Lowering driving pressure during surgeries with high risk of postoperative lung complications

Driving Pressure During Surgeries With High Risk for Postoperative Pulmonary Complications

Not applicable Interventional University General Hospital of Patras · NCT07186933

This trial tests whether using the lowest possible driving pressure during mechanical ventilation instead of standard protective settings helps adults having high-risk surgery avoid postoperative lung complications.

What this trial studies

Adults at high risk for postoperative pulmonary complications (ARISCAT score >25) who undergo surgery with general anesthesia and invasive ventilation will receive one of two perioperative ventilation strategies. One group receives conventional lung-protective ventilation and the other undergoes PEEP titration to minimize driving pressure (ΔP). Investigators will compare rates of postoperative pulmonary complications as well as length of hospital stay, ICU admission, and mortality between the groups. All interventions and follow-up are performed at the University Hospital of Patras according to local perioperative care.

Who should consider this trial

Good fit: Adults scheduled for surgery under general anesthesia who will be invasively ventilated and have a preoperative ARISCAT score above 25 are eligible candidates.

Not a fit: Patients who are pregnant, not having general anesthesia with endotracheal intubation, have severe heart failure or severe emphysematous lung disease, or cannot tolerate neuromuscular blockade or cessation of spontaneous ventilation are unlikely to participate or benefit.

Why it matters

Potential benefit: If successful, the lower-driving-pressure approach could reduce postoperative lung complications, shorten hospital stays, and decrease ICU needs and possibly mortality for high-risk surgical patients.

How similar studies have performed: Observational studies and ARDS research associate lower driving pressure with better outcomes, but randomized evidence in high-risk surgical patients is limited.
