New study aims to predict breathing tube removal success

NCT ID NCT07577453

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 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 Results may not be published yet.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.
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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study watches 150 adults having planned surgery to see if combining three monitoring checks—breathing pattern, muscle strength, and brain activity—can better predict when it's safe to remove the breathing tube. Doctors will record these checks before removing the tube and watch for any breathing problems for 30 minutes after. The goal is to find a more accurate way to avoid complications after anesthesia.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients undergoing elective surgery under general anesthesia with endotracheal intubation and planned extubation in the operating room will be prospectively enrolled. Patients will be included if pre-extubation RSBI, TOF ratio, and BIS measurements can be obtained and if they provide written informed consent.

Ages

18 to 80 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
