简要总结
The aim of the study is to assess the effect of adenotonsillectomy on level of asthma control in preschool children with obstructive sleep apnea.
详细描述
Asthma is the most common chronic disease in children ,in children younger than six years it is difficult to diagnose asthma as pulmonary function tests can not be performed reliably before the age six .
Wheezing is one of the main symptoms of asthma. Young children with multiple trigger wheeze as activities ,laughing and crying are more likely to have asthma compared with episodic (viral) wheeze.
The mainstay of asthma control is daily administration of inhaled corticosteroids, long acting beta2 agonists and avoid exposure of asthma triggers as seasonal allergens and environmental pollution particularly tobacco smoke exposure.
Recent studies have found asthma to be associated with overlapping comorbidities including gastroesophageal reflux,obesity and obstructive sleep apnea.This studies have introduced therapeutic strategies aimed at improving asthma control by management of these coexisting conditions.
Pathophysiological feature of childhood obstructive sleep apnea is presence of increased airway inflammation promoting of hypertrophy of upper airway adenotonsillar tissues .

结局指标
主要结局
preschool children who suffer from bronchial asthma will be assessed by questionnaire based history to assess level of asthma control as stated in GINA 2018 before and after adenotonsillectomy.
时间窗: up to 1year
Questionnaire based history will be obtained from the parents of children before adenotonsillectomy to assess level of asthma control in preschool children as stated in Global Initiative for Asthma (GINA 2018); ask parents in the past 4 weeks, has child had A-Day time asthma symptoms for more than a few minutes, more than once a week? B-Any activity limitation due to asthma? (Runs, tires easily, playing?) C-Reliever medication needed more than once a week? D-Any night waking or night coughing due to asthma? The child will be well controlled if none of this question were answered by yes. The child will be partially controlled if 1-2 of this question were answered by yes. The child will be un controlled if 3-4 of these questions were answered by yes. Repeat this questions after adenotonsillectomy to show prognosis of asthma after surgery.
