Randomized Controlled Trial Multicenter Study
Efficacy and safety of repeated perioperative doses of recombinant factor VIIa in liver transplantation.
Patients undergoing orthotopic liver transplantation (OLT) have excessive blood loss during surgery that requires blood transfusions, leading to increased postoperative morbidity and mortality. We studied the efficacy and safety of activated recombinant factor VII (rFVIIa) in reducing transfusion requirements in OLT. This multicenter, randomized, double-blind, placebo-controlled trial enrolled patients undergoing OLT because of cirrhosis (Child-Turcotte-Pugh class B or C). ⋯ Additionally, there was no statistically significant effect of rFVIIa treatment on hospitalization rate, total surgery time, and the proportion of patients undergoing retransplantation. In conclusion, use of rFVIIa during OLT significantly reduced the number of patients requiring RBC transfusion. There was no increase in thromboembolic events with rFVIIa administration compared with placebo.

Randomized Controlled Trial Multicenter Study
Safety and efficacy of a single bolus administration of recombinant factor VIIa in liver transplantation due to chronic liver disease.
Orthotopic liver transplantation (OLT) can be associated with excessive blood loss. As a result, there may be increased risk of adverse outcomes. Activated recombinant factor VII (rFVIIa) has demonstrated the ability to improve hemostasis in a variety of disorders; however, there has been a limited amount of research into its use in OLT. ⋯ The number of adverse events was comparable between study groups. In conclusion, rFVIIa has a good safety profile in patients undergoing OLT. However, the doses studied did not have any effect on the number of RBC transfusions required.
