Abstract

<abstract abstract-type="main" id="jth12844-abs-0001"> <title>Summary</title> <sec id="jth12844-sec-0001" sec-type="section"> <title>Background</title> <p>Case reports on recombinant human factor VIIa (rhuFVIIa) use in women with severe postpartum hemorrhage (PPH) showed encouraging results, but no randomized controlled trial (RCT) is available.</p> </sec> <sec id="jth12844-sec-0002" sec-type="section"> <title>Patients and methods</title> <p>Eighty‐four women with severe PPH unresponsive to uterotonics were randomized to receive one early single rhuFVIIa infusion (<italic>n</italic> = 42) or standard care (no rhuFVIIa; <italic>n</italic> = 42). The primary efficacy outcome measure was the reduction of the need for specific second‐line therapies, such as interventional hemostatic procedures, for blood loss and transfusions. The primary safety outcome measure was the number of deaths and thrombotic events during the 5 days following rhuFVIIa infusion.</p> </sec> <sec id="jth12844-sec-0003" sec-type="section"> <title>Results</title> <p>rhuFVIIa was associated with a reduction in the number of patients who needed second‐line therapies compared with controls (standard care). Specifically, 39/42 (93%) patients in the standard care arm received second‐line therapies and 22/42 (52%) patients in the rhuFVIIa arm (absolute difference, 41%; range, 18–63%; relative risk RR, 0.56 [0.42–0.76]). The delivery mode (vaginal or Cesarean section) did not affect the primary outcome. No death occurred. Two venous thrombotic events were recorded in the rhuFVIIa arm: one ovarian vein thrombosis and one deep vein thrombosis with a non‐severe pulmonary embolism.</p> </sec> <sec id="jth12844-sec-0004" sec-type="section"> <title>Conclusion</title> <p>This open RCT in women with severe PPH refractory to uterotonics shows that rhuFVIIa reduces the need for specific second‐line therapies in about one in three patients, with the occurrence of non‐fatal venous thrombotic events in one in 20 patients.</p> </sec> </abstract>
