Neurophysiological basis of EEG interpretation appears to day stil poor; conversely mathematical and computerized management of EEG waveform is well documented. To quantify the signal two main procedures are now used: spectral analysis of frequency and aperiodic analysis. ⋯ The knoledge of genuine activity of anesthesic drugs on neuron and neurologia metabolism, local cerebral blood flow and/or neuromediators concentration is not wider than EEG neurophysiological basis. So that, more than the EEG signal itself, alterations of its stability allows specific monitoring for anesthesia which could be more beneficial than others to day usual.

[Psychiatric problems and sleep disorders in surgical intensive care. A polygraphic study: 8 cases].
The patients hospitalized in intensive care units present sleep disorders, mainly a sleep deprivation, particularly in paradoxical sleep. Both on the experimental and clinical plan sleep deprivation has been considered to be responsible for psychotic disorders. Over the past fifteen years these results have been controversial. ⋯ Analysis of these eight cases corroborates the latest experimental résults on sleep deprivation and current methodological considerations. Sleep deprivation in itself does not seem to lead to major psychiatric disorders but it is one of the factors, contributing to genesis of psychiatric troubles in an intensive care unit. The other ones that have been suggested (environment, somatic pathology, psychological ill effects due to the hospitalization) are also quite important.
