Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
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 Results may not be published yet.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.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This trial compares two types of breathing tubes (oral RAE vs. reinforced) used with a video laryngoscope to see which allows faster, safer intubation with fewer throat injuries. Adult patients scheduled for surgery under general anesthesia are randomly assigned to one tube type. The study measures first-attempt success rate, throat soreness, hoarseness, and any airway injury after surgery.

What this could mean

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

Active substance
endotracheal tube (oral RAE or reinforced)
What this could lead to
If one tube type proves better, it could lead to fewer intubation attempts and less throat injury for patients undergoing surgery.
What could go wrong
This is a small, single-center study comparing two tube types; results may not apply to all patients or settings, and the difference between tubes may be small.
