Bleeding is a major surgical complication. Although mortality rates of 0.1% are observed for surgical procedures, it may be 5% to 8% for elective vascular surgery, and increase to 20% in the presence of severe bleeding. In major surgery for liver diseases, as well as in cardiac surgery, excessive blood loss is associated with increased mortality, morbidity, and intensive care stay. Approximately 75% to 90% of intraoperative and early postoperative bleeding is due to technical factors. However, in some cases either acquired or congenital coagulopathies may favor, if not directly cause, surgical hemorrhage. Uncontrolled bleeding leads to a combination of hemodilution, hypothermia, consumption of clotting factors, and acidosis, which in turn worsen the clotting process, further exacerbating the problem in a vicious bloody circle. At present, the standard treatment for surgical bleeding is the rapid control of the source of bleeding by either surgical or radiological techniques. Blood-derived products as well as hemostatic agents, such as aprotinin, tranexamic acid, and DDAVP, are widely used to improve hemostatic balance in bleeding patients. Recombinant activated factor VII (rFVIIa) has been reported to be effective for the treatment of surgical or traumatic massive bleeding unresponsive to conventional therapy. Although most reports are anecdotal, and therefore exposed to a "positive" selection bias, the number of cases is impressive, strongly suggesting that in such patients rFVIIa may afford a hemostatic advantage beyond that of conventional replacement therapy.

In trauma associated coagulopathy, the initial treatment consists of hypothermia and acidosis have to be treated aggressively. Already in in the emergency room, fibrinogen deficiency can be detected frequently, in addition, colloids interfere with fibrin polymerisation. Under these aspects, the early administration of fibrinogen seems to be justified. Depleted coagulation factors can be substituted with PPSB and/or fresh frozen plasma, while in view of a risk of infection, retaining administration of platelet concentrates is indicated. The potential of using haemostatic agents like antifibrinolytics and DDAVP for this indication is only supported by few studies, although in individual cases it may be very helpful. The administration of recombinant FVIIa could not achieve sustainable amelioration of the outcome of trauma patients in a randomised controlled trial. Raising inhibitors of coagulation (antithrombin) simultaneously to antihaemorragic therapy is being discussed, but seems not reasonable in the acute phase of a life-threatening haemorrage.
