Abstract：Objective To explore the relationship between the ultrasonographic findings of the lungs in children with severe pneumonia and the clinical treatment effect of the children.Methods 80 children with severe pneumonia admitted to our hospi-tal(severe group)were selected,and another 80 children with common pneumonia treated at the same time(control group)were selected.Both groups of children underwent lung ultrasonography.We compared severe and non-severe cases,observed the dif-ferences in lung ultrasound examination performance of children in the critically ill group before and after treatment,grouped them according to the curative effect,compared the differences in lung ultrasound examination performance between the treat-ment effective group and the treatment ineffective group,and completed the impact on the clinical efficacy of such children by Logistic regression analysis.Results The proportion of children with B lines≥10,pleural effusion,air bronchus sign,pleural abnormality,and pulmonary consolidation in the severe group was significantly higher than that in the control group(P<0.05);after treatment,the children in the severe group had B lines≥10 Lines,pleural effusion,tracheal air sign,pleural abnormality,and pulmonary consolidation were significantly lower than those before treatment(P<0.05);in the effective treatment group,there were more than 10 B lines,pleural effusion,bronchial air sign,and pleural abnormality were significantly lower than the treatment-ineffective group(P<0.05);Logistic regression analysis confirmed that B-line≥10,pleural effusion,tracheal infla-tion,pleural abnormality,and pulmonary consolidation were an independent risk factors for treatment failure in children with se-vere pneumonia(all OR>1,P<0.05).Conclusion Lung ultrasonography can be used in the diagnosis and differentiation of children with severe pneumonia,and the efficacy can be evaluated by the changes of lung ultrasonography during treatment.
