A CASE REPORT OF PROLONGED APNEA DURING ECT IN A PATIENT WITH SUICIDAL ATTEMPT BY ORGANOPHOSPHORUS POISON.

Introduction: Organophosphorus pesticides have been used in some cases for suicidal attempts. Such poison can affect plasma cholinesterase activity. Methods: This case was a 43-year-old man hospitalized due to suicide attempt with swallowing agricultural poison. The patient, diagnosed with major depressive disorder (MDD), underwent treatment with electroconvulsive therapy (ECT). At the first ECT session, the patient developed apnea for 4 hours after receiving 25 mg succinylcholine. Results: The patient was intubated and kept on ventilator support for 4 hrs in ICU; after restoration of respiration depth and rate, the patient was extubated. Conclusion: Collectively, in cases with history of suicide attempts, taking organophosphorus pesticides should be warned for pre-ECT anesthesia.
