Correlation of bispectral index (BIS) monitoring and end-tidal sevoflurane concentration in a patient with lobar holoprosencephaly

Abstract

The BIS is a very useful monitoring tool for assessing the degree of depth of anesthesia and to analyze the electroencephalographic variations of anesthetics. Particular attention should be given to patients with congenital disorders of the central nervous system in which the BIS may give abnormal responses that do not reflect an accurate assessment of the depth of anesthesia.

Propofol-Induced Frontal Cortex Disconnection: A Study of Resting-State Networks, Total Brain Connectivity, and Mean BOLD Signal Oscillation Frequencies

“…However, future studies should study the process of frontal disconnection in more detail to be able to improve the sensitivity of the technique. Furthermore, as different anesthetics might use different pathways to disturb consciousness, frontal EEG monitoring could be less effective for certain anesthetics (Anderson and Jakobsson, 2004;Galante et al, 2015;Lee et al, 2013b;Punjasawadwong et al, 2014).…”

“Early detection of brain death using the Bispectral Index (BIS) in patients treated by extracorporeal cardiopulmonary resuscitation (E-CPR) for refractory cardiac arrest”

“…Thus, for prevention of vaso-constriction and shivering, anesthetics and sedatives were undertaken during therapeutic hypothermia in adult and pediatric patients after cardiac arrest. The BIS is a parameter derived by electroencephalography (EEG) which provides a direct measurement of the effects of sedatives and anesthetics on the brain and offers guidance on the adequacy of anesthesia [3]. However, an important question is raised: the value of BIS during mild therapeutic hypothermia and E-CPR was not true while sedatives and anesthetics were undertaken for patients after cardiac arrest.…”

Processed EEG from depth of anaesthesia monitors and seizures: A scoping review

“…7 case reports were identified documenting the pEEG parameters from depth of anaesthesia monitoring during clinical seizures or epileptiform appearances on EEG [29,[31][32][33][34][35][36]. These were during anaesthetic induction or the operative phase.…”
