Clinical Trial Summary

The purpose of the study is to establish the methodology of bronchial dilation test by salbutamol MDI with Spacer in wheezy infants with asthma and to evaluate the effects of atopy on the exacerbation of wheeze in wheezy infants.


Clinical Trial Description

After screening,each participant undergo baseline pulmonary function test(Jaeger Master Screen Baby Body, Germany)and post-bronchodilator measurements that performed 10min after 200ug of salbutamol administered using a metered-dose inhaler and a spacer.
