Bronchiolitis obliterans refers to lung bronchiole injury caused by infection or other reasons, coughing and wheezing that last more than 6 weeks, with or without breathing difficulties, exercise intolerance, which seriously affects physical and mental health and life Quality chronic airflow limitation syndrome.Bronchiolitis obliterans is mainly manifested by coughing and wheezing. Generally, there are 2-4 days of low-grade fever, nasal congestion and runny nose, accompanied by symptoms of lower respiratory tract diseases, including cough, shortness of breath, nasal inflammatory and tri-concave signs. You can hear expiratory wheezing during auscultation. A small number of severely ill children can develop heart failure or respiratory failure, or even life-threatening. Although bronchiolitis has a high cure rate, some children die, and it is closely related to repeated wheezing and the development of asthma in the future, even endangering children health. Bronchiolitis is associated with many risk factors, including premature birth, passive smoking, young age, lack of breastfeeding, malnutrition, chronic lung disease, congenital heart disease, atrioventricular block, male, ethnicity, viral infection , Low weight at admission, multiple pregnancy, mother smoking during pregnancy, allergic dermatitis, neonatal mechanical ventilation, mothers with allergies or asthma during pregnancy, season of birth, low socioeconomic status, Down syndrome, environmental pollution , Living environment height>2500 meters above sea level and cesarean section, etc. In order to study the clinical features and imaging of bronchiolitis obliterans, this article investigates the pathological characteristics of 100 patients from the hospital and conducts a follow-up survey of these 100 patients to understand the prognostic treatment of patients during and after treatment. The study found that the prevalence of bronchiolitis obliterans in infants under 1 year old is about 18-32%, the prevalence of children under 2 years old is 9-17%, and the prevalence of infants under 2 years old is about 1-3%. Children with bronchiolitis require hospitalization. Children with bronchiolitis obliterans are prone to have diarrhea during the course of their illness. In addition, myocardial damage and liver damage may also occur, and a small number of patients have heart failure, respiratory failure, and even endanger the life of the child. This shows that bronchiolitis obliterans is extremely harmful to children and needs to be paid attention to by parents and experts, and be prepared in its early and prognostic treatment.
