Abstract:[Abstract]Objective To explore the application effect of fiberoptic bronchoscope in children 0-6 years old with plastic bronchitis.Methods The clinical data of 120 pediatric children with plastic bronchitis treated in our hospital from January 2018 to July 2019 were retrospectively analyzed.They were divided into the control group(n=60)and the observation group(n=60)according to different treatment methods.In the control group,pulmonary computed tomography and histopathological sectionon foreign matter in the bronchial cavity and conservative treatment were used.In the observation group,fiberoptic bronchoscopy was ued for diagnosis and treatment.The oxygenation index after treatmentand treatment effect of the two groups were compared.Results The oxygenation index of the observation group was(456.93±19.98)mmHg after treatment,which was higher than that of the control group of(322.59±25.67)mmHg,and the difference was statistically significant(P<0.05).The treatment effect of the observation group was better than that of the control group,with a statistical difference(P<0.05).Conclusion The application of fiberoptic bronchoscope in the clinical treatment of 0-6 years old children with plastic bronchitis improves the oxygenation index and the treatment effect is significant,which deserves widespread clinical promotion.
