What the study statuses mean

This study's is highlighted.

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.
By invitation only This study
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 Results may not be published yet.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.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study compares two methods of removing a breathing tube after surgery under general anesthesia: deflating the cuff first (standard) or keeping it inflated. Researchers want to see which method better prevents fluids from entering the windpipe and lungs. About 88 healthy adults having non-airway surgery will take part, and a chest X-ray will check for any fluid leakage.

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 it works, this could point toward a safer standard method for removing breathing tubes during anesthesia.
What could go wrong
This is a small, early-stage study in healthy adults, so results may not apply to sicker patients or emergency surgeries. The outcome is based on a dye test, not direct patient harm.
