The train-of-four (TOF) ratio is a quantitative measure used in anesthesia to assess the degree of neuromuscular blockade induced by neuromuscular blocking agents during surgical procedures. Current American Society of Anesthesiologists guidelines recommend monitoring the TOF ratio to guide the administration and reversal of NMBAs, with a target ratio of 0.9 or higher at adductor pollicis muscle indicating adequate reversal and restoration of neuromuscular function. This proposed study aims to observe and compare the TOF ratio between two different muscles of the hand: adductor pollicis and adductor digiti minim using anesthesia monitors on both of their arms during recovery of neuromuscular function. Surgery and anesthesia will occur per standard of care.
