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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 completed trial tested whether using positive pressure while removing the breathing tube (extubation) can prevent low oxygen levels after abdominal surgery. 264 adults undergoing scheduled visceral or urological surgery were randomly assigned to standard extubation or one of two positive pressure techniques. The main goal was to see if positive pressure reduces oxygen drops below 92% during and after the procedure.

What this could mean

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

Active substance
positive pressure during extubation procedure
What this could lead to
If it works, this could lead to a simple change in how patients are taken off the breathing tube after surgery, reducing complications like low oxygen levels.
What could go wrong
This is a single-center study with a moderate number of participants, so results may not apply to all hospitals or patient types. The technique may not show a meaningful benefit over standard care.
