Postpartum hemorrhage (defined as >500 mL blood loss after birth by the WHO and >1000 mL blood loss within 24 hours of birth by ACOG), accounts for 27% of maternal deaths worldwide. It is the leading cause of maternal complications and death worldwide, with approximately 70,000 deaths globally.

In a randomized trial published in the NEJM in 2023, they implemented a bundle of first-response treatments including uterine massage, uterotonic medications, and tranexamic acid and compared this intervention group with a control group providing "usual care". They concluded that early detection of PPH and use of bundled treatment led to a lower risk of postpartum hemorrhage, lower need for laparotomy for bleeding, or lower risk of death from bleeding compared with usual care amongst patients having a vaginal delivery.  

This study confirms the already widely-published recommendations for prevention of PPH with active management of the third stage of labor using prophylactic uterotonic medication (most commonly Oxytocin), uterine massage for atony, early cord clamping, and controlled cord traction for delivery of the placenta. Prompt escalation to more aggressive management (including blood transfusion, TXA, and more invasive treatments such as uterine tamponade or surgical intervention) should occur when initial treatments fail.
