Lidocaine's half-life in the body is about 1.5–2 hours. [2] The time it takes for the anesthetic medication to prevent pain in the area (speed of onset) and length of time that the area does not have painful sensations are considerations when choosing an appropriate approach to dental treatment.
Lidocaine is an antiarrhythmic medication of the class Ib type. [7] This means it works by blocking sodium channels thus decreasing the rate of contractions of the heart. [10] [7] When injected near nerves, the nerves cannot conduct signals to or from the brain. [8] Lidocaine was discovered in 1946 and went on sale in 1948. [11]
Overall, the procedure involves injecting a local anesthetic drug (e.g. lidocaine or bupivicaine) with a 20 gauge spinal needle near the pudendal nerve in order to provide pain relief. [1] [2] Lidocaine is usually preferred for a pudendal block because it has a longer duration than chloroprocaine which usually lasts less than one hour. [5]
Rather, it refers to a mixture of viscous lidocaine, an antacid, and an anticholinergic. [1] [2] Viscous lidocaine works as an anesthetic to numb pain in the throat, esophagus, and stomach. Antacids work to neutralize stomach acid. Anticholinergics work to ease symptoms that accompany dyspepsia including nausea, vomiting, and abdominal cramping.
Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...
The most common combination of agents used in tumescent anesthesia is lidocaine (0.05-0.10%) and epinephrine (1 ppm). [3] [4] [5] For lidocaine, total doses of 35 mg/kg [6] and 55 mg/kg [7] have been reported as reasonably safe high-end doses, in the context of liposuction.
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.
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. [1]
