Abstract

Intravenous lipid emulsion (ILE) has been suggested as a potential universal antidote for cardiovascular and central nervous system toxicity resulting from a multitude of pharmaceutical and nonpharmaceutical poisonings. While there is some evidence to suggest that ILE may have a positive effect in cardiovascular system toxicity after accidental intravenous lipophilic local anaesthetic overdose, this cannot be extrapolated to cases of severe poisoning resulting from oral drug overdose. Treatment recommendations are based upon variable outcome animal studies and low-level clinical evidence with a significant degree of positive reporting bias. Currently, there is a paucity of controlled clinical data to support ILE use to treat severe drug poisoning after oral overdose. ILE use should be limited to well-designed, ethically approved, controlled clinical trials aimed at determining the true effectiveness of this therapy. This should replace the current scattergun clinical use in a multiplicity of poisoning scenarios and subsequent anecdotal reporting approach.

Keywords: cardiac arrest; cardiovascular; extracorporeal membrane oxygenation; intravenous lipid emulsion; local anaesthetics; overdose; poisoning.
