Lidocaine is an antiarrhythmic medication of the class Ib type. [8] This means it works by blocking sodium channels thus decreasing the rate of contractions of the heart. [11] [8] When injected near nerves, the nerves cannot conduct signals to or from the brain. [9] Lidocaine was discovered in 1946 and went on sale in 1948. [12]
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.
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.
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 ...

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.
Cortical spreading depression (CSD) or spreading depolarization (SD) is a wave of electrophysiological hyperactivity followed by a wave of inhibition. [3] Spreading depolarization describes a phenomenon characterized by the appearance of depolarization waves of the neurons and neuroglia [ 4 ] that propagates across the cortex at a velocity of 1 ...
Paracaine, tetracaine, bupivacaine, lidocaine etc. may also be used in place of xylocaine. [1] Cataract surgery by phacoemulsification is frequently performed under surface anaesthesia. Facial nerve, which supplies the orbicularis oculi muscle, is blocked in addition for intraocular surgeries. Topical anaesthesia is known to cause endothelial ...
