Extracorporeal membrane oxygenation application in post-partum hemorrhage patients: Is post-partum hemorrhage contraindicated?

Extracorporeal membrane oxygenation (ECMO) is commonly used in patients who experience circulatory arrest or significant cardiac dysfunction and is associated with improved clinical outcomes. We conducted a retrospective observational study on ECMO application at a single tertiary center over a five-year period. Five patients who suffered post-partum hemorrhage resulting from uterine atony were treated with ECMO. The mean age was 36.8 +/- 3.9 years; the mean gestational age was 37.8 +/- 2.2 weeks; the initial mean maternal hemoglobin level was 5.0 +/- 2.4 mg/dL; and the mean estimated blood loss was 3260 +/- 1545 mL before treatment. All patients were treated with venoarterial ECMO and one was treated with both venoarterial and venovenous ECMO. The mean ECMO usage duration was 32.6 +/- 18.8 h (range 10-54). Four (80%) patients survived until discharge without experiencing neurological sequela. ECMO should not be a contraindication for treatment of post-partum hemorrhage and such patients should be weaned as soon as possible to ensure the early recovery of cardiac function.
