Polysomnographic and clinical findings in children with obstructive sleep apnea
1Department of Otolaryngology, University of Texas Southwestern Medical School, Dallas 75235.
Insights
This study found that while children with obstructive sleep apnea (OSA) often present with cor pulmonale, tonsil hypertrophy, and failure to thrive, obesity was not a significant factor. Further research is needed to identify all risk factors for pediatric OSA.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Clinical Research
Background:
- Obstructive sleep apnea (OSA) is a common condition in children.
- Identifying children at higher risk for OSA is crucial for timely diagnosis and intervention.
- Polysomnography is the gold standard for diagnosing pediatric OSA.
Purpose of the Study:
- To identify clinical characteristics and comorbidities associated with obstructive sleep apnea (OSA) in children.
- To determine which polysomnographic findings are most compatible with OSA in pediatric patients.
Main Methods:
- Retrospective chart review of 93 children aged 18 months to 12 years with symptoms suggestive of OSA.
- Analysis of presenting symptoms, associated illnesses, and physical findings (height, weight, tonsil size).
- Evaluation of polysomnography results to confirm OSA diagnosis.
Main Results:
- Of 93 children evaluated, 34 (36.6%) met polysomnography criteria for OSA.
- Cor pulmonale, tonsil hypertrophy, and failure to thrive were significantly associated with OSA.
- Obesity was surprisingly not found to be significantly associated with OSA in this cohort.
Conclusions:
- Specific clinical indicators like cor pulmonale, tonsil hypertrophy, and failure to thrive are associated with pediatric OSA.
- Age, sex, and general symptoms were not significant predictors differentiating OSA from non-OSA groups.
- Further investigation into the diverse risk factors for pediatric obstructive sleep apnea is warranted.
Abstract:
A retrospective study was conducted to determine which types of children might have polysomnographic findings that are most compatible with obstructive sleep apnea (OSA). The charts of 93 patients who were aged 18 months to 12 years were examined. All 93 patients had symptoms that were initially suggestive of OSA, and they underwent polysomnography. The types of presenting symptoms and associated illnesses were noted. Physical findings, including height, weight, and tonsil size, were examined. Of 93 patients with symptoms that were suggestive of OSA, 34 met sleep study criteria for OSA. In 44 patients, OSA was not demonstrated, and 15 patients had other results. On the basis of age, sex, and symptoms, no significant differences could be found between the group with OSA and the group with normal polysomnographic findings. Cor pulmonale, tonsil hypertrophy, and failure to thrive were associated with OSA. Surprisingly, obesity was not significantly associated with OSA.
