Study Comparing a New Wireless Electromyography and Acceleromyography Neuromuscular Monitor With the Standard TOF-Watch Device During Surgery

What this Trial Is About

Researchers are evaluating a new device that combines electromyography EMG and acceleromyography AMG signals to monitor neuromuscular block during surgery. This study aims to compare the new technology with the TOF Watch4 SX, a widely used AMG-based neuromuscular monitor, to assess its accuracy in measuring neuromuscular block and posttetanic count. The new devices reliability has been recognized in rehabilitation but has not yet been tested for neuromuscular monitoring in surgery. The study involves observing patients undergoing elective surgery requiring muscle relaxation. The two monitored methods are the existing TOF Watch4 SX AMG device and the new DELSYS4 Wireless surface EMG technology, which captures both EMG and AMG signals wirelessly. Researchers will compare the train-of-four TOF and posttetanic count PTC measurements obtained from these devices during the perioperative period. Participants will be assessed during surgery with neuromuscular monitoring devices. Data collected include TOF and PTC correlations between the two devices and analysis of signal sources to improve monitoring. The study is observational, with no treatment changes, and aims to validate this new monitoring method. Participants will be adults aged 18 to 90 undergoing elective surgery with muscle relaxation, with safety and monitoring overseen throughout the procedure.
