There are increasing reports comparing the safety and efficacy of both 3F- and 4F-PCCs that deserve particular attention. Cochrane Database Syst Rev. Reversal of warfarin associated coagulopathy with 4-factor prothrombin complex concentrate in traumatic brain injury and intracranial hemorrhage. Suboptimal effect of a three-factor prothrombin complex concentrate Profilnine-SD in correcting supratherapeutic international normalized ratio due to warfarin overdose. In addition, existing consumptive coagulopathy may lead to decreased procoagulant constituents. Intrinsic Xase generates factor Xa by times more than extrinsic Xase. Pharmacology and management of the vitamin K antagonists:

Small, retrospective studies have described using PCCs to correct warfarin-related hemorrhage after CPB 77 by using the same INR, weight-based dosing algorithm previously described by Sarode et al. Initial administration of rFVIIa may therefore appear clinically inadequate for hemostasis, lead to repeated administration and eventual overcorrection of thrombin generation by indirectly increasing prothrombinase levels Figure 1. However, once Factor II concentrations are subsequently restored i. Recommendations for the management of intracranial haemorrhage – part I: Factor Xa inhibitors directly reduce Factor Xa activity and indirectly reduce thrombin generation downstream.

These include hemophiliacs, 26 other congenital factor deficiencies, 27 cardiac surgery patients experiencing perioperative hemorrhage, 28 — 30 and the general population of patients for venous thromboembolic disease.

The loss of intrinsic Xase activity in hemophiliacs due to the presence of inhibitor alloantibodies minimizes Factor Xa production, depriving the prothrombinase complex of its thrombin generation capacity. 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.

Observational studies evaluating the use of PCCs in the treatment of coagulopathy related to the direct Factor Xa inhibitors suggest these compounds are able to sudy the anticoagulant effects by increasing the production of prothrombinase, thereby leading to thrombin generation Figure 3.

Interact Cardiovasc Thorac Surg. 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. This strategy may be especially helpful in order to account for the different concentrations of factor levels among various PCC formulations Table 1.

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.

Clinical experience with oral versus intravenous vitamin K for warfarin reversal. Support Center Support Center. This assertion is supported by Karkouti, et al. Vitamin K antagonists also act to reduce the synthesis of coagulants downstream from the Vitamin K-dependent coagulation factors, therefore weakening the resultant fibrin cross-linkage. The promise of the ability to clinically determine thrombin generation during the perioperative period may provide a potential ztudy for targeted PCC administration while avoiding thromboembolic events.

Additionally, a net-like fibrinogen deposition was noted in the lung capillaries of the higher dosage group, which was present but not as sudy developed in the control and low-dosage animals.
