New breathing maneuver may keep lungs open during surgery
NCT ID NCT07349784
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether an automated breathing technique during laparoscopic colorectal cancer surgery can prevent lung collapse (atelectasis). About 56 adults will be randomly assigned to receive either the special breathing maneuvers or standard ventilation. The goal is to see if this technique reduces lung collapse and related complications after surgery.
