Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and over scheduled for elective intra-abdominal surgery with a moderate to high risk of postoperative pulmonary complications.

Probably not a fit

Patients who are expected to have difficult intubation or require postoperative mechanical ventilation may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the feasibility of a multicenter randomized controlled trial comparing two extubation strategies: 'open lung' and 'conventional' in patients undergoing elective intra-abdominal surgery under general anesthesia. It will involve 216 adult patients at moderate or high risk of postoperative pulmonary complications, who will be randomly assigned to one of the two strategies. The study will measure adherence to the extubation protocol and the rates of postoperative pulmonary complications in both groups. The findings will help inform future definitive trials on the effectiveness of these strategies.

Why it matters

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

How similar studies have gone: Previous studies on 'open lung' ventilation have shown mixed results, indicating that this approach is still being explored and may offer novel insights.
