Coagulation and anticoagulation in the intraoperative setting.

ABSTRACT

Adequate function of the coagulation system is vital for an uncomplicated outcome of surgery. Clinically relevant perioperative bleeding complications may occur when surgical hemostasis is inadequate, but can also be caused by insufficient activity of the hemostatic system. Optimal surgical hemostasis and a satisfactory function of the coagulation system are complementary. In this article current insights on normal function and dysfunction of the coagulation system are reviewed as well as drugs that may affect a proper hemostatic response. We discuss coagulation disorders resulting in increased perioperative blood loss and conditions that may enhance the threat of postoperative thrombosis.
