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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tested whether ultrasound measurements of the airway can better predict difficult intubation (placing a breathing tube) than standard physical exams. Researchers compared ultrasound images of the throat and neck with traditional tests like mouth opening and neck movement in 420 adults having surgery. The goal was to see if ultrasound could more accurately identify patients who might have trouble with intubation, potentially improving safety.

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 more accurate, non-invasive way to predict difficult intubation, potentially reducing complications during anesthesia.
What could go wrong
This is an observational study, not a treatment trial. The findings may not apply to all patient groups, and ultrasound requires training and equipment not always available.

Who can take part

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

Who is studied

All cases that meet the inclusion and exclusion criteria will be included in the study. Patients will be taken to the operating room after being preoperatively evaluated in the observation room. The patient's anesthetic management will be provided by another anesthesiologist who is not participating in the study and is responsible for the patient. Intraoperative data will be obtained from the patient's anaesthesia follow-up form and the records of the anaesthesia machine. This group will include patients who will be intubated and operated on under general anaesthesia.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Patients to be operated with endotracheal intubation under elective conditions * Voluntary patients whose informed consent was obtained, * Patients older than 18 years * Patients evaluated in the 1-2-3 category of the American Society of Anaesthesiologist (ASA) Exclusion Criteria: * Patients with a history of difficult intubation * Pregnant patients * Patients with a history of surgery in the head and neck region * Patients with a history of trauma or tumour in the head and neck region * Presence of a syndrome that will cause difficult intubation * Uncooperative patients, * Patients with missing data
