What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether using ultrasound before and after surgery can help predict difficult breathing tube placement in obese patients. It will compare standard checks with ultrasound measurements and test different types of laryngoscopes. The goal is to improve safety and reduce complications during intubation.

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 safer intubation methods for obese patients by using ultrasound to predict difficulties.
What could go wrong
This is an early-stage observational study, not a treatment trial. Results may not apply to all patients or settings.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

Participants

About 180 people

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Jul 2026

An estimate. End dates often move.
