Comparing Bronchial Blockers and Double-Lumen Tubes for One-Lung Ventilation in Obese Adults Undergoing Lung Surgery

What this Trial Is About

Researchers are evaluating the effectiveness of two devices, bronchial blockers and double-lumen tubes, in achieving one-lung ventilation during lung resection surgery in obese patients. The main focus is to determine if there is a significant difference in intraoperative hypoxia between the two devices. This trial aims to compare their performance and safety in this specific patient group. Participants will be randomly assigned to one of two groups one group will receive one-lung ventilation using a bronchial blocker, while the other group will use a double-lumen tube. Both devices are used during lung resection surgeries such as lobectomy, segmentectomy, or wedge resection performed by either VATS or thoracotomy. The study involves single masking and no placebo control. During the surgery, researchers will monitor several measures including lung collapse, surgical visualization, insertion time, repositioning, and any device changes. They will also track oxygen levels, ventilation parameters, pressures, blood gases, and complications both during and immediately after surgery. No additional tasks are required from participants. The study starts from anesthetic induction through one-lung ventilation and continues with follow-up during the first 24 hours post-surgery.
