The use of intravenous lipid emulsion (IVLE) has been proposed as a new potential treatment for local anesthetic toxicity. Local anesthetics work through reversible binding at sodium channels, and signs and symptoms of toxicity include central nervous system and cardiovascular effects. Cardiovascular collapse is a potential result of local anesthetic toxicity, and is generally resistant to resuscitation efforts with standard measures. ⋯ IVLE has shown to be an interesting prospect for local anesthetic toxicity. Human case reports have shown successful resuscitation with use of IVLE, using varying dosing regimens. More studies are needed to determine the optimal dosing regimen, as well as to determine the potential adverse effects of IVLE when used in this setting.
