Key result
Newly developed electromyography-based neuromuscular monitoring devices are recommended because they provide accurate measurements and overcome the limitations of acceleromyography.
Why the study?
Acceleromyography-based neuromuscular monitoring has issues with patient posture and overestimation of train-of-four ratio, leading to renewed attention toward electromyography-based monitoring.
Does electromyography (EMG)-based neuromuscular monitoring improve accuracy and usability compared to acceleromyography (AMG)-based monitoring in patients undergoing anesthesia?
Does electromyography (EMG)-based neuromuscular monitoring improve accuracy and usability compared to acceleromyography (AMG)-based monitoring in patients undergoing anesthesia?
EMG-based neuromuscular monitoring is gaining renewed attention as it overcomes the limitations of AMG, such as TOF overestimation and posture restrictions during modern surgeries.
Supports EMG neuromuscular monitoring for accuracy; leaves open validation in randomized trials before practice change.
To reduce the risk of residual neuromuscular blockade, neuromuscular monitoring must be performed. Acceleromyography (AMG)-based neuromuscular monitoring was regarded as "clinical gold standard" and widely applied. However, issues related to patient's posture and overestimation of train-of-four ratio associated with AMG-based neuromuscular monitoring have increased. Recently, electromyography (EMG)-based neuromuscular monitoring is receiving renewed attention, since it overcomes AMG's weaknesses. However, both AMG-based and EMG-based systems are useful when certain considerations are followed. Ultimately, to assure the patient's good outcomes, the choice of monitoring system is not as important as the monitoring itself, which should be always implemented in such patients.

Wonjin Lee (2021) conducted a review in Residual neuromuscular blockade. Electromyography (EMG)-based neuromuscular monitoring vs. Acceleromyography (AMG)-based neuromuscular monitoring was evaluated. Newly developed electromyography-based neuromuscular monitoring devices are recommended because they provide accurate measurements and overcome the limitations of acceleromyography.
