Topical Application of Tranexamic Acid to Reduce Post-operative Bleeding in Coronary Artery Bypass Surgery

Summary

The goal of this project is to determine whether the use of tranexamic acid, a clot-promoting drug, applied topically over the heart in coronary artery bypass graft surgery (CABG) will reduce post operative blood loss. The investigators' hypothesis is that the use of a tranexamic acid-containing cardiac bath prior to chest closure will result in a statistically significant reduction in blood loss and transfusion requirements in patients who undergo CABG.
