Summary

This study tested two methods of removing a breathing tube after digestive surgery to see which one helps patients breathe better. 208 adults having surgery lasting over an hour took part. One group had the tube removed the usual way, and the other had it removed while still connected to the breathing machine. The main goal was to see which method led to fewer drops in oxygen levels.
