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).


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).


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.


PCC reverses anticoagulation safely, faster and with less bleeding than FFP.
