Résumé
<p><b>OBJECTIVE</b>To evaluate the efficacy of antifibrinolytic agents in coronary artery bypass grafting (CABG) patients receiving antiplatelet.</p><p><b>METHODS</b>We searched PubMed, EMbase, Highwire, CENTREN and its affiliated clinical trial registration data center, CBMdisc and CNKI databases from 2000 to 2010. Randomized controlled trials investigating the efficacy of anti-fibrinolytic agents (aprotinin and tranexamic acid) in CABG patients were identified. Study selection and meta-analysis were conducted according to the Cochrane Handbook for systematic reviews. Date were extracted from these trials by 2 reviewers independently and analyzed by RevMan 5.0 software.</p><p><b>RESULT</b>Eleven RCT trials (n = 725) were included and data confirmed the efficacy of antifibrinolytic therapy in terms of reducing bleeding within 24 hours after operation (MD = -306.5 ml, 95%CI: -351.52 to -261.52, P < 0.01), number of patients who need blood transfusion (OR = 0.37, 95%CI: 0.26 to 0.51, P < 0.01), amount of blood transfusion (MD = -0.59 U, 95%CI: -0.69 to -0.50, P < 0.01), surgical re-exploration(OR = 0.27, 95%CI: 0.09 to 0.78, P = 0.02), and thrombotic events (OR = 0.49, 95%CI: 0.25 to 0.97, P = 0.04) in CABG patients receiving antiplatelet, while compared with blank treatment.</p><p><b>CONCLUSION</b>This analysis showed that antifibrinolytic agents are effective for reducing bleeding within 24 hours after operation, amount of blood transfusion, surgical re-exploration and do not increase the incidence of thrombotic events in CABG patients receiving antiplatelet before operation.</p>
