Introduction: There are few studies in preterm newborn nocturnal sleep. Our goal was to describe the nocturnal sleep architecture and respiratory events associated, like apnea and oxygen saturation in newborn less than 3 months postnatal life. Material and method: 30 newborn ≤ 37 gestation weeks, post-conceptional age ≤ 3 months, not hospitalized, were selected. Through 8 hours nocturnal sleep polisomnographic study they were rated. Results: The gestation weeks median was 34 ± 1.5, the age was 43.5 ± 25.5 at the time of study. The quiet sleep total time was greater than the active sleep total time (Wilcoxon p = 0.411). The central apnea index in active sleep total time (76.2 ± 53.4) was greater than quiet sleep total time (33.6 ± 31.7) Wilcoxon p = 0.026. SaO₂ average median was 93.5%. The 27% of sleep total time we registered intermittent hypoxemia. Conclusions: The presence of intermittent hypoxemia in preterm newborn is a risk condition to cognitive and physical development. Sleeping intermittent hypoxemia early diagnosis and treatment is very important.
