Objectives: In this study, the aim was to evaluate the clinical characteristics of patients that received electroconvulsive therapy (ECT) during pregnancy due to psychiatric disorders, evaluate the safety and efficacy of ECT in pregnant women, and evaluate the overall status of mothers and babies during the postpartum period. Methods: The study included 33 patients who were admitted as inpatients with the indication of ECT due to pregnancy and concurrent psychiatric disorders. Results: Upon ECT administration, a complete response to treatment was seen in 84.21% of patients with major depression (n=16), a partial response to treatment in 15.78% of patients (n=3), a complete response to treatment in 91.66% of patients with bipolar disorder (n=11), a partial response to treatment in 8.33% of the patients(n=1), and a full response to treatment in 50% of patients with schizophrenia (n=1) and a partial response to treatment in 50% of patients with schizophrenia (n=1) were obtained. We had after birth information of 27 infants from total 33. It was learned that two of them had disease, one was stillbirth and 24 of them did not have any health problems. Conclusions: ECT administration during pregnancy to treat psychiatric disorders was found to be an effective treatment method. No risk of preterm birth in mothers treated with ECT during pregnancy was detected. (C) 2013 Elsevier Inc. All rights reserved.
