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 Results may not be published yet.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.

Summary

This study looks at how often pain occurs in intensive care unit (ICU) patients who are on mechanical ventilators (breathing machines). Researchers will observe 370 adults, using special pain scales to measure pain on the second day of ventilation and when they first wake up. They will also track breathing problems, time on the ventilator, and death rates over 28 days to see if pain is linked to worse outcomes.

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 better recognize and manage pain in sedated ICU patients, potentially improving recovery and reducing complications.
What could go wrong
This is an observational study, not a treatment trial. It only measures pain and outcomes, so it won't directly change care. Results may not apply to all ICU settings.

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

Show the full entry requirements

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

Inclusion Criteria Participants of both sexes, aged 18 or over; Participants who are using invasive mechanical ventilation, Exclusion Criteria: Participants undergoing treatment with neuromuscular blockers,; Participants with any condition associated with altered pain perception (e.g., Guillain-Barré Syndrome, SCI, etc.); Participants with any condition that would likely interfere with behavioral assessments of pain (e.g., decortication or decerebration posture) As the assessments will be carried out before and after the tracheal aspiration procedure, if the patient does not have objective criteria for tracheal aspiration, he/she will be excluded from the study, irrefutably preventing the procedure from being carried out without express need.
