TetraGraph Poster and Abstract presentation at The Society for Technology in Anesthesia (STA) 2018
During the meeting, Reka Nemes, MD, Mayo Clinic, Jacksonville, Florida presented an abstract and poster entitled, “Comparison of electromyography derived train-of-four ratios of the adductor pollicis and abductor digiti minimi muscles and their comparison to acceleromyography derived train-of-four ratios.”
The pilot study investigated the TetraGraph, an electromyography (EMG)-based monitor that uses proprietary surface strip electrodes (TetraSens) for ulnar nerve stimulation, while recording compound muscle action potentials from the adductor pollicis (mAP) or the abductor digiti minimi (mADM) muscles. The study aim was to compare the correspondence of the two hand muscles’ EMG-derived TOF ratios (%), and to examine the agreement between EMG and acceleromyographic (AMG) measurements.
Unlike AMG-based monitors, the TetraGraph is able to record multiple different hand muscles such as the mAP and mADM. These recordings were easy to perform with the TetraGraph, and confirmed that these muscles have different onset and recovery times. Knowing which muscle is being monitored has important clinical implications on the appropriate timing of reversal of neuromuscular block.
