Driving pressure-guided individualized PEEP vs standard PEEP during upper abdominal surgery

Official title: Driving Pressure-Guided Individualized PEEP Versus Standard PEEP: Effects on Postoperative Pulmonary Complications in Upper Abdominal Digestive Surgery

Run by Hopital Charles Nicolle · NCT07885124 · Data updated 2026-11-12

In this randomized trial, adults at higher risk of breathing problems after upper abdominal surgery will try a personalized PEEP level based on the lowest driving pressure and compare it to a fixed PEEP of 5 cmH2O to see if it lowers postoperative lung complications.

Is this trial a fit for you?

Likely a good fit

Adults 18+ scheduled for upper abdominal digestive surgery with moderate-to-high risk of pulmonary complications (ARISCAT score ≥26).

Probably not a fit

Patients with contraindications to lung recruitment maneuvers or very stable or very low risk of pulmonary complications may not benefit.

What this trial studies

This prospective, randomized trial compares two strategies for setting PEEP during general anesthesia in adults undergoing supra-mesocolic upper abdominal digestive surgery. All participants receive lung-protective ventilation; one group has PEEP tailored to achieve the lowest driving pressure after a lung recruitment maneuver, while the other group maintains PEEP at 5 cmH2O. The primary endpoint is the occurrence of one or more postoperative pulmonary complications within the first 7 days after surgery. Outcomes are assessed by an independent postoperative assessor, with care standardized across groups.

Why it matters

Potential benefit: If successful, individualized PEEP could reduce postoperative lung complications and shorten hospital stay.

How similar studies have gone: Previous research suggests driving-pressure guided PEEP may improve respiratory mechanics, but findings vary by setting and population.
