Background. Power spectral analysis is a well-established method for the analysis of EEG
signals. Spectral parameters can be used to quantify pharmacological effects of …

The use of EEG monitors to assess the level of hypnosis during anaesthesia has become
widespread. Anaesthetists, however, do not usually observe the raw EEG data: they …

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

Even today many anaesthesiologists rely on parameters of the autonomic nervous system,
such as blood pressure and heart rate to decide if a patient is adequately anaesthetized. It is …

In clinical practice, indirect and non-specific signs are used for monitoring anaesthetic
adequacy. These include haemodynamic, respiratory, muscular and autonomic signs. These …

We have compared the auditory evoked potential index (AEPIndex) and bispectral index
(BIS) for monitoring depth of anaesthesia in spontaneously breathing surgical patients …

Methodology for assessment of depth of anaesthesia based on analysis of the
electroencephalogram (EEG) is controversial. Techniques range from display of single …

THE electroencephalogram (EEG) is enjoying a renaissance of interest as a clinical
monitoring tool during anesthesia and sedation. This revival is the result of two recent …

In 14 patients undergoing elective surgery the EEG was studied during anaesthesia with
isoflurane and nitrous oxide (in oxygen) at 1.3 and 1.5 MAC. The distributions of spectral …

Background 'Depth of anaesthesia'monitors claim to measure hypnotic depth during general
anaesthesia from the EEG, and clinicians could reasonably expect agreement between …
