What this trial studies

This clinical trial aims to evaluate the effectiveness of preoperative tranexamic acid (TXA) in reducing bleeding during and after major colorectal surgery. It is a prospective, pragmatic, randomized trial comparing patients receiving TXA to those who do not. The study will measure changes in hemoglobin levels and the incidence of bleeding complications within 30 days post-surgery, while also assessing any potential increase in thromboembolic events. Participants will receive TXA intravenously at the start and end of their surgical procedure.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are scheduled for elective or non-elective inpatient abdominal and pelvic colorectal surgery.

Not a fit: Patients with severe renal impairment, a history of thromboembolic disease, or those who are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of bleeding complications in patients undergoing major colorectal surgery.

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