A retrospective analysis was conducted on the clinical data of 100 children with MPP treated at our hospital from April 2022 to April 2024. The patients were divided into an experimental group (50 cases) and a control group (50 cases) based to the treatment method. Both groups received routine treatment, however, the control group was treated with electronic fibrobronchoscope alveolar lavage alone, while the experimental group received electronic fibrobronchoscope alveolar lavage combined with local administration of budesonide. The efficacy of the two treatments was compared. The experimental group showed a significantly higher overall effective rate than the control group (<i>p</i><0.05). After treatment, the time for cough relief, lung rales resolution, fever reduction, and hospital stay were significantly shorter in the experimental group compared to the control group (<i>p</i><0.05). One week after treatment, the levels of tidal volume, vital capacity, and peak expiratory flow in the experimental group were higher than those in the control group (<i>p</i><0.05).
