How much blood loss is defined as postpartum hemorrhage after a cesarean delivery?

Postpartum hemorrhage (PPH) is defined as abnormal or excessive bleeding following childbirth. For cesarean deliveries, the definition of PPH is specifically set at a blood loss of 1,000 mL or more. This threshold acknowledges that cesarean deliveries typically involve greater blood loss due to the surgical nature of the procedure.

Understanding this definition is crucial for timely recognition and intervention of PPH, which is a significant cause of maternal morbidity and mortality. Identifying the threshold as 1,000 mL helps healthcare providers establish protocols for monitoring and managing blood loss effectively in the postpartum period.
