Can a breathing mask after surgery save lungs? new trial investigates
NCT ID NCT03629431
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether giving patients non-invasive ventilation (a mask that helps them breathe) soon after surgery could prevent serious lung complications. It included 266 adults at high risk (based on a score called ARISCAT) who were having surgery under general or regional anesthesia. Half received the breathing support in the ICU for at least 24 hours, while the other half got standard post-surgery care. The goal was to see if the mask treatment reduced the need for a breathing tube or ventilator within the first week.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- non-invasive ventilation (breathing support via mask)
- What this could lead to
- If it works, this could lead to a standard preventive breathing treatment for patients at high risk of lung problems after surgery.
- What could go wrong
- This trial is completed but results are not yet widely adopted. The benefit may be small or limited to certain patients, and the treatment requires intensive care monitoring.
