Brief Summary
There is a paucity of data on management of non-acute postpartum anemia. Although blood transfusions were historically initiated with 2 units, the most recent recommendation from the American Association of Blood Banks is to begin with 1 unit. As no randomized controlled trials have been performed in obstetrics, the investigators propose a randomized, controlled trial in non-acute postpartum anemia comparing single- versus multiple-unit transfusion by total numbers of units transfused and maternal morbidity.

Study Arms (2)
Single-Unit Blood Transfusion Protocol
ACTIVE COMPARATORIn this arm, patients receive a 1 unit pRBC transfusion with the plan for post-transfusion blood count at 4-6 hours post-transfusion and clinical reassessment.
Multiple-Unit Blood Transfusion Protocol
ACTIVE COMPARATORIn this arm, patients receive 2 units of pRBCs, followed by 4-6 hour post-transfusion blood count and clinical reassessment.
Interventions
Patients are randomized to receive 1 or 2 units of packed red blood cells for initial transfusion.
