Diagnostic and management effect of bronchoscopy on mycoplasma pneumonia with pulmonary atelectasis in children / 中国小儿急救医学

ABSTRACT

Objective To explore the clinical characteristics of mycoplasma pneumonia with pulmonary atelectasis and lavage interventional effect through fiberoptic bronchoscopy in children.Methods During Jun 2012 to Apr 2013,fifty-three children diagnosed of mycoplasma pneumonia with pulmonary atelectasis who received fiberoptic bronchoscopy were enrolled as the experimental group.Thirty-five children diagnosed of mycoplasma pneumonia without pulmonary atelectasis were chosen as control group.According to the lavage interventional time of fiberoptic bronchoscopy,we divided the patients in the experimental group into two groups,the early group and late group.Clinical data and laboratory finds were collected and analyzed.Results The duration of fever,hospital stay and C-reactive protein (CRP) of the experimental group were significantly higher than those of the control group (P ＜ 0.05).The location of pulmonary atelectasis in the experimental group were usually in the right middle lobe (18 cases,33.9％).Under fiberoptic bronchoscope,all patients had obviously bronchial mucosa congestive edema.Some of them had follicular hyperplasia (9 cases,17.0％),mucosal erosion (3 cases,5.7％),mucus plug formation (7 cases,13.2％) and poor ventilation of segmental bronchi (4 cases,7.5 ％).Neutrophils (43 cases,81.1％) increased and phagocytic cells (31 cases,58.5％) dereased obviously in bronchoalevolar lavage fluid.After treatment in the experimental group,52 children (98.1％) got complete recruitment of atelectasis.The average duration of fever and hospital stay of the early group were significantly shoter than those of late group (P ＜ 0.05).Conclusion Children diagnosed of mycoplasma pneumonia with pulmonary atelectasis had longer fever duration and higher CRP level.Bronchoscopic interventional therapy promoted the recovery of pulmonary atelectasis.Using bronchoscop early in shorten the duration of fever and hospitalization in children diagnosed of mycoplasm pneumonia with pulmonary atelectasis.
