Clinical feature,lung imaging and bronchoscope characteristics analysis of infant bronchial foreign body / 国际儿科学杂志

ABSTRACT

Objective To investigate the advantages of pediatric electronic fiber bronchoscope ( FBO) in the infant bronchial foreign body,discuss the clinical features of infant bronchial foreign body,lung imaging characteristics and the kinds of microscopically position,the change of airway mucosa after stimulation by for-eign body under local anesthesia in 30 cases of infant bronchial foreign body. Methods Thirty cases,aged 0 to 3 years,were collected from September to December,2014. All of them were with foreign bodies examined by FBO in pediatric bronchoscopy room in Shengjing Hospital of China Medical University. Results In all infants, 6 cases (20. 0%) without history of inhaled foreign bodies and 24 cases (80. 0%) with a record history of in-haled. In the aspects of signsnormal breath sounds with a history of no choking cough in children were 2 cases (6. 7%) ,wheezing sounds were 3 patients (10. 0%) and weakened side breath sound was 1 case (3. 3%);with a history of choking cough in children,6 cases(20. 0%) with normal breath sounds,12 cases(40. 0%) with wheez-ing,6 cases(20. 0%) with lateral breath sounds less. Lung imaging characteristics was lack of specific perform-anceonly a case of all(n=30)show foreign body directly. Otherwise,other 29 cases had no specificity. Lung em-physema in 13 cases (43. 3%) is the main characteristic,while normal imaging findings in 2 cases (6. 7%). For-eign bodies in 19 cases were in the left lung (63. 4%) and 21 cases(70. 0%) of foreign body stimulated granula-tion inside airway,necrosis sputum bolt in distal obstruction of airway occured in 5 cases (16. 7%). Inhalled time of foreign body in airway was 4. 5 [2. 8,12. 5] day and inhalled time of foreign body in airway correlation coefficient with granulation hyperplasia(r=0. 688,P=0. 000),there was a significant correlation. Main adverse reaction was low oxygen in 6 cases (16. 7%). Conclusion The diagnostic accuracy of FBO under local anesthesia on children is high-er than other methods,and the FBO bronchial foreign bodies under local anesthesia is a safe and effective method.
