Measuring the effects of Tranexamic Acid during heart surgery

Point-of-care Measurement of the Antifibrinolytic Activity of Tranexamic Acid in Cardiac Surgery

Phase 4 Interventional Insel Gruppe AG, University Hospital Bern · NCT06128330

This study tests different doses of Tranexamic Acid during heart surgery to see if it can help reduce blood loss and the need for blood transfusions.

What this trial studies

This study evaluates the antifibrinolytic activity of Tranexamic Acid (TXA) during cardiac surgery using a new point-of-care diagnostic assay. The trial aims to determine the optimal dosing of TXA to minimize postoperative blood loss and reduce the need for blood transfusions. Patients undergoing elective cardiac procedures such as aortocoronary artery bypass graft surgery or valve replacements will receive varying doses of TXA, allowing for real-time adjustments based on the assay results. The study seeks to establish a standardized approach to TXA administration in the operating room.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 scheduled for elective cardiac surgeries like aortocoronary artery bypass grafting or valve replacements with normal renal function.

Not a fit: Patients with impaired renal function, a history of seizures, or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved blood management and reduced complications for patients undergoing cardiac surgery.

How similar studies have performed: Previous studies have shown positive outcomes with TXA in reducing blood loss during cardiac surgery, supporting the potential success of this approach.
