Bleeding, Transfusions and Medical Management
Data presented in Table 2 reveal that patients in the ATAAD group received significantly more transfusions and procoagulants during surgery and the first 24 hours after surgery. Transfusion of packed red blood cells (3.3U (±4.0) vs 1.2U (±1.5), p= 0.03), platelets (4.3U (±1.7) vs 2.5U (±1.6), p= 0.001) and FFP (2.4U (±2.6) vs 0.6U (±1.2), p< 0.01) was larger in the ATAAD group. The use of fibrinogen (6.0g (±3.4) vs 3.1g (±2.5), p< 0.01), PCC (1780IU (±1050) vs 775IU (±896), p< 0.01) and recombinant factor VIIa (5 (22%) vs 0 (0%) patients, p= 0.03) also were significantly larger in the ATAAD group. No patient was reoperated for bleeding in both groups and postoperative bleeding volumes at 12h (492ml (±235) vs 498ml (±175), p= 0.64) and 24h (810ml (±400) vs 740ml (±215), p= 0.78) did not show any difference between groups.
