Clinical And Pulmonary Function Characteristics Of Children With Acute Bronchiolitis With Different Imaging Findings

Objective: To explore the clinical and pulmonary function characteristics of children with bronchiolitis with different imaging findings.Method: According to the imaging findings,140 children diagnosed with bronchiolitis were divided into interstitial pneumonia group(70 cases)and bronchial pneumonia group(70 cases).The clinical and tidal breathing lung function characteristics were observed.Exclusion criteria:(1)endogenous inhalation syndrome,such as gastroesophageal reflux,swallowing dysfunction and tracheoesophageal fistula;(2)bronchopulmonary dysplasia;(3)systemic disease;(4)congenital heart disease;(5)malignant tumors;(6)congenital immunodeficiency and/or immune dysfunction.A total of 35 healthy children in the hospital were selected as the normal control group,and the results of tidal pulmonary function test were collected as normal control group.Result: The tidal volume,peak time ratio and peak volume of the interstitial pneumonia group and the bronchial pneumonia group were significantly lower than those of the healthy physical examination group,and the difference was statistically significant(P<0.01).The peak time ratio and peak volume of the bronchial pneumonia group were lower than those in the interstitial pneumonia group,and the difference was statistically significant(P<0.05).The infants in both groups had good treatment and were discharged from the hospital without any death.Regardless of the interstitial pneumonia group or the bronchial pneumonia group(70 cases each),the clinical manifestations were mainly respiratory symptoms such as fever,cough,wheezing,and shortness of breath,and many of them could be heard in the lungs..Peripheral blood WBC increased,lymphocyte increase was more common,and C-reactive protein increased.Other systems outside the respiratory system have fewer symptoms,mostly digestive system manifestations such as vomiting,diarrhea,difficulty feeding,and milder symptoms.The clinical manifestations of children with interstitial pneumonia were higher in patients with wheezing and shortness of breath than those in bronchial pneumonia group,and the difference was statistically significant(P<0.05).The clinical manifestations of children with bronchial pneumonia were fever,WBC.The proportion of CRP increased and wet sputum was higher than that of interstitial pneumonia group,and the difference was statistically significant(P<0.05).The remaining clinical manifestations such as cough,dyspnea,and difficulty in feeding did not show significant differences.Conclusion: Children with bronchiolitis who had changes in interstitial pneumonia and bronchopneumonia showed a comparison of tidal breathing lung function and normal physical examination.There were different degrees of small airway obstructive ventilatory dysfunction,and bronchopneumonia changed.The degree of airway obstruction was more severe and the difference was statistically significant.Conventional pulmonary function tests require high compliance and poor compliance,so they are not used as a routine means of detecting lung function in infants and children.Instead,they are tested for tidal breathing and lung function.In recent years,tidal breathing lung function can be used as an objective basis for evaluating the degree of damage to the lung function of infants and young children.The respiratory manifestations were the main clinical manifestations in both groups.The main clinical symptoms were fever,cough,cough,wheezing,rapid breathing,and dyspnea,and more snoring and snoring in the lungs..The clinical manifestations of children with interstitial pneumonia were more prominent with wheezing and shortness of breath.Bronchial pneumonia was more prominent in lungs.
