Endosulfan induced cardiac arrest treated with intravenous lipid emulsion.

OBJECTIVE: Endosulfan is an organochlorine pesticide with high lipophilic features that makes it a well-absorbed agent and penetrates easily to the site of action. Endosulfan toxicities may result in disastrous complications and have high rates of mortality. Several case reports and some researchs discuss the evidence supporting intravenous lipid emulsion (ILE) therapy as a rescue therapy in lipophilic agents' toxicity.

CASE REPORT: A 33-years-old healthy woman with  a history of endosulfan ingestion of uncertain quantity in a suicide attempt six hours ago was admitted to our emergency department. Cardiac arrest ensued after one hour of admission. Cardiopulmonary resuscitation was initiated in accordance with advanced cardiac life support (ACLS) algorithm for asystole. During resuscitation, 2 mL/kg bolus of 20% intravenous lipid emulsion (ILE) was administered for three times at five-minute intervals in addition to ACLS guidance. Spontaneous circulation returned after twenty minutes of resuscitation. No additional antidotal or vasopressor therapies were required during the hospital course of the patient. To our knowledge, this is the first reported case with responded use of ILE treatment for endosulfan toxicity.

CONCLUSION: This case report indicates that ILE treatment should be considered for life-threatening endosulfan intoxications.
