Among 37 patients that are admitted for a more than 3 days breathing reanimation, 19 are ventilated with bacterial filter Pall BB 22 15 and 18 with Darex Hygrobac, exchanged every days and connected to the Y piece. In this study, 6 patients are ventilated with a humidifier (pilot population). ⋯ The two filters give very good and comparable bacteriological results. The filters prevents nosocomial pulmonary infections making a bacterial frontier between the patient and the respirator and reducing aerial contamination from one patient to another.

A rebreathing closed-circuit (Dräger) has been modified adjoining an automated device to inject volatile anaesthetics, thus replacing the usual vaporizer. The input of anaesthetic drug is separated from that of fresh gases: its rate of administration can thus be maintained precisely. ⋯ In our experiences, this device allows for a very satisfactory regulation of the alveolar concentration of the volatile anaesthetic. In addition, this apparatus is able to measure the injected volume of liquid anaesthetic and includes several devices aimed at increasing both safety and versatility.

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.

To be comatose leads one to physical and psychological distresses which mean meeting an peak vital experience. The authors analyze how patient and family are concerned by the recovery of consciousness in Intensive Care Unit conditions. In order to get a quicker and better recovery, there is a need for interpersonal interaction. This type of approach in this specifical is analyzed.

[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.
