Comparison of an Acceleromyography- and Electromyography-based Neuromuscular Monitor With TOF-Watch ® Monitor

Condition(s) studied

Investigational drug(s) / intervention(s)

TOF-Watch®；DELSYS® Wireless surface EMG: TOF-Watch® is the most widely accepted AMG-based neuromuscular monitor; and DELSYS® Wireless surface EMG is a new technology that allows for the simultaneous acquisition of EMG and AMG signals in a wireless manner.

Study summary

A quantitative neuromuscular monitoring device is desirable to titrate the depth of neuromuscular block (NMB) during a procedure, and to prevent residual effects after removal of the endotracheal tube. Unfortunately, the most widely used monitoring technique acceleromyography (AMG) typically implies a series of cumbersome installation and calibration procedures that frequently precludes correct use of these devices in clinical practice. Electromyography (EMG) has recently attracted a lot of attention as an alternative strategy to compensate for the deficiency of AMG-based neuromuscular monitors. Nowadays, a new technology that allows for the simultaneous acquisition of EMG and AMG signals is commercially available. Although its reliability has been rapidly accepted in Physical Medicine and Rehabilitation, the use of the technique in neuromuscular monitoring has never been reported. The aim of the present study is to assess the validity of the new device for estimating the neuromuscular block by comparing with TOF Watch®-SX, which is the most widely accepted AMG-based neuromuscular monitor that has been practiced in the clinical arena for decades.
