Five Cases of Near-Miss Sudden Infant Death Syndrome and Development of Obstructive Sleep Apnea Syndrome

Abstract
Five full-term [human] infants were referred for near-miss sudden infant death syndrome events, which occurred between 3 and 12 wk of age. After a complete pediatric evaluation and 24-h polygraphic monitoring, each infant was monitored at home with a cardiorespiratory monitor. Each was followed regularly (with repeat polygraphic recordings) up to 4 yr of age. All 5 infants developed heavy snoring at night and symptoms of obstructive sleep apnea syndrome. Diagnosis of obstructive sleep apnea syndrome was confirmed by polygraphic recordings; surgery was recommended. Of the 5 children, 4 underwent adenoidectomies between 3 and 4 yr of age, and this significantly improved their condition. These 5 cases are the 1st polygraphically documented histories of the development of obstructive sleep apnea syndrome.
