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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are studying whether ultrasound pictures of the neck and mouth can predict a difficult breathing tube placement in adults having elective cancer surgery. The trial compares ultrasound measurements, such as skin-to-epiglottis distance and tongue thickness, with standard bedside airway checks. About 118 patients take part, and doctors grade the view during laryngoscopy to see how well the ultrasound signs match up.

What this could mean

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

Active substance
preoperative airway ultrasound protocol
What this could lead to
If ultrasound proves reliable, anesthesiologists could spot a hard-to-intubate airway before surgery and plan safer breathing tube placement.
What could go wrong
This is a small observational study in cancer surgery patients, so the findings may not apply to other groups. Ultrasound measurements can vary between operators and machines.
