NCT ID NCT07077317

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 Results may not be published yet.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 study looked at over 1,000 adults having surgery to see if common checks like neck size, mouth opening, and a sleep apnea questionnaire can predict breathing tube difficulties. Researchers tracked mask ventilation, laryngoscopy, and intubation problems, plus serious breathing events after surgery. The goal is to improve safety by identifying high-risk patients before anesthesia.

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 identify patients at risk for airway complications, potentially reducing serious breathing problems during surgery.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly improve care. Results may not apply to all patient groups or surgical settings.
