Cardiopulmonary Bypass Clinical Trial
Official title:
The Dose Effect of Activated Clotting Time and Tranexamic Acid on Bleeding in Adult Cardiac Surgery
The goal of this clinical trial is to the dose effect of tranexamic acid and the level of ACT on bleeding in adult cardiac surgery. The main questions it aims to answer are: 1. Does higher dose of tranexamic acid reduce the amount of bleeding and blood transfusion? 2. Does lower ACT level during cardiac surgery reduce the amount of bleeding and blood transfusion? Participants will divided into four groups which have different tranexamic acid dose and ACT level during cardiac surgery to see if there is any different in the amount of bleeding and blood transfusion.
This study is going to analyze the medical records of patients who underwent cardiac surgery between December 1, 2023, and December 31, 2026. The investigators will categorize patients into four groups based on anticoagulation indices (ACT 400-600 seconds; ACT > 600 seconds) and tranexamic acid dosages (low dose; high dose) within the range considered safe for CPB. The primary outcome will be the volume of postoperative bleeding within 24 hours for each group. The findings of this study will contribute to the existing clinical evidence and provide insights for the monitoring and pharmacological management in cardiac surgery. ;
