Intravenous lipid emulsion for local anesthetic toxicity: A review of the literature

Introduction 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.
