潮气呼吸肺功能测定在5岁以下支气管哮喘儿童中的应用
Study on lung function test via tidal breathing in children under age of 5 years with bronchical asthma
摘要
Abstract
Objective To investigate the changes in large and small airway function of asthmatic children under age of 5 years by comparison of the lung function index of tidal breathing changes pre and post regular treatment. Methods Twenty asthmatic children under age of 5 years who were measured with tidal flow volume curve function test pre and post treatment, with 20 healthy children were enrolled as control. Results ( 1 )Comparison to healthy children, the index of large airway function ineluding VT/kg,TPTEF/TE, VPEF/VE,Ti/Te,TEF25％ ,TEF50％ in asthmatic children were significantly improved in acute stage, while the indexes were still lower than those in healthy children, Rr was higher than healthy children ( P ＜ 0.05 ). There was no statistical significance in other indexes( P ＞ 0. 05 ). ( 2 ) The indexes of TPTEF/TE, VPEF/VE, TEF50％ , and TEF25％ in asthmatic children were improved in recovery stage, while still lower than those in healthy children ( P ＜0. 05 ). There was no statistical significance in other indexes( P ＞0.05 ). ( 3 )Comparison to acute stage, the indexes of VT/kg, Ti/Te, TPTEF/TE, VPEF/VE in asthmatic children were improved( P ＜0. 05 ), while no statistical difference in other indexes( P ＞ 0.05 ). Conclusion It demonstrated the value of lung function test via tidal breathing in evaluating airway function of asthmatic children under age of 5 years old.关键词
