Objective To investigate the clinical characteristics and risk factors of plastic bronchitis(PB)occurrence in children patients with refractory Mycoplasma pneumoniae pneumonia(RMPP).Methods A retrospective analysis was performed on the clinical data of 399 children patients with RMPP treated by fiberoptic bronchoscopy hospitalized in this hospital from January 2017 to December 2019.The pa-tients were divided into the PB group(n=142)and non-PB group(n=257)according to whether or not find-ing PB under fiberoptic bronchoscopy.The differences in clinical characteristics,laboratory detection indicators and imageological manifestations were compared between the two groups.The risk factors of PB occurrence in children RMPP were analyzed.Results Compared with the non-PB group,the incidence rates of hypoxemia and extrapul-monary complications,and the highest body temperature in the PB group were higher,number of fever days and hospitalization days was longer,the proportions of hormone and intravenous injection of immunoglobulin were higher,the levels of NEUT,CRP,IL-6,AST,ALT LDH CK and D-Dimer and incidence rates of pulmo-nary atelectasis and pleural effusion were higher,the levels of PLT and lymphocytes were lower,and the differences were statistically significant(P＜0.05).The receiver operating characteristic(ROC)curve analy-sis results showed that the highest body temperature,NEUT,PCT,IL-6,AST and LDH could serve as the predictive indicators for PB occurrence in RMPP(P＜0.05).The multivariate logistic regression analysis re-sults showed that the highest body temperature＞39.8 ℃,NEUT＞72.9％,IL-6＞26.65 pg/mL,AST＞49.5 U/L and pulmonary atelectasis were the risk factors of PB occurrence in RMPP.Conclusion Should pay at-tention to the risk factors of PB occurrence in children patients with RMPP and take necessary preventive measures to improve their prognosis.
