Efficacy study of bronchoscopy lavage treatment for refractory Mycoplasma pneumoniae pneumonia

??Objective To analyse the treatment effects of bronchoscopy lavage treatment for RMPP??and to study the proper time to do the operation. Methods A total of 76 cases??from June to December 2013??were enrolled in the retrospective study. According to the the course of the disease??there were divided into three groups??≤2 weeks????2??3 weeks and ??3 weeks. The febrile period??duration of hospital stay??WBC??N%??L%??CRP??the chest radiography and the bronchoscopic findings were compared with each other. Results The febrile period??≤2 weeks group it was 13.9±3.8?? in ??2??3 weeks group??14.1±5.0?? in ??3 weeks group??14.1±5.0?? they all had significant difference between each other. The chest radiographic changes were divided into complete absorption??partial absorption and no change. Compare the chest radiography at the 7th day after operation?? the ratio was 14.3%??5.4% and 0??85.7%??75.8% and 76.0%??0??18.9% and 24.0%. At one month??the ratio was 41.4%??26.3% and 11.3%??42.4%??65.7% and 75.1%??0??7.9% and 13.6%. According to the bronchoscopic findings we analysed??the airway mucosal or bronchial wall’s lesions in RMPP mainly were white mucosa covered??mucosal erosions and roughness. Lumen stenosis??dilator??obliteration and mucosa plug were seen more in the third group. Conclusion In the treatment of RMPP children??earlier bronchoscopy therapy can help shorten the fever course and promote chest radiography improvement. The mycoplasma infection of long time could cause lumen stenosis??dilator??obliteration and mucosa plug.
