Goal-directed vs. Empirical Tranexamic Acid Administrationin Cardiovascular Surgery

Summary

The present study is a multi-center randomized prospective placebo-controlled non-inferiority trial. The study's primary objective is to compare the amounts of postoperative bleeding using two different TXA administration strategies: empirical TXA administration vs. viscoelastic test-based goal-directed TXA administration in cardiovascular surgery. The secondary objectives include comparing the incidents of hyper-fibrinolysis, thromboembolic complications, and postoperative seizures. Researchers assumed that goal-directed tranexamic acid (TXA) administration using viscoelastic field tests would not be inferior to the empirical TXA administration strategy in reducing postoperative bleeding and hyper-fibrinolysis. It also would be beneficial in lowering TXA-induced thromboembolic complications and seizures.
