title: [Neurovegetative symptoms in infants with sleep-related respiratory disorders].
abstract: A relationship between neurovegetative symptoms and an increased risk of sudden infant death (SID) has been frequently described. Such symptoms are vomiting because of gastroesophageal reflux, breathing disorders while nutritive sucking, excessive sweating during sleep, prolonged apneas and apneas with associated symptoms, further unexplained episodes of cyanosis, pallor and loss of muscle tone. An acute decompensation of the cardiorespiratory autonomic system during sleep is currently discussed to be one of the causes of SID. Polysomnographic investigations are used to diagnose sleep related cardiorespiratory autonomic dysfunction. In this study, infants up to the age of 5 months were examined using polysomnography throughout their entire nocturnal sleep. The findings from 79 infants with neurovegetative symptoms were compared with the results from 163 healthy control children. Indications of an impaired respiratory regulation during sleep were shown to be significantly more frequent in infants with neurovegetative symptoms. In particular the occurrence of periodic breathing with a high frequency of periodic apnea plus a large number of acute decreases in oxygen saturation could be shown in infants with neurovegetative symptoms. The findings were most pronounced during the first 1.5 months after birth. The results of this investigations lead to the conclusion that, in the case of young infants with breathing abnormalities, neurovegetative symptoms can frequently be observed. The occurrence of such symptoms should therefore be a reason for a polysomnographic examination.
