Efficacy of electroconvulsive therapy after propofol and methohexital anesthesia

Fifty-eight patients with major depression were randomly assigned to receive a hypnotic dose of either propofol or methohexital for their complete treatment series of electroconvulsive therapy (ECT). As expected, seizure duration was significantly shorter with propofol than with methohexital anesthesia. Both groups recovered from their depression at the same rate. There was a significant improvement in the Hamilton Rating Scale for Depression scores between the first and last ECT session. However, this was independent of the choice of propofol or methohexital as the anesthetic. This study supports previous reports that seizure duration does not influence recovery from depression.
