Multiple-monitored electroconvulsive therapy: safety and efficacy in elderly depressed patients

Forty-four patients with severe endogenous depression, all of whom had been administered multiple-monitored electroconvulsive therapy (MMECT), were studied by retrospective chart review. The subjects were divided into two groups, the elderly and the nonelderly, and compared for number of anesthesia inductions (treatment sessions), total number of seizures, total seizure time, and therapeutic outcome. One myocardial infarction occurred in an elderly man, and a confusional state developed whenever MMECT was administered simultaneously with lithium. The conclusions from this project are that MMECT is as safe and efficacious for the elderly as for the nonelderly and that the elderly tolerate many seizures as well as do the nonelderly. While other variables were similar between groups, the overall number of anesthesia inductions in both groups was less than is expected with conventional electroconvulsive therapy.
