A single center randomized controlled trial (RCT) was conducted at Harapan Kita National Cardiovascular Center, Jakarta, Indonesia as the tertiary cardiovascular referral hospital. The RCT was conducted from October 1 th, 2022 until January 6 th, 2023 (current status: completed). This study aims to determine whether topical tranexamic acid is more effective on the amount of bleeding and the need for postoperative blood product transfusion compared with placebo in patients undergoing cardiac surgery and specifically measure the difference outcome between coronary artery bypass graft (CABG), off pump coronary bypass graft cardiac surgery (OPCAB), and adult heart valve surgery. The control group in this study is given 100 mL of normal saline. The subjects were adults undergoing elective cardiac surgery (CABG, OPCAB, and heart valve surgery). Both the patients and the principal investigators were blinded for the treatment-control allocation. The patients were purposively selected and were randomly assigned to one of the arms with block randomization. The primary outcomes of this study comprised of two parameters; post operative bleeding and blood product transfusion. The primary outcomes were assessed during the operation, until 48-hour post operative.
This is a single-center, double-blind, randomized controlled trial (RCT) comparing two groups of application of topical dose of tranexamic acid (TxA) versus placebo in patients undergoing coronary artery bypass graft (CABG), off pump coronary bypass graft cardiac surgery (OPCAB), and adult heart valve surgery. The primary outcomes of this study comprised of two parameters; post operative bleeding and blood product transfusion. The primary outcomes were assessed during the operation, until 48-hour post operative.
