title: [The neuro-anaesthesiology assisted by the electroencephalogram].
abstract: The electrophysiology can be considered as one of the most reliable assessment of the nervous system function during anaesthesia. For instance, the electroencephalogram (EEG) can be relatively easily simplified and adapted to the current practice of the neuro-anaesthesia or neuro-intensive medicine. Since approximately 10 years, some extremely simplified devices have been introduced, but they allowed only inaccurate assessment because of their too global analysis of the brain function. The monitoring of the true digitised EEG, based on a simplified brain mapping montage combined to the analysis in the frequency and the time domains corresponds to a new investigation tool: the simplified EEG or sEEG, which can be included in our usual monitors or anaesthesia and intensive care machines. This new sort of monitoring could give us valuable information about, first, the control of the peroperative consciousness and the nociceptive or not afferent inputs due to surgical stimulations, and, second, the detection of several particular physiopathologic states during neuro-anaesthesia (brain ischaemia, non-convulsive epilepsy, cerebral protection em leader ). These different theoretical and practical topics are reviewed to try to define the possible preliminary rules of the use of the sEEG.
