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
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 This study
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 Results may not be published yet.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.

Summary

This completed study looked at whether neck ultrasound can help doctors predict when placing a breathing tube (intubation) will be difficult. Researchers observed 246 adult patients who needed general anesthesia with intubation. They measured various neck structures with ultrasound and compared them to the view doctors saw during laryngoscopy. The goal is to find a simple, non-invasive way to prepare for tricky intubations.

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 lead to a simple, non-invasive way to predict difficult intubation before surgery, helping doctors prepare better.
What could go wrong
This is an observational study, not a treatment trial. The results may not apply to all patients, and ultrasound accuracy can vary by operator.
