Comparison of Acceleromyography and Electromyography in Obese Patients Undergoing General Anesthesia

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.
