Abstract

Background. To analyze the clinical features of children with plastic bronchitis (PB) and identify the risk factors of multiple flexible fiberoptic bronchoscopy (FOB) therapy. Methods. Retrospective analysis was performed on 269 PB children from 2016 to 2019, 144 cases were in single FOB group, 125 cases were in the multiple FOB group. The clinical manifestations, laboratory datas, imaging findings and management were investigated. The different features were compared between the single FOB group and multiple FOB group. Results. A total of 269 PB children were collected with a mean age of 6.7 ± 2.8 years. 257 (95.5%) cases were diagnosed as Mycoplasma pneumonia (MP) infection. The mean duration of fever was 10.6 ± 3.7 days. All the patients presented with fever, and 62 (23.0%) suffered from hypoxemia, 144 (53.5%) had extrapulmonary complications. Higher levels of ESR, CRP, PCT, IL-6, LA, LDH, FER and D-dimer were observed. The proportion of pulmonary consolidation, segmental or lobar atelectasis, pleural effusion and pleural thickening were 97.4%, 46.5%, 47.9% and 63.2%, respectively. Furthermore, multivariate logistic regression analysis showed that N% >75.5%, LDH >598.5U/L, and D-dimmer>0.45mg/L were independent isk factors for multiple FOB therapy. Conclusions. MP is a significant pathogen of PB in children. Patients with PB are more likely to suffer from persistent fever, excessive inflammation and severe radiological findings. N% >75.5%, LDH >598.5U/L and D-dimmer > 0.45mg/L may be predictors of multiple FOB treatment.
