Comparison of Acceleromyography and Electromyography in Obese Patients Undergoing General Anesthesia
Italy30 participantsStarted 2026-02-01
Plain-language summary
The goal of this prospective observational study is to compare two different methods of monitoring muscle relaxation during anesthesia - acceleromyography (AMG) and electromyography (EMG) - in people with obesity who are having bariatric surgery with general anesthesia and the muscle relaxant rocuronium.
The main question is: Which method is more accurate and precise in measuring the Train-of-Four (TOF) ratio during surgery? As part of this comparison, researchers will also note how quickly each method detects recovery of muscle function after the reversal drug sugammadex.
Participants will:
* Receive standard anesthesia care for bariatric surgery, including rocuronium to relax the muscles.
* Have two small monitoring devices applied, one to each hand: AMG on one hand, EMG on the other.
* Be monitored for muscle function during surgery and after receiving sugammadex to reverse the muscle relaxation.
Researchers will also record how easy each device is to use and whether participants have any breathing problems after surgery.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
