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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether using a bedside ultrasound to guide throat suctioning can reduce lung infections and injuries in ICU patients on breathing machines. About 321 adults expected to need a breathing tube for at least 72 hours will take part. The goal is to see if this imaging technique makes the procedure safer and more effective.

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

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: * 1\. Patients admitted to the ICU with the patient or their legal representative having signed an informed consent form; 2. Patients expected to have an oral artificial airway in place for ≥72 hours; 3. Patients using tracheostomy tubes with subglottic suctioning Exclusion Criteria: * 1\) Severe cervical deformity, extensive subcutaneous emphysema, thick dressing coverage, or severe obesity that prevents clear visualization of the subglottic region by ultrasound. 2\) Coagulopathy (platelets \<50×10⁹/L) or active bleeding tendency, which may induce airway bleeding due to suctioning procedures. 3\) Presence of organic airway disease or previous cervical surgery history, affecting assessment of the subglottic region. 4\) Tracheostomy patients. 5) Patients allergic to ultrasound coupling agents, or those unable to cooperate with cervical ultrasound examination due to severe agitation. 6\) Patients with existing pulmonary infection upon admission. 7) Patients intubated for treatment of known aspiration. 8) History of lung cancer or head and neck cancer that may produce alpha-amylase in the lungs. 9\) History of conditions affecting salivary secretion (e.g., Sjögren's syndrome).
