title: [Obstructive apnea and periodic respiration in premature infants].
abstract: BACKGROUND
  Disturbances of cardiorespiratory function are common clinical problems in preterm infants. Polygraphic recordings during sleep were performed in order to determine frequency and severity of idiopathic apnea of prematurity.
  
  
  METHODS
  In 137 preterm infants at the corrected age of < +/- 0 weeks, 0-12 weeks, 13-24 weeks and > or = 25 weeks respectively central and obstructive apnea and periodic breathing were recorded by polysomnography including nasal airflow and thoracic and abdominal breathing movements and compared with 50 normal full-term infants.
  
  
  RESULTS
  Apnea frequency was inversely correlated to gestational age in premature and term infants. Whereas no differences were found concerning central apnea and periodic breathing, obstructive apnea occurred more frequently in premature than in term infants during the first weeks of life.
  
  
  CONCLUSIONS
  Conclusively, in early infancy premature infants have an inclination to upper airway obstruction.
