Comparison of Two Quantitative EMG Monitors for Deep Neuromuscular Block in Laparoscopic/Robotic and VATS Surgery

The main objective of the study is to compare the frequency of intraoperative spontaneous diaphragmatic movements and breath-initiation efforts in participants undergoing robotic and/or thoracic surgery under deep neuromuscular blockade (NMB), using either the TetraGraph or TwitchView applied to the dominant hand. These events will serve as objective indicators to evaluate each device's ability to monitor and maintain adequate deep NMB.
