Recombinant Activated Factor VIIa Use in Massive Transfusion and Coagulopathy Unresponsive to Conventional Therapy

Abstract

We report a retrospective analysis of patients admitted to a tertiary intensive care unit who received recombinant activated factor VIIa (rFVIIa) in an effort to control life-threatening haemorrhage and coagulopathy. Data extracted included: demographics, diagnoses and clinical course, dosage of rFVIIa, blood product requirements and coagulation tests prior to and after rFVIIa, pH, base deficit and temperature. During the study period rFVIIa was given to nine patients with refractory coagulopathy in imminent danger of death. Three patients were post cardiac surgery, three patients had multiple blunt trauma, one patient had a close range shotgun wound to the abdomen, one patient had a ruptured iliac artery aneurysm and one patient was post caesarean section with acute fatty liver of pregnancy. Improvements in prothrombin time (PT) (median 17s pre vs 10.6s post rFVIIa (P < 0.05)) were seen in all nine cases. Reduced requirements for red blood cells, fresh frozen plasma, platelets and cryoprecipitate followed rFVIIa administration in eight cases. One patient died after 48 hours of complications unrelated to the initial pathology. Seven patients were discharged from hospital; one remains in hospital. rFVIIa provided improvement in coagulopathy unresponsive to conventional therapy.
