Intraoperative Management of Revealed Placental Abruption

Initial Recognition and Resource Mobilization

The American College of Obstetricians and Gynecologists recommends immediate implementation of a systematic hemorrhage management protocol, including rapid mobilization of blood products in a 1:1:1 ratio of packed red blood cells, fresh frozen plasma, and platelets, while simultaneously proceeding with definitive surgical management 1, 2
Establish additional large-bore intravenous access for rapid fluid and blood product administration, as recommended by the American Journal of Obstetrics and Gynecology 4
Activate massive transfusion protocol early rather than waiting for laboratory results, as suggested by the American Journal of Obstetrics and Gynecology 1

Transfuse blood products in a fixed ratio (1:1:1 to 1:2:4) of packed red blood cells:fresh frozen plasma:platelets, as recommended by the American Journal of Obstetrics and Gynecology 1, 5
Consider administration of tranexamic acid to reduce blood loss, as suggested by the American Journal of Obstetrics and Gynecology 2
Maintain patient temperature above 36°C as clotting factors function poorly at lower temperatures, as recommended by the American College of Obstetricians and Gynecologists 6

If placental abruption is accompanied by placenta accreta spectrum, avoid attempts at forced placental removal which can trigger profuse hemorrhage, as recommended by the American Journal of Obstetrics and Gynecology 4, 6
For cases with extensive placental involvement and ongoing hemorrhage, proceed with hysterectomy as judiciously as possible, as suggested by the American Journal of Obstetrics and Gynecology 4, 5

If the center lacks appropriate resources for definitive management, consider stabilization and transfer (if patient is stable), as recommended by the American Journal of Obstetrics and Gynecology 2, 3
Mobilize appropriate resources concurrently with ongoing surgical management, as suggested by the American Journal of Obstetrics and Gynecology 2

Plan for intensive hemodynamic monitoring in the early postoperative period, preferably in an ICU setting, as recommended by the American Journal of Obstetrics and Gynecology 1, 8
Maintain vigilance for ongoing bleeding with a low threshold for reoperation if suspected, as suggested by the American Journal of Obstetrics and Gynecology 8

Delaying activation of massive transfusion protocol can worsen outcomes; initiate early, as recommended by the American Journal of Obstetrics and Gynecology 1, 3
Attempting forced placental removal when placenta accreta is present can lead to catastrophic hemorrhage, as suggested by the American Journal of Obstetrics and Gynecology 4, 6
Inadequate surgical expertise may worsen outcomes; pause the case to mobilize appropriate expertise if needed, as recommended by the American Journal of Obstetrics and Gynecology 4
