Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Summary

This trial tests four different video laryngoscopes to see which one works best for placing a breathing tube in severely obese patients undergoing weight-loss surgery. About 100 adults will take part, and the study will measure how often the tube is placed successfully on the first try and how long it takes. The goal is to find the most reliable and user-friendly device to improve safety during anesthesia in this high-risk group.

What this could mean

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

Active substance
Four different video laryngoscopes (C-MAC PM, McGrath MAC, VisionPro, AceScope) used for tracheal intubation
What this could lead to
If one device proves clearly better, it could guide safer airway management for severely obese patients, reducing complications during anesthesia.
What could go wrong
The trial is relatively small and results may not apply to all patients or settings. Individual device performance can vary with operator skill, and the study's strict time limits may not reflect real-world conditions.
