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 Results may not be published yet.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.

Summary

This study is testing whether giving patients 30%, 50%, or 80% oxygen during and right after major surgery can reduce wound infections and other complications. About 7,800 adults having surgery lasting at least 2 hours will take part. The goal is to find the best oxygen level to improve recovery and reduce infections.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
oxygen
What this could lead to
If it works, this could show that giving more oxygen during surgery lowers the chance of wound infections and helps patients recover faster.
What could go wrong
This is a Phase 4 study, but results may not apply to all surgeries. Higher oxygen might also increase lung complications, so the risks are being carefully weighed.
