Updates in the perioperative management of postpartum hemorrhage

Abstract

BackgroundPostpartum hemorrhage (PPH) is the leading cause of maternal death all over the world. It could be primary or secondary with uterine atony being the cause in 80% of cases.Main bodyFor anticipated PPH, special antenatal preparation for abnormal placentation, inherited coagulation disorders, and Jehovah’s Witnesses must be done. Optimal surgical management of placenta accreta is done by scheduling delivery in an appropriate surgical facility, by insertion of prophylactic embolization catheters in the uterine or internal iliac arteries, and by rapid diagnosis of PPH. The obstetric shock index (SI) is highly specific for PPH. Optimal anesthetic management is done by oxygen supply, using warming devices, ensuring wide bore intravenous (IV) access with adequate volume replacement, and blood product preparation. The non-pneumatic anti-shock garment (NASG) could be used as first-aid compression device. Permissive resuscitation, uterotonic administration, tranexamic acid, recombinant active factor seven (VIIa), and lyophilized fibrinogen concentrate are beneficial. Hemostatic reanimation to correct coagulopathy and cell saver auto-transfusion are applied. For unanticipated PPH, guidelines and regular skill training reduce the incidence of severe PPH.ConclusionsAnticipated PPH requires antenatal preparation, optimal anesthetic management with the implementation of permissive resuscitation, hemostatic reanimation, and optimal surgical management.
