Quantitative evaluation and significance of ultrasound in bronchoalveolar lavage for lung consolidation in children with severe mycoplasma pneumonia

BACKGROUND: The aim of this study was to evaluate the effect of lung ultrasound on bronchoalveolar lavage in the treatment of mycoplasma pneumonia in children. METHODS: Thirty children with mycoplasma pneumonia who were treated with medication and bronchial lavage were selected. We collected the results of laboratory and imaging examinations after admission, and the changes in lung consolidation area were examined by ultrasound before, immediately upon completion, and at 1, 3, and 7 days after bronchoalveolar lavage. The effective factors affecting bronchial lavage were analyzed through logistic regression. RESULTS: Univariate regression analysis showed significant differences in the lung consolidation area at admission, before, immediately upon completion, and at 1 and 7 days after lavage, as well as in the disease course and atelectasis (or not). Multivariate analysis showed that there were statistical differences in the lung consolidation area at admission, atelectasis (or not), and disease course: lung consolidation area at admission [odds ratio (OR): 2.31512, 95% confidence interval (CI): (0.00182, 0.031775), P=0.029474], atelectasis [OR: 2.695742, 95% CI: (0.079281, 0.597218), P=0.012629], and disease course [OR: −2.43347, 95% CI: (−0.02568, −0.00211), P=0.022773]. CONCLUSIONS: Lung ultrasound can evaluate the effect of bronchial lavage through lung consolidation and atelectasis, which can provide a reference for clinical treatment.
