Application of fiberoptic bronchoscopy in the diagnosis and treatment of chronic cough in children / 中国小儿急救医学

ABSTRACT

Objective To explore the application value of fiberoptic bronchoscopy in the diagnosis and treatment of chronic cough in children. Methods A total of 113 children with chronic cough were enrolled in our hospital from January 2014 to December 2016. All the cases underwent fiberoptic bronchoscopy,the endoscopic manifestations and clinical symptoms were analyzed,and the pathogens in bronchoalveolar lavage fluid were detected. Results In the 113 children with chronic cough,64 cases (56. 6％) were boys and 49 cases (43. 4％) were girls,with 85 cases (75. 2％) under 5 years old. After fiberoptic bronchoscopy,30 cases (26. 5％) were diagnosed with bronchial foreign body,20 cases (17. 7％) were post-infection cough, 19 cases (16. 8％) with cough variant asthma,14 cases (12. 4％) with upper airway cough syndrome,14 cases ( 12. 4％) had airway abnormality, 9 cases ( 7. 9％) had protracted bacterial bronchitis, 4 cases (3. 6％) had bronchiolitis obliterans,and 3 cases (2. 7％) had bronchial tuberculosis. The most common pathogen was Streptococcus pneumonia in bronchoalveolar lavage fluid. The main adverse reactions in the operations was hypoxemia caused by airway obstruction. Conclusion Fiberoptic bronchoscopy is a very safe and reliable operation in the diagnosis and treatment of respiratory diseases in pediatrics, and plays an important role in the diagnosis of congenital developmental airway diseases,the detection of pathogens and the treatment of bronchial foreign bodies. For the chronic cough children who had repeated visits and poor treatment should accept fiberoptic bronchoscopy examination.
