Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adult patients aged 18 and older scheduled for coronary artery bypass surgery or valve replacement/repair with a EuroSCORE II of 2 or higher.

Probably not a fit

Patients undergoing emergency surgeries, off-pump cardiac surgeries, or those participating in other interventional trials may not benefit from this study.

What this trial studies

This study aims to evaluate the feasibility of conducting a multicenter randomized controlled trial comparing hypothermic and normothermic cardiopulmonary bypass (CPB) during adult cardiac surgeries. It will assess recruitment and delivery methods in the UK, utilizing a novel remote data capture system for data collection. The study seeks to gather pilot data to inform a larger trial that will determine the optimal temperature management during CPB for improved patient outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved safety and outcomes for patients undergoing heart surgery by identifying the best temperature management strategy during CPB.

How similar studies have gone: Previous studies have shown mixed results regarding temperature management during CPB, making this approach both relevant and necessary for further investigation.
