Obstructive sleep apnea in young infants.

Obstructive sleep apnea (OSA) was diagnosed in 14 infants less than 18 months of age. Snoring, apnea, failure to thrive, developmental delay and recurrent respiratory infections were the main presenting symptoms. The diagnosis was made by polysomnographic studies or overnight monitoring. Adenotonsillectomy resulted in the relief of symptoms and signs in 13 children. In one infant prolonged nasopharyngeal intubation was needed. An increased awareness of OSA in young infants may prevent the delay in diagnosis, will allow early treatment and thus prevent the development of sequela or complications associated with this syndrome.
