Introduction: Electroconvulsive therapy (ECT) is a well-established psychiatric treatment in which seizures are electrically induced in patients for therapeutic effects. ECT can produce severe disturbances in the cardiovascular system and a marked increase in cerebral blood flow and intracranial pressure. These cardiovascular changes may be altered using various anesthetic drugs. Aim and Objectives: This study was undertaken to compare the effects of intravenous (IV) sodium thiopentone, propofol, and etomidate, used as IV anesthetic agents in modified ECT as regards, induction time and quality of anesthesia, alteration of hemodynamics, seizure duration, and recovery time. Materials and Methods: A total of 90 patients in the age group of 16–60 years of either sex, who had to undergo ECT therapy were divided randomly into three equal groups. Group A received propofol 1% - 1.5 mg/Kg, Group B received etomidate - 0.2 mg/Kg, and Group C received thiopentone 2.5% - 5 mg/Kg. All the patients were monitored for changes in heart rate, systolic blood pressure, diastolic blood pressure, and oxygen saturation at basal, after induction and 1 min, 2 min, 3 min, 5 min, 10 min, 20 min, and 30 min following ECT. Quality of anesthesia, seizure duration, and recovery times were also recorded. Conclusion: We found that propofol had the advantage of smooth induction, stable hemodynamic parameters and rapid recovery as compared to etomidate and thiopentone. Thiopentone had the advantage over propofol of having longer seizure duration at the cost of a relatively prolonged recovery period. Etomidate had a definite advantage of longer seizure duration.
