title: Intraoperative use of recombinant activated factor VII (rFVIIa).
abstract: Recombinant activated factor VII (rFVIIa, Novoseven, Novo Nordisk, Denmark) was introduced as a prohemostatic agent in the early 80s: the only indication approved in USA by Food and Drug Administration (FDA) is the spontaneous bleeding in congenital hemophilia patients who developed inhibitors to FVIII and FIX. Recently, EMEA approved the use of rFVIIa in congenital hemophilia patients with inhibitors undergoing surgery, in subjects with congenital FVII deficiency undergoing surgical or invasive procedures, in patients with acquired hemophilia and in case of Glanzmann's thromboasthenia. Out of these approved indications, the off label use of rFVIIa is rapidly expanding, particularly in surgical patients with acquired coagulation disorders in order to manage severe, uncontrolled bleeding nonresponsive to conventional therapeutic measures or to reduce blood loss and transfusion requirements in potentially bleeding surgical procedures (major liver surgery, liver transplantation, major abdominal or obstetric surgery, trauma surgery). This paper reviews the more recent data coming from retrospective or prospective studies performed in different surgical settings: so far, the major point to be addressed is the place for rFVIIa as an adjunctive but sometimes lifesaving treatment to control haemostasis and critical bleeding in surgery and critically ill patients.
