Intrauterine Postpartum Hemorrhage-Control Devices

Obstet Gynecol. 2023 Oct 5. doi: 10.1097/AOG.0000000000005403. Online ahead of print.ABSTRACTPostpartum hemorrhage, defined as a cumulative blood loss of 1,000 mL or more or blood loss associated with signs or symptoms of hypovolemia regardless of the route of delivery, is the leading cause of preventable maternal death worldwide. The United States has one of the highest maternal mortality rates among developed countries, with about 14% of all maternal deaths associated with postpartum hemorrhage. Although postpartum hemorrhage has multiple causes, the most common is uterine atony-when the uterus fails to adequately contract after childbirth-accounting for 80% of all postpartum hemorrhages. When postpartum hemorrhage occurs despite preventive measures, therapeutic measures are used. Intrauterine hemorrhage-control devices are often the second-line therapy when medical management is unsuccessful. Despite its widespread use in current obstetric practice, the mechanism of intrauterine balloon tamponade, such as the Bakri balloon, is counterintuitive to the physiologic uterine contraction that occurs after delivery to control bleeding, and data on its effectiveness are mixed. Vacuum-induced hemorrhage control, such as with the Jada System, cleared by the U.S. Food and Drug Administration in 2020, is a novel modality for control of postpartum bleeding. It mimics postpartum physiology by applying low-level intrauterine negative pressure to facilitate uterine compressive forces, the...
