Abstract:
Objective To evaluate the effect of nebulized bronchodilator on the change of tidal breathing in infants with asthma.This may provide some objective evidence for clinical diagnosis.Methods One hundred and five infants with asthma and 26 cases with pneumonia were involved for the study.Tidal breathing flow-volume was obtained before and 10-15 minutes after nebulized bronchodilator was given.Accor-ding to the basic lung function results,59 cases as a mild group [the ratio of time taken to reach peak expiratory flow to total expiratory time(TPTEF/Te) ≥15%],and 46 cases of the infant asthma as a severe group(TPTEF/Te0.05).Moreover,in severe group,expect for RR and expiratory time(Te),the other indices significantly increased after administration of nebulized bronchodilator(P
