Background and Aims: Modified electroconvulsive therapy is routinely used to treat complicated psychiatric disorders. Its therapeutic effect is directly proportional to induced seizure duration but it is associated with hemodynamic disturbances. The aim of this study was to evaluate the effect of a ketamine + propofol combination (“ketofol”) for electroconvulsive therapy and to compare these with the effects of propofol alone. Methods: In this prospective study, 60 patients aged 18–60 years with American Society of Anesthesiologists (ASA) Ι and ΙΙ for psychiatric disorders were included. Patients were divided into two groups (30 each). Group P received propofol at 10 mg/ml and group K received ketofo at 10 mg/ml (ketamine 5 mg/ml and propofol 5 mg/ml in a 1:1 ratio). Motor/electroencephalography (EEG) seizure duration, induction time, hemodynamic variables, recovery time, agitation score, and complications were recorded. Standard qualitative and quantitative tests were used to compare the data (e.g., unpaired student t-test, Chi-squared test, etc). A P value of < 0.05 was considered to be significant. Results: The mean duration of (motor/EEG) seizure was statistically significantly high in the ketofol group compared to the propofol group (P = 0.0001/0.0001). The mean induction time was significantly less in the ketofol group compared to propofol group (P = 0.0001). The recovery time was significantly early in group K patients compared to group P (P = 0.004). The ketofol group was more hemodynamically stable with comparable agitation score and side effects than patients in the propofol group. Conclusion: In modified ECT, ketofol was associated with longer seizure duration, lesser induction time, better hemodynamic stability, early recovery with comparable post ECT agitation and adverse effects compared to propofol alone.
