Novel Methods for Measuring Depth of Anesthesia by Quantifying Dominant Information Flow in Multichannel EEGs

Abstract: In this paper, we propose novel methods for measuring depth of anesthesia (DOA) by quantifying dominant information flow in multichannel EEGs. Conventional methods mainly use few EEG channels independently and most of multichannel EEG based studies are limited to specific regions of the brain. Therefore the function of the cerebral cortex over wide brain regions is hardly reflected in DOA measurement. Here, DOA is measured by the quantification of dominant information flow obtained from principle bipartition. … Show more

“…Poor assessment of anaesthetic depth (AD) during general anaesthesia can result to overdosing or underdosing of the anaesthetic agent 1 2. In the context of anaesthetic agent overdose, extreme AD has been associated with an increased risk of mortality,3–6 intraoperative hypotension and hypoperfusion of heart and brain,7 perioperative nausea, vomiting and delirium 7–10. In the case of low dosage, there have been reports of intraoperative awareness, with an incidence of 0.1%–0.2%, approximately 26,000 cases per year in the USA 11 12…”

“…1 2 In the context of anaesthetic agent overdose, extreme AD has been associated with an increased risk of mortality, [3][4][5][6] intraoperative hypotension and hypoperfusion of heart and brain, 7 perioperative nausea, vomiting and delirium. [7][8][9][10] In the case of low dosage, there have been reports of intraoperative awareness, with an incidence of 0.1%-0.2%, approximately 26,000 cases per year in the USA. 11 12 Assessment of AD through clinical signs such as state of consciousness, limb movement, heart rate, pupil size, blood pressure, arterial blood oxygen and perspiration is used in general anaesthesia because it reflects the activity of the autonomic nervous system (ANS) and central nervous system (CNS).…”
