Abstract:
Objective To evaluate the characters of respiratory function in children with chronic cough and explore the correlative association between cough variant asthma(CVA) and etiology of chronic cough.Methods One hundred and forty patients with chronic cough were divided into 2 groups based on peak expiratory flow(PEF) or forced expiratory volume in one second(FEV1).Ninty-three cases were done exercise test and 47 cases were done bronchoditor rest.The parameters included forced vital capacity(FVC),FEV1,PEF,forced expiratory flow at 50% and 75%(FEF50,FEF75).Results The measurement 35 cases with positive bronchoditor rest,and 30 cases with positive exercise test were found.The PEF and FEV1 variation rate were(18.30?10.50)%,(18.78?9.44)% in exercise test groups,and(30.36?27.27)%,(36.13?26.83)% in bronchoditor rest groups,respectively.Conclusions FEV1,PEF may be used as markers for the reversibility of airway obstructe in children with CVA.There is significant correlation between PEF and FEV1.Respiratory function mensurate may reflect the change and degree of inflammation in the airway of children with chronic cough.
