title: [Sleep apnea syndrome in intensive care].
abstract: The aim of this work was to study the existence of special characteristics in the sleep apnoea syndrome (SAS) discovered following a stay on the Intensive Care Unit. This retrospective study of 25 casenotes of SAS patients who were resuscitated has enabled a comparison with 182 SAS patients who have never had acute respiratory failure. The intensive care consisted of controlled ventilation, following intubation, in a clinical context of acute respiratory failure with major problems of conscious level. The diagnosis of SAS was made using conventional or computerised polysomnography, or a computerised study of transcutaneous SaO2 (SaO2TC) which had been validated before. The results show that patients with SAS in an Intensive Care Unit, differs significantly from other patients with SAS by the permanent presence of alveolar hypoventilation in a stable state, associated with a significant decrease in the FEV1 (VEMS) in relation to the group that had not been in intensive care. However, the FEV1/VC ratio did not differ between the two groups which were expressed in absolute values or as a percentage of the theoretical value defined on the basis of their age. There was no difference on the data from the sleep studies and notably the hypoapnoeic indices, nor on age, the index of body mass or the sex ratio. We conclude that there is a need to look for SAS in the presence of acute respiratory failure in the obese without a recognised cause.
