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 Results may not be published yet.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

Summary

This study will check if a simple lung ultrasound done before, during, and after surgery can predict who will need extra oxygen or develop lung complications. Researchers will follow 97 adults having major non-chest surgery. The goal is to see if the ultrasound score is linked to early oxygen needs and problems like pneumonia or collapsed lungs.

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 give doctors a simple bedside tool to predict which patients need extra oxygen or may develop lung complications after surgery.
What could go wrong
This is a small observational study, not a treatment trial. It only looks at prediction, so it won't change care directly. Results may not apply to all surgery types.
