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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Bronchoscopy lets doctors look inside the airways to diagnose and treat lung diseases, and deep sedation can make the procedure more comfortable and efficient. Deep sedation also carries risks, including low oxygen levels and airway blockage. This study observes whether giving a breathing tube before deep sedation, with the proceduralist directing the sedation, keeps oxygen levels stable during advanced bronchoscopy. Researchers will track 191 patients with lung disease who need a bronchoscopy-assisted procedure.

What this could mean

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

Active substance
deep sedation with pre-emptive endotracheal intubation during bronchoscopy
What this could lead to
If the approach proves safe and workable, it could give hospitals a clearer way to keep oxygen levels stable during complex bronchoscopy procedures.
What could go wrong
This is an observational study, so it cannot prove the approach causes better outcomes. Results from 191 patients at multiple centers may not apply everywhere, and deep sedation carries known risks of breathing problems.
