Abstract: Objective To evaluate the diagnostic values of abnormal features of lung ultrasonography in childrens pneumonia. Methods The examination results of lung ultrasonography in 91 patients were analyzed retrospectively. The results of ultrasonography diagnosis and clinical diagnosis of childrens pneumonia were compared, and the diagnostic efficiency was calculated. The binary Logistic analysis and the receiver operating characteristic(ROC)curve were used to investigate the diagnostic values of these features. Results There were 56 cases with pneumonia and 35 cases without pneumonia. The main characteristics of childrens pneumonia were B line, A line abnormalities, pleural line abnormalities, lung sliding sign abnormalities, lung consolidation and pleural effusion. Lung consolidation was most correlated with pneumonia(P<0.001). The area under the ROC curve(AUC)of lung consolidation was 0.845(P<0.001). The sensitivity, specificity and accuracy of lung consolidation were 80.4%, 88.6%, and 83.5%, respectively. Conclusion Among all the abnormal features, including B line, A line abnormalities, pleural line abnormalities, lung sliding sign abnormalities, lung consolidation and pleural effusion, of lung ultrasonography in childrens pneumonia, lung consolidation is the most valuable feature with highest specificity and accuracy.
