The value of lung ultrasound in assessing the degree of lesions in children with mycoplasma pneumoniae pneumonia

Objective: To investigate the value of lung ultrasound (LUS) in assessing the degree of lesions in children with mycoplasma pneumoniae pneumonia (MPP). Methods: The clinical data of 100 children with pediatric MPP admitted to Jincheng General Hospital were retrospectively analyzed. Based on the standard of refractory MPP, the enrolled MPP-children were divided into refractory MPP group (n=25) and general MPP group (n=75). The general data were collected and compared between the two groups. The length of parenchymal lung lesions, the area in parenchymal lung lesions, and APACHE II scores were compared between the two groups. Logistic analysis was used to explore the risk factors that influence the extent of lesions in children with MPP. The receiver operating characteristic (ROC) curve was used to evaluate the ability of candidate indicators to predict the extent of lesions in children with MPP. Results: Logistic regression equation analysis revealed that the length and area of parenchymal lung lesions were the factors influencing the extent of lesions in children with MPP (P<0.05). ROC curve showed that the AUC value of length of parenchymal lesions was 0.667, and the best sensitivity and specificity were 78.56% and 69.14%, respectively. The AUC value of area of parenchymal lesions was 0.582, and the best sensitivity and specificity were 58.19% and 81.04%, respectively. Conclusion: Lung ultrasound measurement of length and area of parenchymal lung lesions can be used to assess the extent of lesion in children with MPP and provide a basis for clinical treatment planning.
