Background The index of consciousness (IoC), the permutation entropy (PE), and the
approximate entropy are recent EEG-derived indices of anaesthetic depth. In this study, a …

Accidental awareness during anaesthesia, especially with pain and subsequent recall of the
event, is a terrifying prospect. A high proportion of those who experience it are reported to go …

This paper presents a new index to measure the hypnotic depth of anaesthesia (DoA) using
EEG signals. This index is derived from applying combined Wavelet transform, eigenvector …

Without any doubt there is an increasing need for accurately measuring depth of anesthesia-
from the viewpoint of the anesthesiologist and also of the patient. The ideal monitoring …

Background. Patient state index (PSI) and bispectral index (BIS) are values derived from the
EEG, which can measure the hypnotic component of anaesthesia. We measured the ability …

BACKGROUND It is claimed that bispectral index (BIS) and state entropy reflect an identical
clinical spectrum, the hypnotic component of anaesthesia. So far, it is not known to what …

The first attempts to introduce computerized power spectrum analysis of the
electroencephalogram (EEG) as an intraoperative anaesthesia monitoring device started …

In the last few years, several monitors have been developed to assess the depth of
anaesthesia and to discriminate between its pharmacodynamic components. Most of those …

Background The isolated forearm test (IFT) is the gold standard test of connected
consciousness (awareness of the environment) during anaesthesia. The frontal alpha-delta …

Study Objectives: To examine the impact on perioperative care of routine Bispectral Index
(BIS) monitoring during general anesthesia throughout an entire operating room (OR) suite …
