The latest trend in neuromuscular monitoring: return of the electromyography

摘要

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.
