Purpose: To report our experience with recombinant activated factor VII (rFVIIa) to control hemorrhage in trauma patients with profound multifactorial coagulopathy. rFVIIa forms a complex with tissue factor exposed at sites of tissue damage and induces activation of coagulation limited to the site of injury. It is approved for use in hemophilia patients, however, its use in trauma is still controversial due to the theoretical risk of thromboembolic complications. Clinical features: Nineteen critically ill, multi-transfused patients with trauma (ten blunt and nine penetrating), aged 25 ± 17 yr, were treated with rFVIIa after all conventional hemostatic measures had failed. After one to three doses of rFVIIa, hemorrhaging ceased within minutes in 15/19 (78.9%) patients. The total dose of rFVIIa required to control bleeding was 195 ± 112.7 μg·kg-1. Shortening of prothrombin time and partial thromboplastin time was observed within 15-30 min from 22.7 ± 7.9 to 10.4 ± 2.6 sec and 71 ± 38.9 to 42.2 ± 24 sec respectively, (P < 0.05). Transfusion requirements decreased from 30 ± 18.3 units used within 5.6 ± 3.4 hr of admission to 2.8 ± 2.5 within the following 24 hr (P < 0.05). One patient developed clinical deep vein thrombosis. No systemic activation of coagulation was observed clinically. Thirteen patients (68.4%) survived and recovered. Four patients did not respond to rFVIIa treatment and exsanguinated within 24 hr. Two patients died after one week, one from sepsis and one from multiorgan failure. Conclusions: rFVIIa is a promising adjunctive hemostatic treatment for trauma patients suffering from massive bleeding. Controlled trials are warranted to evaluate the safety and efficacy of this drug.
