Whole Blood Administration for Obstetric-Related Hemorrhage During Prehospital Transport.

Abstract

Whole blood transfusion has been used for resuscitation in trauma patients; however, case reports of whole blood transfusion for obstetric-related hemorrhage are limited. Whole blood transfusion typically is accomplished with low titer O-positive whole blood, and, despite success in trauma, use in persons with childbearing potential is of concern due to risk of alloimmunization. We present a case series of patients who received low titer O-positive whole blood for obstetric hemorrhage. One patient was Rh-negative and received immune globulin treatment after whole blood transfusion. All patients survived to hospital discharge. None experienced transfusion-related complications. Whole blood can be successfully administered both in and out of the hospital setting, even for obstetric hemorrhage. The benefits of easily administered balanced resuscitation, limited donor exposure, and improved patient outcomes likely outweigh potential alloimmunization, especially in resource-limited settings. Addressing concerns of alloimmunization cannot be accomplished without more research, and we encourage others to investigate using whole blood in this population.
