Despite initial excitement for the use of intravenous lipid emulsion (ILE) therapy as an antidote for serious poisonings due to lipohphilic drugs there remains an absence of evidence combined with an incomplete understanding of its efficacy, mechanisms of action, safety, and analytical interferences to recommend its use except in a few clinical scenarios.
The lipid emulsion workgroup performed a comprehensive analysis of four systematic reviews and based recommendations from consensus of expert panelists from the American Academy of Clinical Toxicology, the European Association of Poison Centres and Clinical Toxicologists, the American College of Medical Toxicology, the Asia Pacific Association of Medical Toxicology, the American Association of Poison Control Centers, and the Canadian Association of Poison Control Centers. Toxins evaluated had to have a minimum of three human cases reported in the literature.They concluded that ILE could be indicated for the following clinical situations:
The Bottom Line:
The use of Intravenous Lipid Emulsion in severe poisoning is recommended only for a few poisoning scenarios and was based on very low quality of evidence, and consideration of risks and benefits, adverse effects, laboratory interferences as well as related costs and resources.
