BACKGROUND: It is important that the level of general anaesthesia (GA) is appropriate for
the individual patient undergoing surgery. If anaesthesia is deeper than required to keep a …

Background The incidence of intraoperative awareness with explicit recall is 1-2/1000 cases
in the United States. The Bispectral Index monitor is an electroencephalographic method of …

Background Anaesthetic drugs during general anaesthesia are titrated according to
sympathetic or somatic responses to surgical stimuli. It is now possible to measure depth of …

IMPLICATIONS: Entropy is a new form of intraoperative consciousness monitoring that has
potential advantages over Bispectral Index. In this report we present a case of a patient …

Background This multicenter study evaluated the effect of a new depth of anesthesia-
monitoring device based on time-frequency-balanced spectral entropy of …

Background Unintended intraoperative awareness, which occurs when general anesthesia
is not achieved or maintained, affects up to 1% of patients at high risk for this complication …

Intraoperative awareness is a very serious complication of general anesthesia. Several
studies have evaluated the potential association between bispectral index (BIS) and …

Background The bispectral index parameter is used to guide the titration of general
anesthesia; however, many studies have shown conflicting results regarding the benefits of …

Background Awareness is an uncommon complication of anaesthesia, affecting 0· 1–0· 2%
of all surgical patients. Bispectral index (BIS) monitoring measures the depth of anaesthesia …

Achieving adequate depth of anaesthesia during surgical procedures is desirable.
Therefore, assessment and monitoring/measurement of the depth of anaesthesia are …
