While the potential for unopposed thrombin generation remains a concern with the administration of 4F- or 3F-PCCs, FFP contains both coagulation factors and naturally occurring anticoagulants. Antithrombin deficiency increases thrombin activity after prolonged cardiopulmonary bypass. Efficacy of red blood cell transfusion in the critically ill: Effects of prothrombin complex concentrate and recombinant activated factor VII on vitamin K antagonist induced anticoagulation. A specific antidote for dabigatran: Prothrombin complex concentrates–evaluation of safety and thrombogenicity. Reversal of drug-induced anticoagulation:

The promise of the ability to clinically determine thrombin generation during the perioperative period may provide a potential guide for targeted PCC administration while avoiding thromboembolic events. Safety and efficacy of prothrombin complex concentrates for the treatment of coagulopathy after cardiac surgery. Assessment of thrombin generation measured before and after cardiopulmonary bypass surgery and its association with postoperative bleeding. Thromboelastometrically guided transfusion protocol during aortic surgery with circulatory arrest: Evaluation of dynamic parameters of thrombus formation measured on whole blood using rotational thromboelastometry in children undergoing cardiac surgery:

Prediction of venous thromboembolism in patients with cancer by measuring thrombin generation: The ability of PCCs to support the enzyme complexes that convert Factor II to IIa illustrates their efficacy as hemostatic agents as well as potentially contributing to prothrombotic risk.

Correction of hypofibrinogenemia and thrombocytopenia prior to the administration of PCCs may be prudent in order to maximize the efficacy of lower PCC dosing and minimize the risk for adverse thromboembolic events. Recommendations for the management of intracranial haemorrhage – part I: General Surgery, Hepatic Injury, and Liver Transplantation Literature related to the administration of PCCs during noncardiac surgery for perioperative bleeding is mainly related to vitamin K antagonist reversal or supplementation of factors in the setting of liver failure.

Comparison of three-factor and four-factor prothrombin complex concentrates regarding reversal of the anticoagulant effects of rivaroxaban in healthy volunteers. Blood transfusion, independent of shock severity, is associated with worse outcome in trauma.

Augmentation of thrombin generation in neonates undergoing cardiopulmonary bypass. Efficacy and safety of a 4-factor prothrombin complex concentrate in patients on vitamin K antagonists presenting with major bleeding: In this review, we examined the mechanism of action of PCCs and the importance of its individual factor components in promoting hemostasis and thrombosis.

With that said, rFVIIa as a general hemostatic agent remains unproven, in addition to concerns about thromboembolism.

Vitamin K-dependent anticoagulants protein C and S are not illustrated. Off-label use of recombinant activated factor VII in intractable haemorrhage after cardiovascular surgery: Thromboembolic adverse events after use of recombinant human coagulation factor VIIa.

The pivotal trial in the FDA approval of 4F-PCCs was a prospectively randomized, plasma-controlled, study involving patients enrolled at 36 centers demonstrating that 4F-PCCs were an effective alternative to FFP for the urgent reversal of vitamin K antagonist therapy. A specific antidote for dabigatran: Increased volume of distribution for recombinant activated factor VII and longer plasma-derived factor VII half-life may explain their long lasting prophylactic effect.

Guidelines for the management of spontaneous intracerebral hemorrhage: Thrombin generation is impaired during CPB in a manner similar to that of consumptive coagulopathy.

Prothrombin Complex Concentrates for Bleeding in the Perioperative Setting

Platelets and thrombin generation. Rapid reversal of oral anticoagulation with warfarin by a prothrombin complex concentrate Beriplex: The process of coagulation includes clot formation, propagation, stabilization, and clot dissolution.

  KUMULATIVE DISSERTATION TU DRESDEN

Initial administration of rFVIIa may therefore appear clinically inadequate for hemostasis, lead to repeated administration and eventual overcorrection of thrombin generation by indirectly ztudy prothrombinase levels Figure 1.

Inflammatory response to cardiopulmonary bypass. Kamrouz Ghadimi, MD Attestation: A study of perioperative bleeding risk and treatment outcomes in 60 patients.

These two reactions occur independent of one another in the presence of thrombin. Safety of recombinant activated factor VII in randomized clinical trials.

Antidotes progress for new oral clotbusters. In a cell-based model of coagulation, most factors display a threshold relationship with thrombin generation such that marked coagulation factor deficiency is required before thrombin generation is adversely affected. A multicenter, randomized, caee clinical trial of transfusion requirements in critical care.

Prothrombin Complex Concentrates for Bleeding in the Perioperative Setting

Comparison of fresh frozen plasma and prothrombin complex concentrate for the reversal of oral anticoagulants in patients undergoing cardiopulmonary bypass surgery: Cochrane Database Syst Rev. British Committee for Standards in Haematology Prothrombotic risk is increased with repeat or excessive dosing due to promotion of thrombin generation and therefore fibrin cross-linkage Stury 1.
