Background:
Hemorrhagic shock is a clinically challenging disease process with high mortality. When conventional blood products are unable to be administered, oxygen-carrying blood alternatives are sometimes utilized. The international experience with this scenario is limited. We aim to add to this body of literature.
Study Design And Methods:
This is a case report of the administration of bovine hemoglobin-based oxygen-carrying red blood cell (RBC) substitute HBOC-201 (HemoPure®) to a patient with post-partum bleeding and hemorrhagic shock because the patient declined RBC transfusion. HBOC-201 was administered with consent under a one-time Emergency Investigational New Drug (eIND) approval from the Food and Drug Administration with appropriate notification of the Institutional Review Board.
Results:
The patient was successfully resuscitated with HBOC-201 from hemorrhagic shock. She was weaned off of vasopressor support and extubated with the recovery of her baseline mental status within 4 h. However, approximately 36 h after this, the patient developed multi-organ system dysfunction, volume overload, right heart failure and ultimately expired early on post-partum day 4.
Discussion:
Resuscitation from hemorrhagic shock with HBOC-201 as an RBC alternative is feasible, but significant challenges remain with the management of sequelae resulting from prolonged low-flow, ischemic states as well as the significant colloid pressure and volume overload experienced after massive transfusion with an acellular colloid oxygen carrier.
