Bloodless reperfusion with the oxygen carrier HBOC-201 in acute myocardial infarction: a novel platform for cardioprotective probes delivery.

Reperfusion, despite being required for myocardial salvage, is associated with additional injury. We hypothesize that infarct size (IS) will be reduced by a period of bloodless reperfusion with hemoglobin-based oxygen carriers (HBOC) before blood-flow restoration. In the pig model, we first characterized the impact of intracoronary perfusion with a fixed volume (600 ml) of a pre-oxygenated acellular HBOC, HBOC-201, on the healthy myocardium.

A safety and efficacy evaluation of hemoglobin-based oxygen carrier HBOC-201 in a randomized, multicenter red blood cell controlled trial in noncardiac surgery patients.

Background: We present the results of a previously unpublished hemoglobin-based oxygen carrier (HBOC) study conducted in 1998-1999.

Methods: In a multicenter, randomized, single-blind, comparative study of HBOC-201 versus allogeneic red blood cell (RBC) transfusions, no-cardiac surgery patients received HBOC-201 to a maximum of 7 units (n = 83) or RBCs (n = 77). Patients could be switched to RBCs for safety or any other reason.
