ABSTRACT
Objective To evaluate the diagnostic value of chest X-ray film of pulmonary emphysema (PE)signs for infantile bronchitis.Methods Clinical data of 60 infants with bronchitis (case group)in a hospital between Janu-ary 2010 and December 2014 were analyzed retrospectively,and compared with data of 30 infants with non-respira-tory diseases (control group).Results Of 60 infants with bronchitis in case group,95.00%(57/60)showed mani-festations of PE on X-ray,and 18.33% (11/60)of whom were with mild PE(apical or intercostal pneumocele), 76.67%(46/60)were with typical PE (diaphragm descent);one case (3.33%)in control group showed intercostal pneumocele,the other 29 cases (96.67%)were normal X-ray findings and without signs of PE.The sensitivity, specificity and accuracy of PE signs on chest X-ray film for diagnosing infantile bronchitis were 95.00%,96.67%, and 95.56% respectively.Conclusion Signs of PE on chest X-ray film have important diagnosis value for infantile bronchitis.
