Prothrombin Complex Concentrates for Bleeding in the Perioperative Setting.
Prothrombin complex concentrates (PCCs) contain vitamin K-dependent clotting factors (II, VII, IX, and X) and are marketed as 3 or 4 factor-PCC formulations depending on the concentrations of factor VII. PCCs rapidly restore deficient coagulation factor concentrations to achieve hemostasis, but like with all procoagulants, the effect is balanced against thromboembolic risk. The latter is depend...

923 April 2015 P rothrombin complex concentrates (PCCs) are recommended in preference to other treatments such as therapeutic plasma for urgent reversal of vitamin K antagonists.1,2 PCCs contain either three or four coagulation factors (factors ii, iX, and X, with or without factor Vii) and, depending on formulation, low doses of coagulation inhibitors such as protein C, protein S, and heparin ...
متن کاملProthrombin complex concentrates in warfarin anticoagulation reversal
Anticoagulation is very effective for primary and secondary prevention of thromboembolic events. However, questions persist about the risks and management of over-anticoagulation. The annual incidence of major bleeding in trials and cohort studies has been reported to be between 1.1% and 2.3% in patients treated with warfarin to achieve an international normalized ratio (INR) of 2.0 to 3.0. The...
متن کاملProthrombin Complex Concentrates Use in Intracerebral Hemorrhage.
We would treat with 4-factor PCCs because otherwise—with an INR of 1.9—there is a high risk of further expansion of an already large ICH. Without reversal of the anticoagulant effects of warfarin, the patient’s life is at stake. At age 65 years, he has a reasonable chance to recover from a right-sided ICH if treated early and aggressively. In our eyes, early withdrawal of care is not an option!...
متن کاملThrombogenic properties of prothrombin complex concentrates.
In a recent paper White et al.’ reported that the thrombogenic properties of prothrombin complex concentrates (PCC) are due to the presence of factors IXa and Xa. The presence of these activated factors, however, was detected indirectly by applying different inhibitors, e.g., a specific seryl reagent, phenylmethylsulfonyl fluoride (PMSF). They concluded that the effect of PMSF is due to the ina...
