Abstract

Reopening sternotomy to control bleeding after coronary artery bypass grafting surgery (CABG) has been reported in 2%-7% of cases. Platelet dysfunction and activation of fibrinolytic cascade are the common causes of bleeding after on-pump CABG. Different antifibrinolytic drugs have been used to reduce bleeding. In this study, we aimed to investigate the efficacy of topical tranexamic acid in reducing postoperative mediastinal bleeding after CABG. Materials and methods: This was a double-blind placebo-controlled randomized clinical trial on 40 patients as the control and another 40 patients as the study group. On completion of CABG before sternotomy wound closure, tranexamic acid (2 g/20 mL) or placebo (20 mL of saline) was diluted in 500 mL of warm saline (37 °C), poured into the pericardial cavity, and left for 5 min. Results: There was no significant difference in baseline demographic data and laboratory results between the 2 groups (P > 0.05). Mediastinal bleeding and packed red cell transfusion requirements were significantly lower in the study group (P =< 0.01). There were no complications related to topical tranexamic such as mortality, myocardial infarction, cerebrovascular accident, seizure, or renal failure. Conclusion: Topical tranexamic acid can reduce mediastinal bleeding and packed red cell transfusion requirements after CABG.
