What this trial studies

This study evaluates the efficacy and side effects of re-infusing unwashed shed blood during off-pump coronary artery bypass surgery using a novel cardiotomy circuit. It aims to compare clinical outcomes, transfusion requirements, inflammatory responses, and cognitive status between patients receiving this intervention and those undergoing conventional techniques. The study will involve randomizing participants into two groups, with one group receiving the experimental treatment and the other following standard care. The research is set to take place at Damascus University Cardiac Surgery Hospital over a two-year period.

Who should consider this trial

Good fit: Ideal candidates are patients aged 40 to 75 undergoing isolated off-pump coronary artery bypass surgery.

Not a fit: Patients with impaired left ventricular function, renal or hepatic failure, or those requiring emergency operations may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could reduce the need for blood transfusions and associated complications during cardiac surgery.

How similar studies have performed: While the use of auto-transfusion techniques has been explored, this specific approach using an isolated cardiotomy circuit is relatively novel and has limited prior data.
