This study will evaluate whether gentle skin abrasion improves electromyographic signal quality during neuromuscular blockade monitoring in adult surgical patients.
Participants will receive standard TwitchView electromyographic neuromuscular blockade monitoring on one wrist and TwitchView monitoring after gentle skin abrasion on the opposite wrist. The study will compare electromyographic response amplitudes and supramaximal stimulus currents between routine electrode application and electrode application after skin preparation.
The study procedures will occur during scheduled surgery and will not alter the anesthetic or surgical management of participants.
