrine transporter, and dopamine transporter. These pharmacological properties make cocaethylene a serotonin- norepinephrine-dopamine reuptake inhibitor (SNDRI; also known as a "triple reuptake inhibitor").
|
|
Benzocaine, sold under the brand name Orajel amongst others, is an ester local anesthetic commonly used as a topical pain reliever or in cough drops. It is the active ingredient in many over-the-counter anesthetic ointments such as products for oral ulcers. It is also combined with antipyrine to form A/B otic drops to relieve ear pain and remove earwax. In the US, products containing benzocaine for oral application are contraindicated in children younger than two years old.
|
|
The risk of complications is decreased when proper aseptic technique is followed, and by the use of the imaging guidance. These complications include an epidural abscess due to infection, temporary increased pain, puncture of the sack containing spinal fluid, excess bleeding, nerve damage, leakage of local anesthetic into the spinal canal, and spondylodiscitis (disc inflammation). Most of the symptoms last 24–48 hours and are usually relieved by a cold compress and NSAIDS. The numbness should wear off in a few hours.

|
Electric currents are set to a level such that they only reach the outermost layers of the skin, thus reducing the problem of scarring. Approximately 1–3 treatments may be needed to completely remove a mole. Typically, a local anesthetic is applied to the treated skin area before beginning the mole removal procedure. For surgery, many dermatologic and plastic surgeons first use a freezing solution, usually liquid nitrogen, on a raised mole and then shave it away with a scalpel.

His "unified theory" explains the prolonged effects of local anesthetic placed on the stellate ganglion resolving complex regional pain syndrome (CRPS). It also predicts the positive effect of SGB on estrogen depletion, hot flashes, PTSD and other conditions. Lipov has made numerous media appearances relating to his innovations in the treatment of chronic pain. Many have focused on state- of-the-art disk treatments, implantable neuro-stimulators for lower back pain and treatment of back and leg pain after surgery.

For example, Brucine has an index of 11, is thus perceived as intensely more bitter than quinine, and is detected at a much lower solution threshold. The most bitter substance known is the synthetic chemical denatonium, which has an index of 1,000. It is used as an aversive agent (a bitterant) that is added to toxic substances to prevent accidental ingestion. This was discovered in 1958 during research on lignocaine, a local anesthetic, by MacFarlan Smith of Gorgie, Edinburgh, Scotland.

Ciclazindol (WY-23409) is an antidepressant and anorectic drug of the tetracyclic chemical class that was developed in the mid to late 1970s, but was never marketed. It acts as a norepinephrine reuptake inhibitor, and to a lesser extent as a dopamine reuptake inhibitor. Ciclazindol has no effects on the SERT, 5-HT receptors, mACh receptors, or α-adrenergic receptors, and has only weak affinity for the H1 receptor. As suggested by its local anesthetic properties, ciclazindol may also inhibit sodium channels.

August Bier (1861–1949), pioneer of spinal anesthesia In 1855, Friedrich Gaedcke (18281890) became the first to chemically isolate cocaine, the most potent alkaloid of the coca plant. Gaedcke named the compound "erythroxyline". In 1884, Austrian ophthalmologist Karl Koller (18571944) instilled a 2% solution of cocaine into his own eye and tested its effectiveness as a local anesthetic by pricking the eye with needles. His findings were presented a few weeks later at annual conference of the Heidelberg Ophthalmological Society.

If displacement does occur, then the space separating the fragments fills with blood shed by the damaged blood vessels within the bone. This collection, or pool, of blood is known as a hematoma. Injection of a suitable local anesthetic by needle and syringe through the skin into this hematoma produces relief of the pain caused by the fracture, allowing the bones to be painlessly manipulated. Despite its rarity in clinical practice, it has regained popularity amongst some members of the medical community.

The pillar procedure is a minimally invasive treatment for snoring and obstructive sleep apnea. In the United States, this procedure was FDA indicated in 2004. During this procedure, three to six+ Dacron (the material used in permanent sutures) strips are inserted into the soft palate, using a modified syringe and local anesthetic. While the procedure was initially approved for the insertion of three "pillars" into the soft palate, it was found that there was a significant dosage response to more pillars, with appropriate candidates.

|
Hence, the reason why this method is considered the gold-standard technique for measuring bone remodelling. Patients undergo double tetracycline labelling, and then samples of bone are collected using trephine under local anesthetic from the iliac crest as it is the only readily accessible site for bone biopsy. This technique is subject to large measurement errors; it is complex and costly to perform and is invasive, meaning that it is painful to the patients. For these reasons, a bone biopsy is not readily acceptable to patients.

Lines of illicit cocaine, used as a recreational stimulant Cocaine is an SNDRI. Cocaine is made from the leaves of the coca shrub, which grows in the mountain regions of South American countries such as Bolivia, Colombia, and Peru. In Europe, North America, and some parts of Asia, the most common form of cocaine is a white crystalline powder. Cocaine is a stimulant but is not normally prescribed therapeutically for its stimulant properties, although it sees clinical use as a local anesthetic, in particular in ophthalmology.

Alcock canal infiltration with corticosteroids is a minimally invasive technique which allows for pain relief and could be tried when physical therapy has failed and before surgery. A long-acting local anesthetic (bupivacaine hydrochloride) and a corticosteroid (e.g. methylprednisolone) are injected to provide immediate pudendal anesthesia. The injections may also bring a long-term response because the anti-inflammatory effects of the steroid and steroid-induced fat necrosis can reduce inflammation in the region around the nerve and decrease pressure on the nerve itself.

|
The use of oral potassium and avoiding high carbohydrate meals can help treat it according to recent tests, following the same approach that is standard for the muscle disease hypokalemic periodic paralysis. Since this condition includes ineffectiveness of the sodium-channel blocker lidocaine, the amide-type local anesthetic used in dental care articaine was tested and found to be effective in one member of the family. No data about other local anesthetics effective in these individuals for non- dental procedures has yet been published.
|
|
During research and development, pramocaine hydrochloride stood out among a series of alkoxy aryl alkamine ethers as an especially good topical local anesthetic agent. Pharmacologic study revealed it to be potent and of low acute and subacute toxicity, well tolerated by most mucous membranes and of a low sensitizing index in humans. Like other local anesthetics, pramocaine decreases the permeability of neuronal membranes to sodium ions, blocking both initiation and conduction of nerve impulses. Depolarization and repolarization of excitable neural membranes is thus inhibited, leading to numbness.
|
|
The antitussive effect of benzonatate begins within 15 to 20 minutes after oral administration and typically lasts between 3 and 8 hours. Benzonatate is hydrolyzed by plasma butyrylcholinesterase (BChE) to the metabolite 4-(butylamino)benzoic acid (BABA) as well as polyethylene glycol monomethyl esters. Like many other local anesthetic esters, the hydrolysis of the parent compound is rapid. There are concerns that those with pseudocholinesterase deficiencies may have an increased sensitivity to benzonatate as this hydrolysis is impaired, leading to increased levels of circulating medication.

|
Because of this, a urinary catheter is often placed for the duration of the epidural infusion. People with continuous epidural infusions of local anesthetic solutions typically ambulate only with assistance, if at all, in order to reduce the likelihood of injury due to a fall. A potential complication of epidural analgesia is the failure to achieve adequate pain control. This can be caused by obesity, multiple prior births, history of opiate use, or cervical dilation of more than 7 cm at the time of administration.
|
|
Before inserting the probe, mild to moderate sedation is induced in the patient to ease the discomfort and to decrease the gag reflex, thus making the ultrasound probe easier to pass into the esophagus. Mild or moderate sedation can be induced with medications such as midazolam (a benzodiazepine with sedating, amnesiac qualities), fentanyl (an opioid), or propofol (a sedative/general anesthetic, depending on dosage). Usually a local anesthetic spray is used for the back of the throat, such a xylocaine and/or a jelly/lubricant anesthetic for the esophagus. Children are anesthetized.

An appreciable tolerance to cocaine's high may develop, with many addicts reporting that they seek but fail to achieve as much pleasure as they did from their first experience. Some users will frequently increase their doses to intensify and prolong the euphoric effects. While tolerance to the high can occur, users might also become more sensitive (drug sensitization) to cocaine's local anesthetic (pain killing) and convulsant (seizure inducing) effects, without increasing the dose taken; this increased sensitivity may explain some deaths occurring after apparent low doses of cocaine.
|
|
Probably the most important discovery in obstetric anesthesia was the introduction of regional anesthesia, in which local anesthetics are used to block pain from a large area (or nerve distribution). Cocaine, the first local anesthetic was used topically in ophthalmology in 1884 by Carl Koller. William Halstead completed the first nerve block; August Bier, the first clinical spinal anesthesia; Sicard and Cathlein, the caudal approach to epidural anesthesia in 1901; and Fidel Pages, the lumbar epidural approach in 1921. In 1921, the first vaginal delivery under spinal analgesia was reported by Kreiss in Germany.

|
Hypokalemic sensory overstimulation is a term coined by MM Segal and colleagues to describe a syndrome of sensory overstimulation, ineffectiveness of the local anesthetic lidocaine, and in females, premenstrual syndrome. This initial report was followed by discussion in a second article of tens of families with apparent autosomal dominant inheritance of this condition. The similarities were described clinically to ADHD and mechanistically and therapeutically to disorders of ion channels, in particular to the muscle disorder hypokalemic periodic paralysis. Some females with premenstrual syndrome may have the same autosomal dominant disorder underlying their symptoms.

|
If these conservative measures do not bring about betterment, minimally invasive procedures such as a facet infiltration can be conducted to offer relief. In this procedure, a local anesthetic is injected directly into the respective joint, usually in combination with a cortisone preparation (corticosteroid). For long- term relief in more severe cases, Radio Frequency Ablation or Rhyzotomy, where the anterior and posterior spinal nerve root is burnt may be performed. A. Gangi, J. L. Dietemann, R. Mortazavi, D. Pfleger, C. Kauff, C. Roy: CT-guided interventional procedures for pain management in the lumbosacral spine.

The origin of the term "dry needling" is attributed to Janet G. Travell. In her 1983 book, Myofascial Pain and Dysfunction: Trigger Point Manual, Travell uses the term "dry needling" to differentiate between two hypodermic needle techniques when performing trigger point therapy. However, Travell did not elaborate on the details on the techniques of dry needling; the current techniques of dry needling were based on the traditional and western medical acupuncture. The two techniques Travell described are the injection of a local anesthetic and the mechanical use of a hypodermic needle without injecting a solution.

Painting from Koehler's Medicinal Plants (1887) Salvia officinalis has been used since ancient times for warding off evil, snakebites, increasing women's fertility, and more. The Romans referred to sage as the "holy herb," and employed it in their religious rituals. Theophrastus wrote about two different sages, a wild undershrub he called sphakos, and a similar cultivated plant he called elelisphakos. Pliny the Elder said the latter plant was called salvia by the Romans, and used as a diuretic, a local anesthetic for the skin, a styptic, and for other uses.

This method of toxicity treatment was invented by Dr. Guy Weinberg in 1998, and was not widely used until after the first published successful rescue in 2006. Evidence indicates Intralipid, a commonly available intravenous lipid emulsion, can be effective in treating severe cardiotoxicity secondary to local anesthetic overdose, including human case reports of successful use in this way (lipid rescue). However, the evidence at this point is still limited. Though most reports to date have used Intralipid, a commonly available intravenous lipid emulsion, other emulsions, such as Liposyn and Medialipid, have also been shown effective.

At a pH equal to the protonated base's pKa, the protonated (ionized) and unprotonated (unionized) forms of the molecule exist in equimolar amounts, but only the unprotonated base diffuses readily across cell membranes. Once inside the cell, the local anesthetic will be in equilibrium, with the formation of the protonated (ionized) form, which does not readily pass back out of the cell. This is referred to as "ion-trapping". In the protonated form, the molecule binds to the LA binding site on the inside of the ion channel near the cytoplasmic end.

A neurectomy is a type of nerve block involving the severing or removal of a nerve. This surgery is performed in rare cases of severe chronic pain where no other treatments have been successful, and for other conditions such as vertigo, involuntary twitching and excessive blushing or sweating. A brief "rehearsal" local anesthetic nerve block is usually performed before the actual neurectomy, to determine efficacy and detect side effects. The patient is typically under general anesthetic during the neurectomy, which is performed by a neurosurgeon or plastic surgeon.

The intra-aortic balloon pump was invented by Kantrowitz, working in conjunction with his brother, Arthur Kantrowitz. Inserted through the patient's thigh, it was directed into the aorta, and alternately expanded and contracted in order to reduce strain on the heart. Based on Kantrowitz's theory of "counterpulsation", the device inflated the balloon with helium gas when the heart relaxed and deflated it when the heart pumped blood. The pump did not require surgery and could be inserted using local anesthetic in an emergency room or at a patient's bedside.

Local trauma is also associated with aphthous stomatitis, and it is known that trauma can decrease the mucosal barrier. Trauma could occur during injections of local anesthetic in the mouth, or otherwise during dental treatments, frictional trauma from a sharp surface in the mouth such as broken tooth, or from tooth brushing. Hormonal factors are capable of altering the mucosal barrier. In one study, a small group of females with aphthous stomatitis had fewer occurrences of aphthous ulcers during the luteal phase of the menstrual cycle or with use of the contraceptive pill.

The people of Goa, the Konkan and Kanara coasts, and Coorg use the woody pericarp of the tiny fruits as a spice, particularly with seafood dishes. The spice is known as "triphal" in Marathi and "teppal" in Konkani - both words referring to the three lobes of the pericarp. The spice contains the same chemical ingredient, sanshool, a local anesthetic that causes a tingling sensation on the tongue. Sanshool is the main principle of Sichuan Pepper, which comes from the related species Zanthoxylum bungeanum and the Japanese/Korean pepper Zanthoxylum piperitum.

Use of lidocaine iontophoresis is effective for reducing pain and alleviating distress during venipuncture in children. A needle-free powder lignocaine delivery system has been shown to decrease the pain of venipuncture in children. Rapid dermal anesthesia can be achieved by local anesthetic infiltration, but it may evoke anxiety in children frightened by needles or distort the skin, making vascular access more difficult and increasing the risk of needle exposure to health care workers. Dermal anesthesia can also be achieved without needles by the topical application of local anesthetics or by lidocaine iontophoresis.

An alternative method of administration for ENT surgery is mixed with adrenaline and sodium bicarbonate, as Moffett's solution. Cocaine hydrochloride (Goprelto), an ester local anesthetic, was approved for medical use in the United States in December 2017, and is indicated for the introduction of local anesthesia of the mucous membranes for diagnostic procedures and surgeries on or through the nasal cavities of adults. Cocaine hydrochloride (Numbrino) was approved for medical use in the United States in January 2020. The most common adverse reactions in people treated with Goprelto are headache and epistaxis.

He wrote of the alkaloid's "colourless transparent prisms" and said that "Its solutions have an alkaline reaction, a bitter taste, promote the flow of saliva and leave a peculiar numbness, followed by a sense of cold when applied to the tongue." Niemann named the alkaloid "cocaine" from "coca" (from Quechua "kuka") + suffix "ine". Because of its use as a local anesthetic, a suffix "-caine" was later extracted and used to form names of synthetic local anesthetics. The first synthesis and elucidation of the structure of the cocaine molecule was by Richard Willstätter in 1898.

Leaves of the coca plant (Erythroxylum novogranatense var. Novogranatense), from which cocaine, a naturally occurring local anesthetic, is derived. An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia — in other words, to result in a temporary loss of sensation or awareness. They may be divided into two broad classes: general anesthetics, which result in a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body without necessarily affecting consciousness.

This led in 1976 to the development and introduction of Progestasert, a progesterone-containing product and the first progestogen-containing IUD. Unfortunately, the product had various problems that limited its use. These included a short duration of efficacy of only one year, a high cost, a relatively high 2.9% failure rate, a lack of protection against ectopic pregnancy, and difficult and sometimes painful insertions that could necessitate use of a local anesthetic or analgesic. As a result of these issues, Progestasert never became widely used, and was discontinued in 2001.

The pterygomandibular space is the area where local anesthetic solution is deposited during an inferior alveolar nerve block, a common procedure used to anesthetize the distribution of the inferior alveolar nerve. Rarely, pathogenic micro-organisms from the mouth may be seeded into the pterygomandibular space during this injection and cause a needle tract infection of the space. It is also occasionally reported that the needle breaks off and is retained in the pterygomandibular space during this injection. Minor oral surgery is then required to remove the fractured needle.

The treatment depends on the cause of the toothache, and frequently a clinical decision regarding the current state and long-term prognosis of the affected tooth, as well as the individual's wishes and ability to cope with dental treatment, will influence the treatment choice. Often, administration of an intra-oral local anesthetic such as lidocaine and epinephrine is indicated in order to carry out pain-free treatment. Treatment may range from simple advice, removal of dental decay with a dental drill and subsequent placement of a filling, to root canal treatment, tooth extraction, or debridement.

People may suffer from acute facial nerve paralysis, which is usually manifested by facial paralysis. Bell's palsy is one type of idiopathic acute facial nerve paralysis, which is more accurately described as a multiple cranial nerve ganglionitis that involves the facial nerve, and most likely results from viral infection and also sometimes as a result of Lyme disease. Iatrogenic Bell's palsy may also be as a result of an incorrectly placed dental local-anesthetic (inferior alveolar nerve block). Although giving the appearance of a hemiplegic stroke, effects dissipate with the drug.

Transurethral needle ablation (also called TUNA or transurethral radiofrequency ablation) is a technique that uses low energy radio frequency delivered through two needles to ablate excess prostate tissue. A cystoscope/catheter deploys the needles toward the obstructing prostate tissue is inserted into the urethra directly through the penis under local anesthetic before the procedure begins. The energy from the probe heats the abnormal prostate tissue without damaging the urethra. The resulting scar tissue later atrophies, reducing the size of the prostate which in turn reduces the constriction of the urethra.

The catheter is then advanced, also under ultrasound guidance, to the level of the groin or knee crease. Dilute local anesthesia is injected around and along the vein (perivascular infiltration) using ultrasound imaging to place the local anesthetic solution around the vein, mostly in a sub-facial location. This technique derives from the tumescent local anesthesia (TLA) method long used and proven safe and effective for some methods of liposuction. The laser is activated whilst the catheter or laser fiber is slowly withdrawn, resulting in obliteration of the saphenous vein along its entire length.

These blocks can be either single treatments, multiple injections over a period of time, or continuous infusions. A continuous peripheral nerve block can be introduced into a limb undergoing surgery – for example, a femoral nerve block to prevent pain in knee replacement.UCSD. Regional anesthesia Local anesthetic nerve blocks are sterile procedures that are usually performed in an outpatient facility or hospital. The procedure can be performed with the help of ultrasound, fluoroscopy (a live X-ray), or CT to guide the physician in the placement of the needle.

An arthrogram is a series of images of a joint after injection of a contrast medium, usually done by fluoroscopy or MRI. The injection is normally done under a local anesthetic such as Novocain or lidocaine. The radiologist or radiographer performs the study using fluoroscopy or x-ray to guide the placement of the needle into the joint and then injects around 10 ml of contrast based on age. There is some burning pain from the anesthetic and a painful bubbling feeling in the joint after the contrast is injected.

Once scanned at the proper frequency, the chip responded with a unique 16-digit number which could be then linked with information about the user held on a database for identity verification, medical records access and other uses. The insertion procedure was performed under local anesthetic in a physician's office. Privacy advocates raised concerns regarding potential abuse of the chip, with some warning that adoption by governments as a compulsory identification program could lead to erosion of civil liberties, as well as identity theft if the device should be hacked.

Epidural administration (from Ancient Greek ἐπί, "on, upon" + dura mater) is a method of administration in which a drug is injected into the epidural space around the spinal cord. The epidural route is used by physicians and nurse anesthetists to administer local anesthetic agents, analgesics, diagnostic medicines such as radiocontrast agents, and other medicines such as glucocorticoids. Epidural administration is often accomplished through use of a catheter placed into the epidural space. The technique of epidural administration was first described in 1921 by Spanish military surgeon Fidel Pagés.

Prolotherapy involves the injection of an irritant solution into a joint space, weakened ligament, or tendon insertion to relieve pain. Most commonly, hyperosmolar dextrose (a sugar) is the solution used; glycerine, lidocaine (a commonly used local anesthetic), phenol, and sodium morrhuate (a derivative of cod liver oil extract) are other commonly used agents. The injection is administered at joints or at tendons where they connect to bone. Prolotherapy treatment sessions are generally given every two to six weeks for several months in a series ranging from 3 to 6 or more treatments.

The needle goes in about 3–4 cm and a single shot of local anesthetic is injected or a catheter is placed. The most common local anesthetics used at the site of the nerves are bupivicaine, mepivicaine, and chloroprocaine. There is a very high chance that the phrenic nerve, which innervates the diaphragm, will be blocked so this block should only be done on patients who have use of their accessory respiratory muscles. The block may not affect the C8 and T1 roots which supply part of the hand, so it is usually not done for hand surgeries.

In 1923 he contracted a bad cold during the Easter season that also saw him suffer from several haemorrhages. Doctors later assessed Kern and concluded that he had to have an operation on 10 August 1923 to remove four of his ribs. Local anesthetic was used and so he had to endure extreme pain and he never recovered from this operation which caused an even greater deterioration in his health - he had also refused to take painkillers during his time of rest. Kern apologized to his surgeon for inconveniences caused during the operation - that being the pain he felt during it.

In Peru, the ancient Incas are believed to have used the leaves of the coca plant as a local anaesthetic in addition to its stimulant properties. It was also used for slave payment and is thought to play a role in the subsequent destruction of Incas culture when Spaniards realized the effects of chewing the coca leaves and took advantage of it. Cocaine was first used as a local anesthetic in 1884. The search for a less toxic and less addictive substitute led to the development of the aminoester local anesthetics stovaine in 1903 and procaine in 1904.
|
|
Since then, several synthetic local anesthetic drugs have been developed and put into clinical use, notably lidocaine in 1943, bupivacaine in 1957, and prilocaine in 1959. The invention of clinical use of local anaesthesia is credited to the Vienna School which included Sigmund Freud (1856-1939), Carl Koller (1857-1944) and Leopold Konigstein (1850-1942). They introduced local anaesthesia, using cocaine, through ‘self-experimation’ on their oral mucosa before introducing it to animal or human experimentation. The Vienna school first started using cocaine as local anaesthesia in ophthalmology and it was later incorporated into ophthalmologic practice.

It was discovered accidentally in 1958 during research on a local anesthetic, by MacFarlan Smith of Gorgie, Edinburgh, Scotland. Research has shown that TAS2Rs (taste receptors, type 2, also known as T2Rs) such as TAS2R38 coupled to the G protein gustducin are responsible for the human ability to taste bitter substances. They are identified not only by their ability to taste for certain "bitter" ligands, but also by the morphology of the receptor itself (surface bound, monomeric). The TAS2R family in humans is thought to comprise about 25 different taste receptors, some of which can recognize a wide variety of bitter-tasting compounds.

When C. anthropophaga causes cutaneous myiasis, the larvae more often than not can be removed without any incision. Covering the punctum (the breathing hole) with petroleum jelly or similar substances cuts off the air supply and forces the maggot to the surface, where it is easy to capture with forceps. If this does not work, local anesthetic can be administered and an incision made to widen the punctum and remove the maggot. Another treatment discussed in the March 2014 Journal of the American Medical Association is to inject a combination of anaesthetic and epinephrine into the insect's chamber.

Real-time three-dimensional ultrasound is used during peripheral nerve blockade procedures to identify relevant anatomy and monitor the spread of local anesthetic around the nerve. Peripheral nerve blockades prevent the transmission of pain signals from the site of injury to the brain without deep sedation, which makes them particularly useful for outpatient orthopedic procedures. Real-time 3D ultrasound allows muscles, nerves and vessels to be clearly identified while a needle or catheter is advanced under the skin. 3D ultrasound is able to view the needle regardless of the plane of the image, which is a substantial improvement over 2D ultrasound.

A fiberotomy involves the detachment of the fibers that attach the tooth to the bone via the gum. The fibers act much like twisted rubber bands and releasing the tension between the fibers and the tooth reduces the forces that attempt to pull the tooth back to its original position. It is performed near the completion of the orthodontics and is shown to be effective in preventing the relapse of teeth. To perform this procedure, there is the surgical cutting of disrupted transeptal fibres by making a gingival crevicular incision under local anesthetic after orthodontic alignment.

|
Nerve blocks involve injecting a small amount of local anesthetic around a nerve or into a synovial structure (such as a joint or tendon sheath) in order to block the perception of pain in a specific area. After the substance is injected, it is given a few minutes to take effect. The block is then tested by pushing a blunt object, such as a ballpoint pen, into the area that is supposed to be desensitized. If the horse does not react to this pressure, the area is desensitized, and the horse is trotted to see if the lameness has improved.

Continuous wound infiltration first appeared on the market in the late 1990s when a US company (I-Flow Corporation) found a way to evenly spread and continuously infiltrate a local anesthetic via a specially designed multi holed catheter inside the wound, to enable post- operative pain treatment. The benefits of wound infiltration are quite prominent which is the reason why "single shot" wound infiltration has already been done for several decades. The limiting factor of the single shot approach has always been the half-life period of the local anesthetics which would not allow a long term post-op pain treatment.

When local anesthetic is injected around a larger diameter nerve that transmits sensation from an entire region it is referred to as a nerve block or regional nerve blockade. Nerve blocks are commonly used in dentistry, when the mandibular nerve is blocked for procedures on the lower teeth. With larger diameter nerves (such as the interscalene block for upper limbs or psoas compartment block for lower limbs) the nerve and position of the needle is localized with ultrasound or electrical stimulation. The use of ultrasound may reduce complication rates and improve quality, performance time, and time to onset of blocks.

Central neuraxial anesthesia is the injection of local anesthetic around the spinal cord to provide analgesia in the abdomen, pelvis or lower extremities. It is divided into either spinal (injection into the subarachnoid space), epidural (injection outside of the subarachnoid space into the epidural space) and caudal (injection into the cauda equina or tail end of the spinal cord). Spinal and epidural are the most commonly used forms of central neuraxial blockade. Spinal anesthesia is a "one-shot" injection that provides rapid onset and profound sensory anesthesia with lower doses of anesthetic, and is usually associated with neuromuscular blockade (loss of muscle control).
|
|
At this time an appropriately sized (b) Foley catheter will be inserted through the repair and into the bladder (and connected to a urinary drainage system), and the incision closed (layer by layer). Some surgeons will inject a local anesthetic such as 2% plain lidocaine or 0.5% bupivicaine into the areas to allow the patient an additional period of relief from discomfort. Micro-doppler circulatory measurement of the penile vasculature is performed at way points throughout the procedure, and a final assessment is taken and recorded. The incision is inspected and dressed, and the patient is discharged to recovery.

|
Many procedures or diagnostic tests do not require "general anesthesia" and can be performed using various forms of sedation or regional anesthesia, which can be performed to induce analgesia in a region of the body. For example, epidural administration of a local anesthetic is commonly performed on the mother during childbirth to reduce labor pain while permitting the mother to be awake and active in labor and delivery. In the United States, anesthesiologists may also perform non-surgical pain management (termed pain medicine) and provide care for patients in intensive care units (termed critical care medicine).

Saint Apollonia, patron saint for toothaches, holds one of her own extracted teeth in a pair of forceps (Nuremberg Chronicle, Hartmann Schedel, 1493) American advertisement from 1885 offering "instantaneous cure" for toothache with "Cocaine toothache drops". Cocaine was the first local anesthetic, but its addictive and other dangerous side effects eventually led to its use being virtually abandoned by modern health care. A monk with a toothache examines himself in a mirror, painting by Carl Bloch from 1875. The first known mention of tooth decay and toothache occurs on a Sumerian clay tablet now referred to as the "Legend of the worm".

Chalazion surgery is a simple procedure that is generally performed as a day operation, and the person does not need to remain in the hospital for further medical care. Sometimes, as a last resort, surgery is performed. The eyelid is injected with a local anesthetic, a clamp is put on the eyelid, then the eyelid is turned over, an incision is made on the inside of the eyelid, and the chalazion is drained and scraped out with a curette. A scar on the upper lid can cause discomfort as some people feel the scar as they blink.

MRI showing subacromial impingement with partial rupture of the supraspinatus tendon, but no retraction or fatty degeneration of the supraspinatus muscle. Impingement syndrome can be diagnosed by a targeted medical history and physical examination, but it has also been argued that at least medical imaging (generally X-ray initially) and/or response to local anesthetic injection is necessary for workup. On physical exam, the physician may twist or elevate the patient's arm to test for reproducible pain (the Neer sign and Hawkins-Kennedy test). These tests help localize the pathology to the rotator cuff; however, they are not specific for impingement.

|
Diagnosis is based on physical examination and an x-ray. A physical examination can identify point tenderness, pain at the AC joint with cross-arm adduction, and pain relief with an injection of a local anesthetic. The cross-arm adduction will produce pain specifically at the AC joint and will be done by elevating the arm to a 90° angle, flexing the elbow to a 90° angle, and adducting the arm across the chest. The pain in the shoulder is hard to pinpoint due to the shared innervation of the AC joint and the glenohumeral joint.

Another 2015 review states that it is safe in those who are otherwise healthy. The addition of dexamethasone to a nerve block or if given intravenously for surgery can prolong the duration of an upper limb nerve block leading to reduction in postoperative opioid consumption Complications of nerve blocks most commonly include infection, bleeding, and block failure. Nerve injury is a rare side effect occurring roughly 0.03-0.2% of the time. The most significant complication of nerve blocks is local anesthetic systemic toxicity (LAST) which can include neurologic and cardiovascular symptoms including cardiovascular collapse and death.

Forming the exterior end of the infraorbital canal, the infraorbital foramen communicates with the infraorbital groove, the canal's opening on the interior side. The ramifications of the three principal branches of the trigeminal nerve—at the supraorbital, infraorbital, and mental foramen—are distributed on a vertical line (in anterior view) passing through the middle of the pupil. The infraorbital foramen is used as a pressure point to test the sensitivity of the infraorbital nerve. Palpation of the infraorbital foramen during an extraoral examination or an administration of a local anesthetic agent will cause soreness to the area.

Fidel Pagés visiting injured soldiers at the Docker Hospital in Melilla in 1909. The first record of an epidural injection is from 1885, when American neurologist James Corning of Acorn Hall in Morristown, NJ used the technique to perform a neuraxial blockade. Corning inadvertently injected 111 mg of cocaine into the epidural space of a healthy male volunteer, although at the time he believed he was injecting it into the subarachnoid space. Following this, in 1901 Fernand Cathelin first reported intentionally blocking the lowest sacral and coccygeal nerves through the epidural space by injecting local anesthetic through the sacral hiatus.

Surgical treatment of trigger thumb can be complicated by injury to the digital nerves, scarring, tenderness, or a contracture of the joint. A higher rate of symptom improvement has been observed when surgical management is paired with corticosteroid injections when compared to corticosteroid injections alone. Treatment consists of injection of a corticosteroid such as methylprednisolone often combined with a local anesthetic (lidocaine) at the site of maximal inflammation or tenderness around the A1 pulley of the finger in the palm. The infiltration of the affected site can be performed using standard anatomic landmarks or sonographically guided, and often needs to be repeated 2 or three times to achieve remission.

Usual standards for musculoskeletal interventional procedures apply include review of previous imaging, informed consent and appropriate local anesthetic. The use of a high-frequency (> 10 MHz) linear array transducer is recommended, but lower-frequency curvilinear probes may be occasionally required to visualize deep structures in larger patients. A preliminary diagnostic sonographic examination, including color Doppler of the area to be punctured is necessary to define the relationship of adjacent neurovascular structures.Initially largely copied from: Creative Commons Attribution 4.0 International License (CC-BY 4.0) Injections should be performed with adherence to aseptic technique although this varies between institutions and radiologists attributable to resources, training, perceived risk and experience.

Cloudy CSF from a person with meningitis due to Streptococcus Gram stain of meningococci from a culture showing Gram negative (pink) bacteria, often in pairs A lumbar puncture is done by positioning the person, usually lying on the side, applying local anesthetic, and inserting a needle into the dural sac (a sac around the spinal cord) to collect cerebrospinal fluid (CSF). When this has been achieved, the "opening pressure" of the CSF is measured using a manometer. The pressure is normally between 6 and 18 cm water (cmH2O); in bacterial meningitis the pressure is usually elevated. In cryptococcal meningitis, intracranial pressure is markedly elevated.

Alexandru Tzaicu attended high school and medical studies in Iași, being a scholar of the Adamachi Fund of the Romanian Academy. In 1909, in order to demonstrate the qualities of the spinal anaesthesia method developed by the surgeons Thoma Ionescu and Amza Jianu, Tzaicu performed an inguinal hernia self-operation. This surgical intervention was described in paper and later allowed him to get a doctorate in surgery. Tzaicu self- operated his left groin, being the first self-intervention of this kind in the world (the next "first" being the American surgeon Evan O'Neill Kane who performed in 1921 self-surgery for appendicitis under local anesthetic with novocaine).

Methylprednisolone acetate, sold under the brand names Depo-Medrol among others, is a synthetic glucocorticoid corticosteroid and a corticosteroid ester—specifically the C21 acetate ester of methylprednisolone—which is used in clinical and veterinary medicine. It has been formulated as an aqueous suspension for intramuscular, intra-articular, soft tissue, and intralesional injection alone and in combination with lidocaine, a local anesthetic. Methylprednisolone acetate was previously suspended with polyethylene glycol but is no longer formulated with this excipient due to concerns about possible toxicity. Depot methylprednisolone acetate is a depot injection and is absorbed slowly with a duration of weeks to months with a single intramuscular injection.

In addition to physical damage, peripheral neuropathy may be caused by many other medical problems, including genetic conditions, metabolic conditions such as diabetes, inflammatory conditions such as Guillain–Barré syndrome, vitamin deficiency, infectious diseases such as leprosy or shingles, or poisoning by toxins such as heavy metals. Many cases have no cause that can be identified, and are referred to as idiopathic. It is also possible for nerves to lose function temporarily, resulting in numbness as stiffness—common causes include mechanical pressure, a drop in temperature, or chemical interactions with local anesthetic drugs such as lidocaine. Physical damage to the spinal cord may result in loss of sensation or movement.

On 10 February, the chief surgeon, Dr. Leonardo de Sousa Castro Freire, assisted by Dr. Elvas removed two ribs only under local anesthetic, since, because of the condition of her heart, she could not be fully anesthetised: she suffered terrible pain, which she said would help to convert many sinners. On 19 February, Jacinta asked the hospital chaplain who heard her confession to bring her Holy Communion and administer Extreme Unction because she was going to die "the next night". He told her that her condition was not that serious and that he would return the next day. The following day Jacinta was dead.

Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually long. It is a safe and effective form of anesthesia performed by anesthesiologists and nurse anesthetists which can be used as an alternative to general anesthesia commonly in surgeries involving the lower extremities and surgeries below the umbilicus. The local anesthetic or opioid injected into the cerebrospinal fluid provides anesthesia, analgesia, and motor and sensory blockade. The tip of the spinal needle has a point or small bevel.

In many other uses to destroy larger lesions, a local anesthetic injection or regional nerve block is used. The pain from hyfrecation is due to the burning of tissue, and the pain of electric current is absent, due to the high (radio) frequency which does not directly cause discharge of nerves. Although the hyfrecator is not used primarily to cut tissue, it may be used in a secondary capacity to control bleeding, after tissue is cut by a standard surgical scalpel, or else it may be used to partly destroy superficial tissue, that is then removed by the scraping action of a curette. These are done under local anesthesia.

Povidone-iodine solution is applied to the conjunctiva at the site of injection. Another dose of local anesthetic may be given to the conjunctival surface again (for example, by placing a cotton swab soaked with the anesthetic drug solution over the targeted region), which is followed by the reapplication of PVP-I solution. The injection site is measured and marked with a measuring caliper or other devices. The patient is then told to look away from the injection site to show the quadrant to be injected, and the doctor inserts the needle at the target site in a single motion into the mid- vitreous cavity.

Comrie (right foreground) with the Ottawa Senators, fighting with Brian Rafalski as referees attempt to break it up Comrie scored his first goal for the Senators versus the Boston Bruins on January 9, 2007 at Scotiabank Place in Ottawa, Ontario. Whenever Comrie scored a goal at Scotiabank Place, his goal song was "Black Gloves" by the Belgian band Goose. He helped Ottawa throughout the playoffs despite having an injured shoulder that required local anesthetic to numb the pain, this prevented him from reaching down to tie his skates. The Senators made it to the Stanley Cup Finals, losing to the Anaheim Ducks, in a 4–1 series decision.

Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve. Neurolytic block, the deliberate temporary degeneration of nerve fibers through the application of chemicals, heat, or freezing, produces a block that may persist for weeks, months, or indefinitely. Neurectomy, the cutting through or removal of a nerve or a section of a nerve, usually produces a permanent block.

For patients who present in an emergency setting with symptomatic bradycardias, usually drugs like atropine or sympathomimetic drugs (epinephrine or dopamine) can be used to increase the heart rate to an adequate level until the underlying cause of the bradycardia can be isolated and then, possibly, a permanent pacemaker can be placed. For patients for whom transvenous pacing is chosen, the procedure is done at the bedside with a local anesthetic alone or in conjunction with conscious sedation. The pacing electrode is advanced through the vein under fluoroscopic and electrocardiographic guidance. An x-ray after the procedure is always obtained to confirm placement of the pacing electrode.

From 1949 to 1953, 374 experimental surgeries were performed on TB patients, without the use of general anesthetic at the Charles Camsell Indian Hospital. In 1956, Charles Camsell Indian Hospital in Edmonton used its patients to test versions of para-aminosalicylic acid (PAS); they also performed trials of a thyroid-stimulating hormone for a study of hypothyroidism in Indigenous people. Besides treatment with drugs, surgical procedures were performed on patients, including the intentional collapsing of lungs and removal of ribs, causing deformities. At Charles Camsell in Edmonton, medical staff used local anesthetic on Indigenous patients during such processes as chest surgery and rib removals, so that the patients would be awake and aware during the procedures.

J Dent Res 1996; 75(Special Issue):247. 19 reported paresthesia cases in Ontario for 1994 were reviewed, concluding that the incidence of paresthesia was 2.05 per million injections of 4% anesthetic drugs. Another follow up study by Miller and Haas published in 2000,Miller PA, Haas DA. Incidence of local anesthetic-induced neuropathies in Ontario from 1994–1998. J Dent Res 2000; 79 (Special Issue):627. concluded that the incidence of paresthesia from either prilocaine or articaine (the only two 4% drugs in the dental market) was close to 1:500,000 injections.

A local anesthetic and moderate sedation are used but a general anaesthetic is not required, hence the person remains awake throughout the procedure. After inserting the catheter into the vein of the neck (right internal jugular vein) or groin (right femoral vein), a hollow tube is introduced through the catheter and passed to the affected blocked lung arteries. X-rays and pressures in the narrowed arteries are assessed by the specialist team before a thin wire with a deflated balloon is guided through the blood vessels to the site of blockage, where the balloon is then inflated. This mainly disrupts the organised thrombus and to a lesser degree presses it against the walls of the arteries.

Fast-acting voltage-gated sodium channels (Nav1.5) found in high concentrations in the ventricular myocytes, open at a membrane potential of −80 mv in typical cardiac rhythm. This will result in a rapid upstroke of an action potential that leads to contraction of the ventricles. Class 1c drugs have local anesthetic properties and have a high affinity for open Nav1.5 (but not closed or inactive Nav1.5), thus irreversibly binding and reducing the fast Na+ influx. Interactions of Lorcainide with Nav1.5 are time and voltage dependent. Class 1c drugs have a characteristically slow dissociation rate, which will slow the upstroke duration and amplitude of ventricular myocytes’ action potential and prolong the PR, QRS and QT intervals of an ECG.

Once ACNES is considered based on the patient's history, the diagnosis can be made via a thorough physical examination: looking for a painful spot, which worsens by tensing the abdominal muscles with lifting the head and straightened legs (Carnett's sign). Almost always, a small area of maximal pain is covered by a larger area of altered skin sensibility with somatosensory disturbances such as hypoesthesia as well as hyperesthesia or hyperalgesia and change of cool perception. Pinching the skin between thumb and index finger is extremely painful compared to the opposite non-involved side. Confirmation of a diagnosis of ACNES is warranted using an abdominal wall infiltration with a local anesthetic agent near the painful spot.

Prior to the procedure, compatible blood is obtained. This is usually type O, RhD-negative, and antigen-negative for maternal RBC antibodies. The selected blood then undergoes irradiation and leukocyte reduction.. Antenatal corticosteroids are typically given to mothers before IUT to anticipate the need for an emergency cesarean section The procedure is usually performed in a hospital under sterile conditions, within or near an operating room in case an emergency cesarean section is necessary due to complications caused by the procedure. The mother's abdomen is cleaned with an antiseptic solution, and she may or may not be given a local anesthetic injection to numb the abdominal area where the transfusion needle will be inserted.

Phenyltropanes (PTs) are a family of chemical compounds originally derived from structural modification of cocaine. The main feature differentiating phenyltropanes from cocaine is that they lack the ester functionality at the 3-position terminating in the benzene; and thusly the phenyl is attached direct to the tropane skeleton with no further spacer (therefore the name "phenyl"-tropane) that the cocaine benzoyloxy provided. The original purpose of which was to extirpate the cardiotoxicity inherent in the local anesthetic "numbing" capability of cocaine (since the methylated benzoate ester is essential to cocaine's blockage of sodium channels which cause topical anesthesia) while retaining stimulant function. These compounds present many different avenues of research into therapeutic applications, particularly in addiction treatment.

At this time, using micro surgical technique, the anastomosis is completed and fibrin glue is applied to the anastomotic suture line to help prevent leakage and fistula formation. The silicone guide catheter will then be withdrawn from the penis and (a) replaced by an appropriately sized Foley catheter (and urinary drainage system), and the incision closed (layer by layer). Some surgeons will inject a local anesthetic such as 2% plain lidocaine or 0.5% bupivicaine into the areas to allow the patient an additional period of relief from discomfort. Micro-doppler circulatory measurement of the penile vasculature is performed at way points throughout the procedure, and a final assessment is taken and recorded.

In 1974, a group of abortion rights activists founded the Canadian Association for the Repeal of the Abortion Law in Ottawa.Canadian Abortion Rights Action League history The aim of CARAL was to support Morgentaler's challenge of the 1969 abortion law requiring approval of a Therapeutic Abortion Committee (TAC) before an abortion could be legally performed (without requiring TACs to be formed or to meet). The organization formed provincial and local chapters across Canada and helped to raise funds for Morgentaler's legal fees. The group also supported Morgentaler's use of vacuum aspiration under local anesthetic as safer and less invasive than the dilation and curettage (D&C;) that was traditionally performed at hospitals for abortions or after miscarriages.

This formulation is also sold in Australia as Bonjela Teething Gel, for the treatment of teething pain in babies. Bonjela Teething Gel in the UK and Ireland however is a different formulation, as salicylate-based products cannot be used in under-16's in the UK. This formulation of Bonjela Teething Gel contains the local anesthetic lidocaine and the antiseptic cetalkonium chloride. The range also includes Bonjela Complete Plus, which acts by forming a protective barrier over the ulcer. Bonjela is distributed by Reckitt Benckiser Healthcare and is available in the United Kingdom, France, Ireland, South Africa, Nigeria, Australia, New Zealand, Singapore, Malaysia, Hong Kong, Thailand, Pakistan and many Caribbean countries (such as Trinidad and Tobago).

In acute closed lock, it is theorized that the upper joint space is inflated from its normally collapsed state during this procedure, and this extra space frees up the articular disc which returns to its correct position. This is the least invasive, and easiest to carry out of the surgical options. It can be carried out under local anesthetic (and for this reason is cheaper than arthroscopy, although it may also carried out under general anesthetic) and has minimal complications. Although it has been suggested that arthrocentesis decreases pain, increases maximal incisal opening and has prolonged effects, when the procedure was investigated by a systematic review, the impact on pain was comparable to arthroscopy and the results are unstable.

During one part of the visit, the delegation was shown a patient undergoing major surgery while fully awake, ostensibly receiving acupuncture rather than anesthesia. Later it was found that the patients selected for the surgery had both a high pain tolerance and received heavy indoctrination before the operation; these demonstration cases were also frequently receiving morphine surreptitiously through an intravenous drip that observers were told contained only fluids and nutrients. One patient receiving open heart surgery while awake was ultimately found to have received a combination of three powerful sedatives as well as large injections of a local anesthetic into the wound. After the National Institute of Health expressed support for acupuncture for a limited number of conditions, adoption in the US grew further.

It is weaker than morphine as an analgesic but longer-lasting in effects, and was thought to have more local anesthetic effect than morphine, though with a somewhat greater tendency to cause histamine reactions like itching and rash. In addiction studies conducted in human subjects in the 1950s, myrophine did not substitute for morphine in withdrawal, did not produce notable morphine-like effects, and did not produce addiction or dependence regardless of dose or how it was administered. Consequently, it was thought to be useful in treating pain in addicts who were being detoxified from other opioid drugs. It is a Schedule I drug in the US, considered to have high potential for abuse and no medical applications, and is controlled under international drug conventions.

RISUG works by an injection into the vas deferens, the vessel through which the sperm moves before ejaculation. RISUG is similar to vasectomy in that a local anesthetic is administered, an incision is made in the scrotum, and the vasa deferentia are injected with a polymer gel (rather than being cut and cauterized). In a matter of minutes, the injection coats the walls of the vasa with a clear gel made of 60 mg of the copolymer styrene/maleic anhydride (SMA) with 120 µl of the solvent dimethyl sulfoxide. The copolymer is made by irradiation of the two monomers with a dose of 0.2 to 0.24 megarad for every 40 g of copolymer and a dose rate of 30 to 40 rad/s.

The lateral pectoral nerve is important in the pain response after breast augmentation and mastectomy, and especially in breast implant surgery, when the implant is inserted by the subpectoral route. The pectoral nerves can be anesthetized (blocked) intraoperatively by the surgeon under direct vision by three injections - one to block the medial pectoral nerve, the second to block the perforating branches of the medial pectoral nerve, and the third to block the lateral pectoral nerve. An ultrasound-guided pectoral nerve block can also be performed preventively before the operation by an anesthesiologist, experienced in regional anesthesia. It is safe and relies on ultrasound imaging to localize the pectoralis major and minor muscles, the presumed course of the pectoral nerves and the optimal spread of the local anesthetic.

G-spot amplification (also called G-spot augmentation or the G-Shot) is a procedure intended to temporarily increase pleasure in sexually active women with normal sexual function, focusing on increasing the size and sensitivity of the G-spot. G-spot amplification is performed by attempting to locate the G-spot and noting measurements for future reference. After numbing the area with a local anesthetic, human engineered collagen is then injected directly under the mucosa in the area the G-spot is concluded to be in. A position paper published by the American College of Obstetricians and Gynecologists in 2007 warns that there is no valid medical reason to perform the procedure, which is not considered routine or accepted by the College; and it has not been proven to be safe or effective.

Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the interior chest wall. CRT is indicated in patients suffering from a low ejection fraction (typically <35%) indicating heart failure, where electrical activity has been compromised, with prolonged QRS duration to >120 ms. The insertion of electrodes into the ventricles is done under local anesthetic, with access to the ventricles most commonly via the subclavian vein, although access may be conferred from the axillary or cephalic veins. Right ventricular access is direct, while left ventricular access is conferred via the coronary sinus (CS).

A vaporizer holds a liquid anesthetic and converts it to gas for inhalation (in this case sevoflurane) Anesthesia is a combination of the endpoints (discussed above) that are reached by drugs acting on different but overlapping sites in the central nervous system. General anesthesia (as opposed to sedation or regional anesthesia) has three main goals: lack of movement (paralysis), unconsciousness, and blunting of the stress response. In the early days of anesthesia, anesthetics could reliably achieve the first two, allowing surgeons to perform necessary procedures, but many patients died because the extremes of blood pressure and pulse caused by the surgical insult were ultimately harmful. Eventually, the need for blunting of the surgical stress response was identified by Harvey Cushing, who injected local anesthetic prior to hernia repairs.

Research supports the use of NSAIDs for the control of pain associated with veterinary procedures such as dehorning and castration of calves. The best effect is obtained by combining a short-term local anesthetic such as lidocaine with an NSAID acting as a longer term analgesic. However, as different species have varying reactions to different medications in the NSAID family, little of the existing research data can be extrapolated to animal species other than those specifically studied, and the relevant government agency in one area sometimes prohibits uses approved in other jurisdictions. For example, ketoprofen's effects have been studied in horses more than in ruminants but, due to controversy over its use in racehorses, veterinarians who treat livestock in the United States more commonly prescribe flunixin meglumine, which, while labeled for use in such animals, is not indicated for post-operative pain.

Hingson and Southworth first used this technique in an operation to remove the varicose veins of a Scottish merchant seaman. Rather than removing the caudal needle after the injection as was customary, the two surgeons experimented with a continuous caudal infusion of local anesthetic. Hingson then collaborated with Edwards, the chief obstetrician at the Marine Hospital, to study the use of continuous caudal anesthesia for analgesia during childbirth. Hingson and Edwards studied the caudal region to determine where a needle could be placed to deliver anesthetic agents safely to the spinal nerves without injecting them into the cerebrospinal fluid. The first use of continuous caudal anesthesia in a laboring woman was on January 6, 1942, when the wife of a United States Coast Guard sailor was brought into the Marine Hospital for an emergency Caesarean section.

Press around the country responded well to the album, saying: [Strike the Mics was] "the kind of thing that should please both fans of modern rock and those whose tastes run more towards classic sounds," "Vintage Blue has created an album in Strike The Mics that will please even the most fickle of rock fans," and that "The new album finds the band tighter, leaner and more focused on contributing to the Great American Songbook than ever before." Additionally, Vintage Blue was featured on WXRT's show Local Anesthetic on April 8, 2012. The band also was added to the rotation of AAA radio station 98.1 WOCM, Ocean City, Maryland and to over 150 College and Community Radio Stations in North America, including: WMHW, KLCZ, WLCA, WMUH, WRSU, KDHX, WRDP, KFAI, WIIT, and WMXM. The most significant online exposure piece came as the band was featured on Windows Media Guide.

Because of the unique social setting of London medicine, anesthesia had become its own speciality there by the end of the nineteenth century, while in the rest of the United Kingdom and most of the world anesthesia remained under the purview of the surgeon who would assign the task to a junior doctor or nurse. After Austrian diplomat Karl von Scherzer brought back sufficient quantities of coca leaves from Peru, in 1860 Albert Niemann isolated cocaine, which thus became the first local anesthetic. In 1871, the German surgeon Friedrich Trendelenburg (1844–1924) published a paper describing the first successful elective human tracheotomy to be performed for the purpose of administration of general anesthesia. In 1880, the Scottish surgeon William Macewen (1848–1924) reported on his use of orotracheal intubation as an alternative to tracheotomy to allow a patient with glottic edema to breathe, as well as in the setting of general anesthesia with chloroform.

This is the examination of the cerebrospinal fluid that envelops the brain and the spinal cord; the sample is obtained with a needle that is passed under local anesthetic into the spine. In pituitary apoplexy the results are typically normal, although abnormalities may be detected if blood from the pituitary has entered the subarachnoid space. If there is remaining doubt about the possibility of subarachnoid hemorrhage (SAH), a magnetic resonance angiogram (MRI with a contrast agent) may be required to identify aneurysms of the brain blood vessels, the most common cause of SAH. Professional guidelines recommend that if pituitary apoplexy is suspected or confirmed, the minimal blood tests performed should include a complete blood count, urea (a measure of renal function, usually performed together with creatinine), electrolytes (sodium and potassium), liver function tests, routine coagulation testing, and a hormonal panel including IGF-1, growth hormone, prolactin, luteinizing hormone, follicle- stimulating hormone, thyroid-stimulating hormone, thyroid hormone, and either testosterone in men or estradiol in women.

These procedures aim to inject bio-compatible material into the walls of the anal canal, aiming to bulk out these tissues. This may bring the walls of the anal canal into tighter contact, raising the resting pressure, creating more of a barrier to the loss of stool, and reducing FI. Originally, this technique was described for urinary incontinence, but has since been used for FI, especially passive soiling due to IAS dysfunction. This measure has many advantages over more invasive surgery, since there are rarely any serious complications and the procedure can be carried out under local anesthetic on an out patient basis. Many different materials have been used as perianal injectable bulking agents, including: autologous fat (fat tissue transferred from elsewhere in the body), Teflon, bovine glutaraldehyde cross-linked collagen (collagen from cows), carbon-coated zirconium beads, polydimethylsiloxane elastomer, dextranomer/non-animal stabilised hyaluronic acid, hydrogel cross-linked with polyacrylamide, porcine dermal collagen (collagen from pig skin), and synthetic calcium hydroxylapatite ceramic microspheres.

Völgyesi started medical studies in 1912 at the University of Medicine in Budapest. He was deployed in 1916, before graduating from medical school, to the battle fought between Hungarian and Russian troops on the Dniester River, where he recounts, “I was doing my medical supervising circuit on horseback on a beautiful sunny morning in May, and listening with a smile to the trivial complaints of the healthy sunburnt young artillerymen from Budapest...suddenly the Russian artillery opened fire...That was the first time I heard the terrible, agonized death-cry of HELP -- break forth simultaneously from a whole crowd of men...I had to amputate limbs with a penknife, and without any local anesthetic.” Völgyesi received his medical degree in 1917 and soon after established a successful private practice, which was initially shared with the celebrated lay hypnotist Alfréd Perthes. In 1912-1914, Völgyesi was an intern, and later teaching assistant at the Anatomical Institute of the University of Budapest.

The urological surgeon or anesthesia practitioner may also choose to administer a narcotic analgesic such as fentanyl citrate, depending on the level of discomfort anticipated by the surgeon. In some cases, usually where longer strictures are present, a rapidly metabolized hypnotic agent such as propofol may be selected, as this allows for the immediate induction of short-term general anesthesia (note:endotracheal intubation will also be necessary if general anesthesia is administered). Constant monitoring of vital signs including pulse oximetry, cardiac monitoring (ECG), body temperature and blood pressure are carried out by the anesthesia practitioner until the patient is discharged post-operatively to the post-surgical recovery unit. A topical anesthetic, usually viscous lidocaine is instilled into the urethra, and a penile (crown) clamp is applied for at least five minutes, then removed immediately prior to the insertion of a cystoscope equipped with a transurethral injection system containing a local anesthetic (most often 2% (plain) lidocaine, or 0.5% (plain) bupivicaine).

The urological surgeon will inject the anesthetic at the twelve o'clock, four o'clock, and eight o'clock positions at the face of the stricture using infiltrative technique, and ensuring that the entire length of the stricture has been medicated. The cystoscope (and injection system) will be withdrawn, and sufficient time will be allowed for the local anesthetic to take effect (usually five-to-ten minutes). At this time a rigid urethrotome or a flexible cystoscope/urethrotome combination will be inserted and guided to the face of the stricture and a small blade towards the tip of the instrument will be deployed using a trigger mechanism to cut the stricture at locations determined by the surgeon. Upon completion of the internal incision(s), the instrument is withdrawn and an appropriately sized Foley catheter will be inserted through the repair and into the urinary bladder, and locked into place by filling its balloon (positioned inside of the bladder near the urethral junction) with sterile water.

Local anesthetic injections into the nerves or sensitive areas of the stump may relieve pain for days, weeks, or sometimes permanently, despite the drug wearing off in a matter of hours; and small injections of hypertonic saline into the soft tissue between vertebrae produces local pain that radiates into the phantom limb for ten minutes or so and may be followed by hours, weeks or even longer of partial or total relief from phantom pain. Vigorous vibration or electrical stimulation of the stump, or current from electrodes surgically implanted onto the spinal cord, all produce relief in some patients. Mirror box therapy produces the illusion of movement and touch in a phantom limb which in turn may cause a reduction in pain. Paraplegia, the loss of sensation and voluntary motor control after serious spinal cord damage, may be accompanied by girdle pain at the level of the spinal cord damage, visceral pain evoked by a filling bladder or bowel, or, in five to ten per cent of paraplegics, phantom body pain in areas of complete sensory loss.

Medicine-assisted manipulation, such as manipulation under anesthesia, involves sedation or local anesthetic and is done by a team that includes an anesthesiologist; a 2008 systematic review did not find enough evidence to make recommendations about its use for chronic low back pain. Lumbar, cervical and thoracic chiropractic spinal manipulation Many other procedures are used by chiropractors for treating the spine, other joints and tissues, and general health issues. The following procedures were received by more than one-third of patients of licensed US chiropractors in a 2003 survey: Diversified technique (full-spine manipulation; mentioned in previous paragraph), physical fitness/exercise promotion, corrective or therapeutic exercise, ergonomic/postural advice, self-care strategies, activities of daily living, changing risky/unhealthy behaviors, nutritional/dietary recommendations, relaxation/stress reduction recommendations, ice pack/cryotherapy, extremity adjusting (also mentioned in previous paragraph), trigger point therapy, and disease prevention/early screening advice. A 2010 study describing Belgium chiropractors and their patients found chiropractors in Belgium mostly focus on neuromusculoskeletal complaints in adult patients, with emphasis on the spine.
