Multicenter Study
Clinical experience with intravenous lipid emulsion for drug-induced cardiovascular collapse.
Intravenous lipid emulsion (ILE) is an emerging therapy for refractory cardiotoxicity due to lipid-soluble drugs. The purpose of this study was to assess survival to hospital discharge, effects on hemodynamic parameters, and adverse event occurrence for patients who were treated with ILE as part of the resuscitative effort for drug-induced cardiotoxicity. This is a multicenter retrospective chart review of inpatients at three tertiary referral medical centers receiving ILE for drug-induced cardiotoxicity between November 2007 and March 2009. ⋯ Adverse events due to ILE therapy that were categorized as "possible" or "probable" based on Naranjo scores included lipemia, digit amputation, lung injury, renal failure, and deep venous thrombosis. ILE administered to patients with drug-induced cardiovascular collapse was associated with 55% survival but with clinically significant adverse effects. At this time, ILE should be restricted to cardiotoxicity involving cardiac arrest or refractory shock until further prospective studies can better evaluate risks and benefits of ILE therapy.
