Abstract

The GE Entropy module is used to monitor depth of consciousness via analysis of forehead electroencephalogram (EEG) and electromyography (EMG). We report a case series where the placement of entropy monitors prevented EMG neuromonitoring intraoperatively. The entropy module caused inconsistent fluctuations in the EMG, which may be due to the overlapping power spectra between EEG and EMG in the frequency range of 10 to 50 Hertz (Hz). We will discuss the mechanisms of entropy monitoring and EMG, possible causes of interference, and alternative options to entropy monitoring when interference with EMG occurs.
