Abstract
Purpose :
This study was aimed to investigate the clinical efficacy of recombinant activated factor VII (rFVIIa) for patients with intractable postpartum hemorrhage.
Methods :
This was a retrospective study of ten patients who were treated with rFVIIa from July 2010 to February 2012 in one tertiary center. To evaluate each case, we used a standardized case record form. The primary outcome measures were response of rFVIIa, reduction of blood product requirement, changes of coagulation parameter. The response of rFVIIa was categorized to three groups: “complete responder”, “partial responder”, “poor responder”.
Results :
After the administration of rFVIIa, effect for bleeding was completely responded in 4 patients, partially responded in 6 patients, and poorly responded in none. A certain amount of reduction in blood product requirements was noted following rFVIIa administration, although no significant differences were observed statistically between before and after rFVIIa administration except RBC (P<0.01). Fibrinogen and INR were significantly reduced in all case types, but other coagulation parameters were not (P<0.01).
