Comparing airway management techniques for single-lung ventilation in heart surgery

Comparison of Postoperative Pulmonary Complications in Patients Undergoing Minimal Invasive Cardiac Surgeries With the Use of Bronchial Blocker and Double-Lumen Tube in Airway Management

Not applicable Interventional Ankara City Hospital Bilkent · NCT06299735

This study is testing whether using a double-lumen tube or a bronchial blocker is better for helping patients breathe during heart surgery that only requires one lung to be used.

What this trial studies

This clinical trial aims to compare the effectiveness of a double-lumen tube versus a bronchial blocker for single-lung ventilation in patients undergoing minimally invasive cardiac surgeries. It is a single-center, prospective, randomized study involving 66 patients who will be randomly assigned to one of the two airway management techniques. The study will evaluate postoperative pulmonary functions, duration of application, success in lung collapse, and the number of repositioning attempts for both methods. Standard anesthesia protocols will be followed for all participants.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and above scheduled for on-pump minimally invasive cardiac surgeries requiring single-lung ventilation.

Not a fit: Patients with advanced organ failure, severe lung diseases, or those undergoing emergency surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve postoperative pulmonary outcomes for patients undergoing minimally invasive cardiac surgery.

How similar studies have performed: Previous studies have shown varying success with similar airway management techniques, but this specific comparison is novel.
