The Diagnostic Value of Lung Ultrasonography in Children Community-Acquired Pneumonia

Abstract

To explore the diagnostic value of lung ultrasonography in children community-acquired pneumonia is the objective of the study. A total of 126 children who were diagnosed with community-acquired pneumonia and underwent lung ultrasonography examination during the course of the disease were selected. All patients underwent lung ultrasonography and chest X-ray examination within 24 h of admission. The clinical characteristics of lung ultrasonography examination of community-acquired pneumonia were analyzed and the sensitivity, specificity, correct index and diagnostic coincidence rate of lung consolidation with lung ultrasonography and chest X-ray were compared. The lung ultrasonography imaging features of severe community-acquired pneumonia in children are the disappearance of A-line, increase of B-line, waterfall sign, lung consolidation, bronchial inflation sign, pleural effusion, etc. 53 cases of patients chest computed tomography results were used as the gold standard. The sensitivity, correct index and diagnostic coincidence rate of lung ultrasonography in the diagnosis of lung consolidation were all higher than those of X-ray diagnosis and the differences were statistically significant (p<0.05). Lung ultrasonography determined abnormal changes in the lungs of 124 children and chest X-ray determined abnormal changes in the lungs of 122 children. The chest X-rays of 2 children showed normal, while the lung ultrasonography showed a large number of B-line and lung consolidation in both lungs. A total of 17 cases of pleural effusion were determined by lung ultrasonography and 1 case of pleural effusion was determined by chest X-ray. The difference between the two groups was statistically significant (p<0.05). Lung ultrasonography in children community-acquired pneumonia is superior to chest X-ray in lung consolidation and pleural effusion and can be used for diagnosis of children community-acquired pneumonia.
