Management and outcomes of obstructive sleep apnea in infants.

ABSTRACT

OBJECTIVE: To characterize the clinical characteristics of infants with obstructive sleep apnea (OSA), define the resolution rate of infant OSA, and identify factors associated with OSA resolution. METHODS: We identified infants diagnosed with OSA via retrospective chart review at less than one year of age at a tertiary care center. We identified patient comorbidities, flexible or rigid airway evaluations, surgical procedures, and oxygen/other respiratory support administration. We identified infants as having resolved OSA based on clinical or polysomnogram resolution. We compared the frequency of comorbid diagnoses and receipt of interventions in infants with resolved versus non-resolved OSA by χ2 analysis. RESULTS: 83 patients were included. Prematurity was found in 35/83 (42%), hypotonia-related diagnoses in 31/83 (37%), and craniofacial abnormalities in 34/83 (41%). Resolution was observed in 61/83 (74%), either clinically or by polysomnogram, during follow up. On χ2 analysis, surgical intervention was not associated with likelihood of resolution (73% versus 74% in those without surgical intervention, p = 0.98). Patients with airway abnormalities on flexible or rigid evaluation were less likely to have OSA resolution than those without (63% versus 100%, p = 0.010), as were patients with hypotonia-related diagnoses (58% versus 83%, p = 0.014). In patients with laryngomalacia, there was no association of supraglottoplasty with increased resolution (88% with supraglottoplasty versus 80% without, p = 1.00). CONCLUSIONS: We identified a group of infants with OSA with diverse comorbidities. There was a high rate of resolution. This data can assist with treatment planning and family counselling for infants with OSA. A prospective clinical trial is needed to better assess consequences of OSA in this age.
