When epinephrine is mixed with local anesthetics, such as bupivacaine or lidocaine, and used for local anesthesia or intrathecal injection, it prolongs the numbing effect and motor block effect of the anesthetic by up to an hour. [45] Epinephrine is frequently combined with local anesthetic and can cause panic attacks. [46]
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 ...
However its use in low dose with local anesthetic administration is warranted. The epinephrine causes vasoconstriction which in turn reduces systemic distribution of the anesthetic as well as prolongs its action in addition to decreasing bleeding at the operating site. Lidocaine 2% with 1:100,000 adrenaline is the local anesthetic of choice in ...
Tumescent anesthesia is a surgical technique for delivery of local anesthesia. It also makes the target tissue firm and turgid from absorbed water, which can aid certain procedures. It was originally devised for use in liposuction, but has since been applied to other surgical situations, including plastic surgery, burn care, and vascular surgery.

Leaves of the coca plant (Erythroxylum novogranatense var. Novogranatense), from which cocaine, a naturally occurring local anesthetic, is derived [1] [2]. 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.
Following a negative aspiration for blood, 2–4 mLs of local anesthetic solution is injected and the needle is withdrawn. 2% Lidocaine (Xylocaine) and 0.5% to 0.75% bupivicaine (Marcaine) are two commonly used agents. Epinephrine, commonly mixed in with local anesthetics for vasoconstriction, is not used in seeing eyes as this can cause a ...
The wait time and isolation of blood flow from the region is important for avoiding an overdose of the anesthetic agent in the blood which can lead to hypotension, convulsions, arrhythmia, and death. Cardiotoxic local anesthetic agents like bupivacaine and etidocaine are strictly contraindicated. [1] [2] [7]
