Comparative Study Observational StudyComparative effectiveness of 3- versus 4-factor prothrombin complex concentrate for emergent warfarin reversal.
Three- and 4-factor prothrombin complex concentrates (PCC) are routinely administered for emergent reversal of warfarin, but direct comparisons of clinical outcomes are lacking. The purpose of this study was to compare the safety and effectiveness of 3- and 4-PCC in patients requiring emergent warfarin reversal. ⋯ Patients who received 4-PCC, and those with INR≤1.5 regardless of type of PCC received were more likely to survive. Thromboembolic events were low in both groups and similar to previous studies.

Less Is More: Low-dose Prothrombin Complex Concentrate Effective in Acute Care Surgery Patients.
Optimal dosing of prothrombin complex concentrate (PCC) has yet to be defined and varies widely due to concerns of efficacy and thrombosis. We hypothesized a dose of 15 IU/kg actual body weight of a three-factor PCC would effectively correct coagulopathy in acute care surgery patients. Retrospective review of 41 acute care surgery patients who received 15 IU/kg (± 10%) actual body weight PCC for correction of coagulopathy. ⋯ No statistical differences were seen between trauma and nontrauma patients. One thrombotic event occurred. Administration of low-dose PCC, 15 IU/kg actual body weight, effectively corrects coagulopathy in acute care surgery patients regardless of warfarin use, diagnosis or plasma transfusion.

Multicenter StudyManagement of new oral anticoagulants related life threatening or major bleedings in real life: a brief report.
Although new oral anticoagulants (NOAs) have been marketed in many countries, concern exists about the management of bleedings related to these drugs due to the lack of specific antidotes. The aim of our study was to report on real life management of NOAs-related life-threatening or major bleedings. We report data from consecutive cases of NOAs related major bleedings admitted to 4 hospitals since NOAs became marketed in Italy. ⋯ All patients were discharged alive and NOAs were discontinued. In NOAs related major gastro-intestinal bleeding general supportive measures seem to be effective for the majority of patients. Despite promoting bleeding cessation, 4-factor PCC does not reverse abnormal coagulation parameters.

An 80-year-old woman had the anticoagulant effect of dabigatran etexilate reversed using factor eight inhibitor bypassing activity (FEIBA) in order to facilitate emergency surgery for an incarcerated femoral hernia. She had atrial fibrillation was taking the anticoagulant for stroke prevention. That afternoon her international normalised ratio (INR) was 1.3 and activated partial thromboplastin time ratio (APPTr) was 2.17, having taken dabigatran that morning. 3000 units of FEIBA and 10 mg of vitamin K were administered and she was taken to theatre for emergency surgery. ⋯ She made an uneventful postoperative recovery and was discharged home. There is a limited evidence base guiding practice in the clinical scenario described. The only controlled studies available are animal experiments.
