What Is the Initial Treatment of Placental Abruption with Class 1 Hemorrhagic Shock?

This protocol addresses acute placental abruption presenting with an estimated blood loss of less than 15%, consistent with Class 1 hemorrhagic shock. At this stage, the priority is structured maternal stabilization before any consideration of transfusion.

Management begins with securing IV access and initiating fluid resuscitation with crystalloids, combined with urgent laboratory evaluation covering hematologic and coagulation parameters and blood typing. The complete protocol specifies the type of IV access required, which laboratory tests to obtain, a defined cross-matching step, and a structured monitoring schedule — these details are available in the full protocol below.

Response to resuscitation is measured by stabilization of vital signs: a heart rate below 100 bpm and urine output greater than 30 mL per hour.
