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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are studying whether the amount of a muscle relaxant called rocuronium affects how well a laryngeal mask airway works during general anesthesia. The laryngeal mask is a soft tube placed in the throat to help patients breathe, an alternative to a traditional breathing tube. In this trial, 96 adults having short elective surgeries are randomly assigned to receive no rocuronium or one of two doses before the mask is placed. The team measures how well the mask seals against the airway and tracks insertion success, breathing measures, and any airway complications.

What this could mean

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

Active substance
rocuronium, a muscle relaxant given before placing a breathing tube alternative called a laryngeal mask
What this could lead to
If it works, this could help anesthesiologists choose the right dose of muscle relaxant to make laryngeal mask insertion easier and ventilation more reliable during surgery.
What could go wrong
This is a small, single-center study of 96 people having short elective surgeries, so the results may not apply to everyone or to longer or more complex operations. Muscle relaxants can cause prolonged weakness or allergic reactions, though these are uncommon.
