Summary

Processed electroencephalogram (EEG) monitors are routinely used in addition to clinical parameters to assess the depth of anaesthesia during general anaesthesia.

Detailed description

Processed electroencephalogram (EEG) monitors are routinely used in addition to clinical parameters to assess the depth of anaesthesia during general anaesthesia. In addition to the bispectral (BIS) index displayed as an index, the raw frontal EEG can be displayed as a curve on these monitors. After a short training, anaesthetists might be more accurate and faster in assessing depth of anaesthesia by recognizing the pattern of the EEG curve than by using the BIS index. This may further enhance the positive effects that could be demonstrated for the use of BIS monitors. Therefore, the aim of the investigator's study is to investigate the clinical relevance of interpreting the raw frontal EEG in addition to only using the BIS index for titrating intravenous anaesthetics.
