We are unable to make any evidence-based treatment recommendation about the use of IV lipid emulsion to treat toxin-induced cardiac arrest. Values, Preferences, and Task Force Insights Although there are many case reports and case series of patients who were resuscitated after administration of IV lipid, the absence of any comparative data made it impossible to determine anything besides temporal association of the therapy with outcome. Despite the paucity of data, we do not wish to discourage the use of an antidote with some theoretical basis in a dire clinical situation.
