BACKGROUND:Fresh frozen plasma (FFP) and prothrombin complex concentrates (PCC) reverse oral anticoagulants. We compared PCC and FFP intraoperative administration in patients undergoing heart surgery with cardiopulmonary bypass (CPB). METHODS:Forty patients [with international normalized ratio (INR)≥ 2·1] assigned semi-urgent cardiac surgery were randomized to receive either FFP (n = 20) or PCC (n = 20). Prior to CPB, they received either 2 units of FFP or half of the PCC dose calculated according to body weight, initial INR and target INR ( ≤ 1·5). After CPB and protamine administration, patients received either another 2 units of FFP or the other half PCC dose. Additional doses were administered if INR was still too high ( ≥ 1·5). RESULTS: Fifteen minutes after CPB, more patients reached INR target with PCC (P = 0·007): 7/16 patients vs. 0/15 patients with FFP; there was no difference 1 h after CPB (6/15 patients with PCC vs. 4/15 patients with FFP reached target). Fifteen minutes after CPB, median INR (range) decreased to 1·6 (1·2-2·2) with PCC vs. 2·3 (1·5-3·5) with FFP; 1 h after CPB both groups reached similar values [1·6 (1·3-2·2) with PCC and 1·7 (1·3-2·7) with FFP]. With PCC, less patients needed additional dose (6/20) than with FFP (20/20) (P < 0·001). Both groups differed significantly on the course of factor II (P = 0·0023) and factor X (P = 0·008) over time. Dilution of coagulation factors was maximal at CPB onset. Safety was good for both groups, with only two related oozing cases with FFP. CONCLUSION:PCC reverses anticoagulation safely, faster and with less bleeding than FFP.
