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

Assessing the correlation between the train-of-four (TOF) obtained from the 2 devices,Assessing the correlation between the posttetanic count (PTC) obtained from the 2 devices

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.
