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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looked at whether suctioning the windpipe (tracheal suction) during removal of a breathing tube affects lung volume in critically ill patients. Researchers measured lung volume changes in 60 ICU patients before and after extubation, comparing those who received suction to those who did not. The goal was to understand if this common procedure causes lung deflation, which could inform better extubation practices.

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 help doctors decide whether to use tracheal suction during extubation to protect lung function in ICU patients.
What could go wrong
This is a small, completed study with only 60 participants. It measured short-term lung volume changes, not long-term outcomes, so results may not apply broadly.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * age of 18 years or more * hospitalization in the surgical ICU (whatever the cause of hospitalization) * under mechanical ventilation via a tracheal tube (oro or nasotracheal) for at least 24 hours * satisfying general criteria for mechanical ventilation weaning (described by the French Language Resuscitation Society) * having successfully completed a spontaneous breathing trial (among those described by the SRLF) * physiotherapist available during the first hour after extubation Exclusion Criteria: * the presence of an electrical implantable medical device (pacemaker, automatic defibrillator, deep brain stimulation box) * body mass index (BMI) \> 50 * pregnancy * tracheal tube with subglottic suction channel * technical impossibility of monitoring by electrical impedance tomography (chest plaster, undrained pneumothorax, ...).
