In the presence of ongoing blood loss, one must quickly distinguish between surgical bleeding and coagulation derangements. Initially, this risk is assessed preoperatively with several tests assessing different stages of the clotting cascade. However, given the potential for evolving intraoperative derangements, the clotting ability should also be assessed perioperatively as well. Certain surgical procedures require the induction of a coagulopathic state, such as necessitating the use of extracorporeal blood flow machines.
