目的 探讨哮喘患儿运动诱发哮喘的发生率。方法 采用标准的运动激发试验 ,对 36例哮喘患儿进行检测 ,以 36例健康儿童作对照 ,以运动后最大呼气峰流速的改变率 (△PEFR)≥ 15 %为标准。结果 2 2 / 36(6 1 1% )运动诱发哮喘 (EIA)阳性 ,而对照组全部阴性。结论 哮喘患儿运动诱发哮喘发生率为 6 1 1% ,应加强对哮喘患儿运动可诱发哮喘的认识和保护
Objective To investigate the incidence of exercise-induced asthma in children with asthma. Methods Thirty - six children with asthma were tested by standard motor provocation test. Thirty - six healthy children were used as control. The change rate of the maximum expiratory peak flow velocity (△ PEFR) ≥ 15% after exercise was used as the standard. Results 2 2/36 (61.1%) exercise-induced asthma (EIA) positive, while the control group were all negative. Conclusion The incidence of exercise-induced asthma in children with asthma is 61.1%, and awareness and protection of exercise-induced asthma in children with asthma should be strengthened
