Application of etomidate mixed with propofol during modified electroconvulsive therapy (MECT) in schizophrenics with hypertension / 实用医学杂志

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.
