Objective:To investigate the effects of propofol and ketamine on seizure duration,hemodynamics,and recovery of electroconvulsive therapy(ECT).Methods:This prospective randomized trial included patients who had undergone ECT under anesthesia.Patients received injection of propofol 1.5 mg/kg i.v.(the propofol group)or ketamine 0.8-1.2 mg/kg i.v.(the ketamine group)during ECT.Seizure duration,hemodynamics,and recovery were recorded and compared between the two groups.Results:This trial included 44 patinets with 22 patients receiving propofol and 22 patients receiving ketamine.The total dose of propofol and ketamine was(105.68±25.27)mg and(81.36±24.55)mg,respectively.The motor seizure and electroencephalogram seizure duration were prolonged in the ketamine group(P0.05);however,the mean systolic blood pressure during the procedure was significantly higher in the ketamine group(P=0.04).Besides,spontaneous eye-opening in the ketamine group took longer than that of the propofol group(P=0.001).Conclusion:Both propofol and ketamine are safe as anesthetic agents for modified ECT,and ketamine provides a longer seizure duration without hemodynamic instability or any significant complication.
