  ABSTRACT: Background: Although several treatment strategies to enhance the efficacy of electroconvulsive therapy (ECT) have been discussed, there have been no reports on the combined use of these treatments. The purpose of this study was to evaluate the efficacy and safety of concurrent use of moderate hyperventilation and a reduced dose of propofol combined with divided remifentanil in ECT practice. Methods: Sixty patients scheduled to receive a total of 300 ECT treatments were randomly assigned to have the three interventions: a standard dose (1 mg/kg) of propofol (group P/N); a standard dose of propofol and moderate hyperventilation with end-tidal pressure of carbon dioxide (ETCO2) of 30 - 35 mmHg (group P/H); and a reduced dose (0.5 mg/kg) of propofol with divided supplemental remifentanil and moderate hyperventilation (group RP/H). Patients in group RP/H received remifentanil 1 μg/kg followed by propofol 0.5 mg/kg for unconsciousness and thereafter remifentanil 1 μg/kg immediately before the ECT stimulus. Results: Patients in group RP/H showed significantly longer durations of electroencephalographic (EEG) seizures in the early phase of ECT course (P
