Randomized Controlled Trial Clinical Trial
Hypotensive resuscitation using a polymerized bovine hemoglobin-based oxygen-carrying solution (HBOC-201) leads to reversal of anaerobic metabolism.
Traditional resuscitation regimens have been recently challenged. This study evaluates hypotensive resuscitation with a hemoglobin-based oxygen-carrying (HBOC) solution after severe hemorrhage in a porcine model. We hypothesized that HBOC-201 restores tissue perfusion at a lower mean arterial pressure than standard resuscitation fluids. ⋯ Hypotensive resuscitation with HBOC-201 at a MAP of 60 mm Hg after a controlled hemorrhage in swine provides sufficient tissue perfusion and oxygen delivery to reverse anaerobic metabolism on the basis of global physiologic markers despite continued hypotension, hypovolemia, and low cardiac output.
