Personalized breathing support during laparoscopic weight loss surgery

Effects of Individualized Positive End-Expiratory Pressure (PEEP) on Oxygenation, Hemodynamic Variables, and Incidence of Early Postoperative Atelectasis in Patients Undergoing Laparoscopic Bariatric Surgery: A Prospective Randomized Controlled Study

Not applicable Interventional Tanta University · NCT06115668

This study is testing whether adjusting breathing support for each patient during weight loss surgery can help improve their lung function and reduce complications after the operation.

What this trial studies

This study evaluates the effectiveness of individualized positive end-expiratory pressure (PEEPIND) titration compared to a fixed PEEP of 5 cmH2O in obese patients undergoing laparoscopic bariatric surgery. The focus is on improving oxygenation, hemodynamic stability, and reducing early postoperative complications such as atelectasis. By tailoring PEEP to each patient's needs, the study aims to enhance lung function and minimize respiratory issues during and after surgery. The trial will involve monitoring various respiratory and hemodynamic parameters throughout the procedure.

Who should consider this trial

Good fit: Ideal candidates are obese patients aged 21 to 60 scheduled for elective laparoscopic bariatric surgery with ASA physical status class I-III.

Not a fit: Patients with chronic respiratory conditions, heart failure, or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative complications and improve recovery outcomes for obese patients undergoing bariatric surgery.

How similar studies have performed: While the use of PEEP in surgical settings is established, the individualized approach in this specific context is novel and has not been extensively tested.
