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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study observes 600 adult patients after major surgery to see if simple bedside tests—like ultrasound of breathing muscles and a breathing score—can predict who will need a breathing tube again. No new treatments are given; doctors make all decisions as usual. The goal is to find better ways to spot high-risk patients early.

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 predict which patients might need to be put back on a breathing tube after surgery, potentially reducing complications.
What could go wrong
This is an observational study, so it only looks for patterns—it does not test a treatment. The findings may not lead to a clear prediction tool or change clinical practice.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult postoperative patients aged 18 years and older who are admitted to the anesthesia and reanimation intensive care units after major surgery, including abdominal, vascular, orthopedic, and ear, nose, throat, head and neck surgery. Eligible patients will be those extubated in the operating room and admitted to the intensive care unit with spontaneous breathing during the study period after ethics committee approval.

Inclusion Criteria: Adult patients aged 18 years and older Patients requiring postoperative intensive care follow-up after major surgery, including abdominal, vascular, orthopedic, or ear, nose, throat, head and neck surgery Patients extubated in the operating room and admitted to the intensive care unit with spontaneous breathing Patients without any clinical condition preventing the planned measurements within the first 0-2 hours after ICU admission (T0 and T1) Patients for whom written informed consent can be obtained from the patient or legally authorized representative Patients admitted to the intensive care unit within the specified study period after ethics committee approval and enrolled consecutively Exclusion Criteria: Patients younger than 18 years of age Patients who leave the operating room intubated or are admitted to the intensive care unit while intubated Patients with a tracheostomy Patients with a history of diaphragmatic paralysis Patients with a significant neuromuscular disease, such as ALS, myasthenia gravis, or similar conditions Patients with conditions that significantly prevent ultrasound measurements, including marked subcutaneous emphysema, large dressings or bandages covering the measurement area, inability to access the measurement site due to drains or the surgical field, or inability to obtain technically adequate images Patients in whom the planned measurements cannot be performed due to clinical instability requiring emergency intubation immediately after ICU admission Patients from whom informed consent cannot be obtained, or patients or legally authorized representatives who refuse participation
