Objective. This study compares the data of (modified) electroconvulsive theraphy (ECT) applications from two different inpatient clinics in Turkey: Kocaeli Derince Training and Research Hospital (Clinic-I) and Kocaeli University (Clinic-II). Methods. Recorded files of patients from the two clinics were compared in terms of ECT indications, number and duration of seizures, and anesthetic agents used (propofol vs. thiopental). ECT applications occurring between January 2011 and January 2013 were included in the study. Results. A total of 86 patients (9.5% of the inpatients) received ECT in Clinic-I and 103 patients (21.1% of the inpatients) in Clinic-II during the period studied. The yearly ECT rate (treated person rate per 10,000 per year) was 0.59/10,000 for Kocaeli (Turkey) as a whole. The overall number of ECT applications was 539 in Clinic-I and 999 in Clinic-II, and the average number of ECT sessions for each patient was 6.4 +/- 2.33 in Clinic-I and 9.69 +/- 4.66 in Clinic-II. The majority of indications were depressive disorders and insufficient response to medicine. Patients in the clinic which utilized thiopental as the anesthetic agent experienced more cardiovascular and respiratory side effects than the one which used propofol. The number of ECT sessions required was greater for patients with schizoaffective disorder than for others. Conclusions. The administration of ECT was considered to be a reliable method of treatment in these clinics. With respect to specific anesthetic agents, propofol was found to have less hemodynamic side effects and shorter seizure durations than thiopental.
