title: Arterial blood-gas analyses during electroconvulsive therapy in a parturient.
abstract: Arterial blood gases and vital signs were monitored in a patient receiving electroconvulsive therapy (ECT) during the third trimester of pregnancy. Alterations in blood pressure and heart rate were similar to those noted in prior studies. Pretreating with 100 percent oxygen (02) and assisting ventilation until return of adequate spontaneous respirations, prevented hypoxemia, significant hypercarbia, and cardiovascular changes. The administration of succinylcholine prevented the systemic manifestations of the electrically-induced seizure. One fetal arrhythmia occurred, apparently unrelated to changes in maternal Pa02, and resolved spontaneously. This technic of anesthesia would appear to be acceptable for ECT in the parturient.
