The current clinical practice of balanced anesthetic technique has obscured many of the
observed physiologic parameters that once indicated the depth of anesthesia …

Up-and-coming techniques have the potential to better clinically define and characterize
altered consciousness time points. Such new techniques used alongside traditional …

Background: For decades, monitoring depth of anesthesia was mainly based on unspecific
effects of anesthetics, for example, blood pressure, heart rate, or drug concentrations. Today …

Direct and indirect inhibitory effects of anaesthetic agents on cortical activity are reflected in
the electroencephalogram (EEG) as:(i) a shift from low-amplitude, high-frequency EEG, to …

Current processed EEG monitors are limited by their calibration range and the interpatient
variability in their dose–response curves. The next generation of depth-of-anesthesia …

British Journal of Anaesthesia| CEPD Reviews| Volume 3 Number 4 2003 107 processed
EEG technologies. First, different anaesthetic agents generate different EEG patterns or …

The aim of this chapter is to discuss some of the recent findings on monitoring the depth of
anaesthesia, both in general and with respect to α2-agonists. Defining the depth of …

To date, there has been no satisfactory measure of the adequacy of anesthesia. Intuitively, it
is reasonable to expect that information contained in the electroencephalogram, the …

Depth of anaesthesia monitors can fail to detect consciousness under anaesthesia, primarily
because they rely on the frontal EEG, which does not arise from a neural correlate of …

Monitoring the level of consciousness during general anesthesia with processed
electroencephalogram (EEG) monitors has become an almost routine practice in the …
