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 Results may not be published yet.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.

Summary

This study looks at whether measuring the airway with ultrasound before surgery can help predict if placing a breathing tube using a video laryngoscope will be difficult. Researchers will compare ultrasound measurements to a standard difficulty score in 100 adults aged 18 to 80 undergoing general anesthesia. The goal is to find a non-invasive way to identify patients who might have a challenging intubation, potentially improving safety and planning.

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 help anesthesiologists better predict difficult intubations before surgery, potentially improving patient safety.
What could go wrong
This is an observational study, not a treatment trial. It may not find a strong link between ultrasound measurements and intubation difficulty, limiting its practical use.
