What this trial studies

This clinical trial investigates the impact of different doses of tranexamic acid and activated clotting time (ACT) levels on bleeding and blood transfusion requirements in adult patients undergoing cardiac surgery. Participants will be divided into four groups based on their tranexamic acid dosage and ACT levels during surgery. The primary outcome measured will be the volume of postoperative bleeding within 24 hours. The study aims to enhance understanding of pharmacological management during cardiac procedures.

Who should consider this trial

Good fit: Ideal candidates are adults scheduled for cardiac surgery requiring cardiopulmonary bypass.

Not a fit: Patients who are pregnant, undergoing emergency procedures, or have severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to reduced bleeding and blood transfusion needs in cardiac surgery patients.

How similar studies have performed: Previous studies have shown promising results with tranexamic acid in reducing bleeding in surgical settings, suggesting potential success for this approach.
