NCT ID NCT07283354

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 Results may not be published yet.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

Summary

This study will compare two devices that measure muscle relaxation during anesthesia in 30 obese patients having weight-loss surgery. One device tracks thumb movement (AMG), the other measures muscle electrical signals (EMG). The goal is to see which is more accurate for guiding the reversal of muscle relaxants, potentially improving safety and recovery.

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 choose the best monitoring method for obese patients, improving safety and recovery after surgery.
What could go wrong
This is a small observational study (30 people) that does not test a new treatment, so its findings may not apply to all patients or change practice immediately.
