ABSTRACT
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.
ABSTRACT
Objective To compare the treatment accomplishmentsand adverse effects of the mixed- or single-application of etomidate and propofol during modified electroconvulsive therapy (MECT) in schizophrenics with hypertension. Methods Ninety hospitalized schizophrenics with hypertension undergoing MECT were ran-domly assigned to 3 groups: Group EP(etomidate = 0.3 mg/kg and propofol = 1.0 mg/kg), Group E (etomi-date = 0.7 mg/kg) and Group P (propofol = 2.0 mg/kg). Changes of SBP, DBP and HR were recorded before anesthesia, after induction, electrical stimulation instantly and 5 min after electrical stimulation. The average pe-riods of epileptic seizure (ESD), postictal suppression index (PSI) and the adverse reactions were also recorded. Results The ESD and PSI scores were significantly higher in Group EP and Group E than those in Group P (P < 0.05). SBP and DBP in Group E were significantly higher at the electrical stimulation instant than those af-ter induction (P < 0.05). SBP and DBP in Group P were significantly lower after induction than those before anesthesia(P < 0.05). The injection pain of Group EP and Group E were lower than that of Group P(P < 0.05). No significant differences were found among 3 groups in the adverse reactions such as nausea/vomiting anddys-phoria.Conclusion The mixed liquor of etomidate and propofol can extend the time of seizure, reduce the nega-tive reaction of cardiovascular system and adverse reactions during MECT in schizophrenics with hypertension.
