Effect of divided supplementation of remifentanil on seizure duration and hemodynamic responses during electroconvulsive therapy under propofol anesthesia

Purpose Although a reduced dose of propofol combined with remifentanil is often used in anesthesia for electroconvulsive therapy (ECT), there have been few studies in which the optimal technique for injection of remifentanil was examined in detail. The aim of this study was to evaluate the effects of single and divided injection of remifentanil combined with propofol on seizure duration and hemodynamic responses during ECT.
