What this trial studies

This study aims to compare two different ventilation strategies in obese patients undergoing laparoscopic bariatric surgery: individualized PEEP ventilation guided by driving pressure and a conventional lung protective strategy. The effectiveness of these methods will be assessed using lung ultrasound scores to evaluate lung function and safety. The study will include patients with a BMI between 30-40 kg/m2 and ASA physical status II or III, aged 18 to 60 years. The goal is to determine which ventilation approach provides better outcomes for this specific patient population.

Why it matters

Potential benefit: If successful, this study could lead to improved respiratory outcomes and safety during bariatric surgery for obese patients.

How similar studies have gone: Other studies have shown promising results with individualized ventilation strategies, suggesting potential benefits in similar patient populations.
