Multicenter Study Comparative Study3-Factor Versus 4-Factor Prothrombin Complex Concentrate for Warfarin Reversal in Severe Bleeding: A Multicenter, Retrospective, Propensity-Matched Pilot Study.
Current guidelines recommend 4-factor prothrombin complex concentrate (4PCC) for emergent reversal of bleeding secondary to warfarin. While current research has demonstrated superiority of 4PCC over plasma, direct comparisons with 3-factor PCC (3PCC) are lacking. The purpose of this study is to compare the efficacy and safety of 3PCC and 4PCC. ⋯ A total of three thrombotic events were documented, all in the 4PCC group. We found no difference in the rate of INR reversal in those treated with 3PCC and 4PCC. However, those with a baseline INR > 4.0 may experience more successful INR reversal with 4PCC.
