Comparison of Acceleromyography and Electromyography in Obese Patients Undergoing General Anesthesia
Sponsor: University of Padova
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.

Conditions
Interventions
Neuromuscular monitoring with electromyography (EMG)
Neuromuscular function will be assessed using an electromyography device applied to the hand. The device measures the electrical activity of muscles in response to ulnar nerve stimulation to calculate the Train-of-Four (TOF) ratio.
Neuromuscular monitoring with acceleromyography (AMG)
Neuromuscular function will be assessed using an acceleromyography device applied to the hand. The device measures the acceleration of thumb movement in response to ulnar nerve stimulation to calculate the Train-of-Four (TOF) ratio.
