| Popis: | Background . In this study we compared the clinical efficiency, safety, and economic benefit of low-dose aprotinin with epsilon aminocaproic acid (EACA) in reducing bleeding after cardiopulmonary bypass operation. Methods . In a double-blind, randomized study, 100 patients received low-dose aprotinin (2 × 10 6 kallikrein inhibitor units) or EACA (20 g). The surgical procedure was single- or double-valve replacement with or without coronary artery bypass grafts. Results . Mediastinal chest drainage and transfusion requirements with both therapies were similar. There were no urgent reoperations to secure hemostasis in either group. Similar levels of D-dimer with both therapies indicate a similar inhibition of fibrinolysis. Release of troponin I was less in the low-dose aprotinin group 1 and 4 hours after bypass, although electrocardiographic measurements did not reflect this difference. Levels of S-100β and neuron-specific enolase were similar with both therapies, confirming that there was no difference in the occurrence of any adverse neurologic events in either group. Conclusions . Low-dose aprotinin and EACA showed similar effects on the reduction of intraoperative and postoperative bleeding. The lower cost of EACA with no change in safety outcome suggests it is the preferred treatment. |
