title: [Anesthesia for electroconvulsive therapy during pregnancy--a case report].
abstract: We experienced anesthetic management for ECT in a patient with psychiatric disease during the third trimester of pregnancy. The 24 year-old patient had been on oral antipsychotics prescribed to treat schizophrenia for ten years. Her signs and symptoms deteiorated during pregnancy in spite of increased doses of antipsychotics. With tocolytic agent administered intravenously, anesthesia was induced by intravenous thiamylal immediately followed by intravenous suxamethonium for muscle relaxation. Alternative current was applied on both side of the head after the sufficient anesthesia had been obtained. The patient received intermittent mandatory ventilation by breathing mask with 100% oxygen during the procedure. Along with monitoring of maternal hemodynamic variables and arterial oxygen saturation (Spo2), fetal heart rate and uterine contraction were recorded by cardiotocogram throughout the procedure. At the first two treatments, the patient showed neither significant uterine contraction nor fetal heart rate changes. At the third treatment, continuous uterine contraction refractory to tocolysis was recorded for six minutes, resulting in fetal bradycardia. At the sixth treatment, general anesthesia was induced and maintained by sevoflurane in oxygen followed by suxamethonium for muscle relaxation. The uterine contraction was remarkably diminished and fetal heart rate remained unchanged during the procedure. In conclusion, inhalation anesthesia is beneficial for ECT in the last stage of pregnancy to reduce uterine contraction by potential uterine relaxation effect of anesthetics.
