Obstructive Sleep Apnea (OSA) in Children
Introduction
Obstructive sleep apnea (OSA) is episodes of partial or complete closure of the upper airway that occur during sleep and lead to breathing cessation. Symptoms include snoring and sometimes restless sleep, nocturnal sweating, morning headache, and problems concentrating. Complications of OSA may include learning or behavioral disturbances, growth disturbance, cor pulmonale, and pulmonary hypertension. Diagnosis is by polysomnography. Treatment is usually adenotonsillectomy. (See also Obstructive Sleep Apnea (OSA) .) The prevalence of obstructive sleep apnea in children is about 2%. The condition is underdiagnosed and can lead to serious sequelae.
