Comparing two ventilation methods for obese patients during bariatric surgery

Driving Pressure Guided Ventilation Versus Conventional Lung Protective Strategy in Morbid Obese Patients Undergoing Laparoscopic Bariatric Surgery; a Prospective Randomized Controlled Study

Not applicable Interventional Tanta University · NCT04861168

This study is testing if a new way of helping obese patients breathe during bariatric surgery works better than the usual method to see if it helps them recover more safely.

What this trial studies

This study evaluates the effectiveness of driving pressure guided ventilation versus conventional lung protective ventilation in morbidly obese patients undergoing laparoscopic bariatric surgery. The primary focus is on intraoperative oxygenation levels, while secondary outcomes include the incidence of postoperative pulmonary complications such as hypoxia and respiratory failure. By comparing these two ventilation strategies, the study aims to determine which method better minimizes lung injury and improves postoperative recovery in this high-risk population.

Who should consider this trial

Good fit: Ideal candidates are morbidly obese patients with a BMI between 40-50 kg/m2, aged 18-60, and classified as ASA physical status III, scheduled for laparoscopic bariatric surgery.

Not a fit: Patients with severe respiratory diseases, recent major pulmonary surgeries, or contraindications to PEEP will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved respiratory outcomes and reduced complications for morbidly obese patients undergoing surgery.

How similar studies have performed: Previous studies have suggested the potential benefits of driving pressure guided ventilation in similar patient populations, indicating that this approach may be promising.
