Background: This study evaluated the safety and hemostatic effectiveness of a tranexamic acid- and aprotinin-free fibrin sealant versus an absorbable hemostat in soft tissue during elective retroperitoneal or intra-abdominal surgery. Materials and Methods: This randomized, active-controlled, multicenter study enrolled patients who were undergoing elective retroperitoneal or intra-abdominal surgery and required adjunctive hemostatic measures at the target bleeding site (TBS). Patients were randomized (time = 0 minutes) to receive fibrin sealant or absorbable hemostat. The primary endpoint was the absence of bleeding at the TBS at 10 minutes. Secondary endpoints included the absence of bleeding at 4 and 7 minutes and the incidence of treatment failure (bleeding at 10 minutes or brisk bleeding requiring additional hemostatic measures), and the incidence of complications potentially related to bleeding. Adverse events were assessed. Results: Patients (N = 124) were randomized to receive fibrin sealant (n = 62) or absorbable hemostat (n = 62). A higher percentage of patients who received fibrin sealant versus absorbable hemostat achieved hemostasis within 10 minutes (95.2% vs 82.3%; 95% CI, 1.02-1.35) and also at 4 (74.2% vs 54.8%; 95% CI, 1.04-1.80) and 7 (90.3% vs 77.4%; 95% CI, 1.00-1.39) minutes. A lower incidence of treatment failure was observed for patients receiving fibrin sealant. Similar incidences of adverse events and complications potentially related to bleeding were observed. Conclusions: This tranexamic acid- and aprotinin-free fibrin sealant is safe and effective for achieving hemostasis in soft tissue during elective retroperitoneal or intra-abdominal surgery.
