Mild Anemia and Risk of Postpartum Hemorrhage or Blood Transfusion in Preeclampsia

Abstract

In risk stratification toolkits, the combination of moderate anemia (hemoglobin < 10.0 g/dL) and use of magnesium sulfate is considered high risk for postpartum hemorrhage (PPH) and blood transfusion. Magnesium sulfate may be a proxy for preeclampsia (PE) with severe features. However, mild anemia (hemoglobin 10.0-10.9 g/dL) may also increase risk for PPH and transfusion in the setting of preeclampsia.
