Mechanisms of hemostasis at cesarean delivery.

Postpartum hemorrhage is an obstetric emergency that represents a major cause of maternal morbidity and mortality. With the recent rise in the cesarean delivery rate, prompt recognition and proper management at the time of cesarean delivery are becoming increasingly important for providers of obstetrics. Preparedness for hemorrhage can be achieved by recognition of prior risk factors and implementation of specific hemorrhage protocols. Medical and surgical therapies are available to treat obstetric hemorrhage after cesarean delivery.
