Clinical Diagnosis and Treatment of 31 Children with Mycoplasma pneumoniae Necrotizing Pneumonia

Objective: in children. Methods: The clinical features, accessory examinations, treatments, and prognoses of 31 children with M. pneumoniae necrotizing pneumonia admitted to our hospital between January 2020 and June 2023 were retrospectively analyzed. Results: /L, and the proportion of neutrophils was (80.83 ± 4.19) %. C-reactive protein peak was (131.68 ± 36.47) mg/L, and D-dimer peak value was (6.79 ± 2.22) mg/L; The course of pulmonary necrosis was (11.61 ± 3.48) days. Bronchoscopy and lavage were performed on 30 patients. Two patients underwent closed thoracic drainage, and one patient underwent pulmonary lobectomy. After comprehensive treatment with macrolide antibiotics and glucocorticoids, the patient's prognosis improved. Conclusion: Mycoplasma pneumoniae necrotizing pneumonia is more common in preschool and school-aged children with a long heat course and hospital stay. When WBC, neutrophil ratio, D-dimer, and C-reactive protein levels increase significantly, combined with pleural effusion, CT examination of the lungs should be performed to identify M. pneumoniae necrotizing pneumonia at an early stage. Despite a long disease course, most patients have a good prognosis after active treatment.
