Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This study compared two ways to manage a patient's airway during laparoscopic gallbladder surgery: a video laryngeal mask and an endotracheal tube. Researchers measured how long each took to insert and checked breathing and pressure readings. The goal was to see if the video mask could be a good alternative to the standard tube.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could show that a video laryngeal mask is a safe and effective alternative to an endotracheal tube for certain surgeries, potentially reducing complications.
What could go wrong
This is a small, completed study with 102 participants. Results may not apply to all patients or surgeries, and the video laryngeal mask may not be suitable for those with higher aspiration risk.
