BACKGROUND: The effects of epsilon-aminocaproic acid (EACA) and tranexamic acid (TA) on bleeding and allogeneic transfusions, and the cost of pharmacological and transfusional treatment were compared to aprotinin (AP). METHODS: We randomized 210 patients subjected to elective cardiac surgery. Of these, 68 patients receivedEACA (a bolus of 5 g, an infusion of 2 g/h, and 2.5 g in the priming), 72 patients received TA (a bolus of 1 g, an infusion of 400 mg/h, and 500 mg in the priming), and 70 patients received AP (a bolus of 280 mg, an infusion of 70 mg/h, and 280 mg in the priming). Postoperative blood loss and homologous transfusions were collected and the cost of pharmacological treatment and homologous transfusions were calculated. RESULTS:Bleeding but not allogeneic transfusions was significantly higher in the EACA group (467+/-234 versus TA, 311+/-231 versus AP, 283+/-233; p < 0.001). Costs of pharmacological and transfusional treatment were significantly lower in the TA group ($58.10+/-$105.10) versus the EACA group ($100.70+/-$158.60) versus the AP group ($432.60+/-$118.70) (p < 0.0001). CONCLUSIONS: Compared to AP, TA has the same effects on bleeding and transfusions, but with a significant reduction of costs. Patients treated with EACA showed a significantly higher postoperative bleeding with an increased trend of transfusion requirement.
