Continuous EEG monitoring in ICU

Abstract

Since 1990, the spread of digital EEG systems has enabled the filtering/refiltering of EEG waveforms, which has allowed EEG waveforms to be presented in a more easily readable format. [...]the advent of quantitative EEG displays, such as density spectral array (DSA) and compressed spectral array (CSA), has allowed us to readily detect seizure by color, instead of waveforms, from long-term EEG data. Performing the procedure on all patients with consciousness disorder will significantly increase the technical burden. Since the numbers of EEG machines and technicians available are always limited, it is necessary to select patients who require CEEG. Diagnosis of NCSE by CEEG EEG terminology Since NCSE does not manifest with overt convulsion, EEG interpretation plays an important role in its diagnosis. [...]long-term EEG monitoring shows that the EEG patterns of patients with consciousness disorder substantially fluctuate both temporally and spatially. In this continuum, EEG patterns also undergo dynamic changes, reflecting repeated secondary nerve injuries. [...]the correct interpretation of EEG findings is very important to enable early therapeutic interventions and thereby prevent nerve injury at as early a stage as possible.
