Purpose: Information on the use of extracorporeal membrane oxygenation (ECMO) in obstetric patients is scarce. The objective was to conduct a systematic review examining ECMO use in pregnant and postpartum patients in order to identify indications leading to ECMO use and to assess mortality rates.

Materials And Methods: PubMed, EMBASE, Cochrane Library, and SCOPUS were searched using the terms "extracorporeal membrane oxygenation" and "pregnancy" up to 1 November 2020. Case reports and case series reporting the use of ECMO in pregnancy were eligible. Data about maternal age, gestational age, diagnosis, type of ECMO, time on ECMO, pregnancy outcomes, and maternal survival were extracted from studies.

Results: The search yielded 1696 citations, of which 125 were included. There were 213 obstetric patients treated with ECMO over a 30-year period. The frequency of reports increased considerably over the last decade. The majority of patients were treated in their third trimester (28.2%) or postpartum (32.9%). Most common etiologies included influenza-induced ARDS (27.7%), pulmonary embolism (13.6%), peripartum cardiomyopathy (11.7%), and infection (11.7%). Pregnancy outcomes ended with live births, either on ECMO (15.5%, 95% CI 10.6-20.4) or not on ECMO (58.3%, 95% CI 51.7-64.9), in fetal demise (8.9%, 95% CI 5.1-12.7), or in spontaneous or induced abortion on ECMO (4.2%, 95% CI 1.5-6.9) or not on ECMO (4.2%, 95% CI 1.5-6.9). Maternal survival was 79.3%.

Conclusion: Although women placed on ECMO had a high mortality rate, this is likely an indication of the severity of illness. Overall, ECMO appears to be a valid therapy for the temporary support of vital organs in severely ill pregnant women.
