Postpartum hemorrhage is defined by the amount of blood loss that signals a clinically significant bleed. After cesarean delivery, the threshold is higher because surgical blood loss is expected to be more than after a vaginal birth. Therefore, postpartum hemorrhage after a cesarean is defined as blood loss exceeding 1000 milliliters. This distinguishes it from vaginal deliveries, where the usual cutoff is 500 mL. The other numbers aren’t standard benchmarks for cesarean PP hemorrhage, and relying on them could miss hemorrhages that need prompt intervention. Keep in mind that estimating blood loss can be imperfect, so clinical signs of ongoing bleeding and hemodynamic instability are also critical cues.
