In vitro evaluation of prothrombin complex concentrates in a thrombin generation assay, using DAPA and purified components of the prothrombinase complex, demonstrated significant levels of coagulant-active "phospholipid replacing" activity. Quantification of this activity showed a significant correlation (r = 0.8747, p less than 0.01) with thrombogenicity measured in vivo in a stasis model in r...

Background Incidence and mortality from traumatic intra-cranial haemorrhage (ICH) is increased in patients on warfarin [1]. Prothrombin Complex Concentrates (PCC) rapidly reverse warfarin anti-coagulation and have been shown to reduce haematoma expansion and mortality in warfarinised patients sustaining ICH [2]. We aimed to determine the feasibility of pre-hospital use of PCCs by physicians and...

Prothrombin (factor II) deficiency is a rare autosomal recessive coagulation disorder that occurs in approximately 1 in 1-2 million people. Prothrombin is activated to thrombin, which in turn proteolytically cleaves fibrinogen to fibrin and contributes to forming a stable fibrin clot. The haemostatic level of prothrombin is thought to be between 20 and 40%, and the half-life is approximately 3 ...

This report describes the management of a bleedinq episode following exodontia in a patient with severe hemophilia A and inhibitor to Factor VIII. For this patient activated prothrombin complex concentrates provided an effective method of controlling hemorrhage. Maintaining hemostasis in the surgical patient who has hemophilia A and inhibitor to Factor VIII is a difficult challenge for dentists...

The course and treatment of a life-threatening hemorrhagic episode in a patient with hemophilia A whose plasma contained a high concentration of an inhibitor of factor VIII activity is presented. The inhibitor of factor VIII was localized to the most anodal fractions of immunoglobulin G on electrophoresis, and was thus presumed to be an antibody directed against factor VIII. No therapeutic bene...

Critical care physicians are increasingly facing patients receiving oral anticoagulation for either cessation of major haemorrhage or to reverse the effects of vitamin K antagonists ahead of emergency surgery. Rapid reversal of anticoagulation is particularly essential in cases of life-threatening bleeding. In these situations, guidelines recommend the concomitant administration of prothrombin ...

Dabigatran is effective in decreasing the risk of ischaemic stroke in patients with atrial fibrillation. However, like all anticoagulants, it is associated with a risk of bleeding. In cases of trauma or emergency surgery, emergency reversal of dabigatran-induced anticoagulation may be required. A specific reversal agent for dabigatran, idarucizumab, has been approved by the US Food and Drug Adm...
