NCT ID NCT07003061

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 Results may not be published yet.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

Summary

This study looked at 100 adults having gastrointestinal cancer surgery to see if sarcopenia (muscle loss) changes how muscle relaxants work during anesthesia. Patients were grouped based on CT scans showing sarcopenia. The researchers measured how fast the relaxants worked, how deep the muscle relaxation was, and how long it lasted. The goal is to help doctors personalize anesthesia for safer surgery.

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 study could help anesthesiologists adjust muscle relaxant doses for patients with sarcopenia, improving safety during surgery.
What could go wrong
This is a small observational study, not a treatment trial. It only measures effects during surgery and does not test any new drug or therapy.
