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 Results may not be published yet.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

Summary

Researchers are observing whether the time of day affects how safely and quickly anesthesiologists place breathing tubes in surgical patients. They will compare intubations done during regular daytime hours with those done in the evening, at night, or on weekends. The study tracks complications like multiple attempts or low oxygen, how long each intubation takes, and how sleepy the doctor feels beforehand. About 1,000 adult patients undergoing general anesthesia at a single hospital take part.

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 off-hours intubations prove riskier, hospitals could adjust staffing, fatigue rules, or backup support to make anesthesia safer at night.
What could go wrong
This is an observational study at one center, so it cannot prove cause and effect. Differences between day and night cases may reflect patient mix or other factors rather than shift timing alone.
