Hemoglobin-based oxygen carrier (HBOC-201) and escalating doses of recombinant factor VIIa (rFVIIa) as a novel pre-hospital resuscitation fluid in a swine model of severe uncontrolled hemorrhage.
Exsanguinating hemorrhage and unavailability of blood are major problems in pre-hospital trauma care. We investigated if combining rFVIIa with HBOC-201 reduces blood loss and improves physiologic parameters compared to HBOC alone. Swine underwent liver injury and were resuscitated with HBOC-201 alone or HBOC+90, 180 or 360 μg/kg rFVIIa before hospital arrival at 240 min; animals survived to 72 hours. Blood loss was reduced; MAP, CI, transcutaneous oxygen saturation, and 72-hour survival improved in the 90 and 180 μg/kg rFVIIa groups. Lactate was cleared faster in the HBOC+rFVIIa 90 μg/kg group. Verification in a large, well-powered study is indicated.
