[Objective] To explore the common causes of recurrent wheezing in infants and bronchoscopy recurrent wheezing in infants and young children in the diagnosis and treatment of diseases value and safety . [Method] The Children's Hospital of Chongqing Medical University from January 2008 to December 2010 admitted 212 patients aged ≤ 3 years , recurrent wheezing in children ≥ 3 times for the study, a retrospective analysis of the clinical data , imaging studies , bronchoscopy , bronchoalveolar lavage and treatment situation. All the children will be divided according to age group and 1 year old to 3 years old group , and in accordance with the course is divided into lt; 1月, lt; 3月, ≥ 3月three groups , comparative analysis of different age groups , different causes of disease group distribution whether the differences . [Results] 212 cases in 172 cases diagnosed by bronchoscopy ( 81.1% ) . The most common cause tracheobronchomalacia ( 88 cases , 41.5% ) , and the infant group was significantly higher than children , and in the lt; 3月, ≥ 3月proportion in both groups increased . Followed by 30 cases of bronchial asthma , airway stenosis in 27 cases, 26 cases of pneumonia , airway stenosis softening combined 19 cases, 11 cases of abnormal openings , vascular ring six cases , congenital laryngeal cartilage dysplasia two cases , one case of bronchus and right undeveloped one case of lung , pulmonary hemosiderosis disease in 1 case. 177 cases of pathogens in bronchoalveolar lavage fluid culture positive for 99 cases ( 55.9% ) . 15.1% of the children had mild complications , mainly for postoperative fever ( 18 cases ) , intraoperative transient desaturation ( 6 cases ) , with no serious complications. [Conclusion] The results showed that recurrent wheezing in early childhood diseases , in addition to bronchial asthma, tracheobronchomalacia , airway stenosis, congenital airway abnormalities but also for the common cause .
