Outcome of perioperative hemostatic management in patients with hemophilia without inhibitors undergoing 161 invasive or surgical procedures.

Perioperative management of persons with hemophilia (PWH) is a challenge for surgeons and hematologists. Reductions in mortality rate and complications have been achieved since the introduction of clotting factor concentrates (CFCs), which improve hemostatic control. However, there is no clear consensus on the optimal dosing of CFC administration. The aim of this study was to evaluate the outcome of PWH without inhibitors in patients undergoing invasive or surgical procedures. A total of 161 procedures, including 57 major and 104 minor ones were retrospectively reviewed. The characteristics of PWH, age at procedure, duration and total amount of CFC administration during the perioperative period, hemostatic adequacy, and complications were summarized. The study showed a low rate of bleeding (1.2%), infection (0%), thromboembolic event (0%), and inhibitor development (0%). The results revealed the doses and duration of CFC administration for several major and minor procedures which were capable of achieving excellent hemostatic control.
