摘要:

摘要:目的    探讨呼出气一氧化氮(FENO)与儿童哮喘控制测试(C-ACT)、支气管激发试验(BPT)指标的相关性。方法    选取2011年3月至2011年9月于重庆医科大学附属儿童医院哮喘门诊就诊的哮喘患儿48例,年龄5~12岁,根据2009年全球哮喘防治创议(GINA)标准分为控制组17例、部分控制组14例和未控制组17例,分别完成FENO测定、肺功能检查及C-ACT问卷,第1秒用力呼气容积占预计值的百分比(FEV1%)合格的患儿完成支气管激发试验,记录出现FEV1下降超过20%的乙酰甲胆碱浓度(PC20),分析三组间的FENO、C-ACT、FEV1%、BPT结果及其相关性。结果    哮喘儿童FENO几何均数(22.5 ± 2.0) × 10-9 mol/L,未控制组FENO明显高于控制组和部分控制组。三组间的C-ACT、FEV1%、BPT结果差异均有统计学意义。FENO与FEV1%呈弱的负相关,PC20与FEV1%有弱相关,而FENO、C-ACT、PC20三者间均无明显相关性。结论    在哮喘的管理和评估中,FENO需与肺功能、BPT、C-ACT等其他指标联合应用。

Abstract:

Abstract: Objective    To find out the fractional exhaled nitric oxide( FENO) in different control level and the relationship of FENO with childhood asthma control test (C-ACT) and bronchial provocation test(BPT). Methods    Totally 48 asthmatic children who underwent routine checkups since March 2011 through September 2011 were enrolled in the study. The patients completed the detection of FENO, they also underwent pulmonary  function  test(PFT),  bronchial  provocation test (BPT)and C-ACT. Those indexes and relationships were analyzed in different control groups. Results          The geometrical mean FENO of asthmatic children was (22.5 ± 2.0) × 10-9 mol/L. Uncontrolled group had higher FENO than controlled group and partly controlled group, and FENO was  slightly  related to FEV1% Pred,so did PC20,but no relevance had been found between FENO, C-ACT or PC20. Conclusion    FENO can be an useful tool in managing asthma when used together with C-ACT,PFT and BPT.
