Modified electroconvulsive therapy (MECT) is a fast and effective physical therapy method currently widely used in psychiatry. The anesthesia target of this treatment is to calm the patients, relax the muscles and maintain stability in histodynamics during treatment, meanwhile avoiding affecting efficacy, because too deep anesthesia can inhibit discharge of the cerebral cortex. However, current anesthetic drugs in MECT, including muscle relaxants, intravenous anaesthetics, inhalation anaesthetics, analgesics, etc., lack the best compatibility of anesthesia induction. This review discusses the application and compatibility of these drugs in MECT in recent years, in order to provide reference for the best anesthesia induction protocol for MECT.
