目的研究肺功能检查在小儿哮喘和咳嗽变异性哮喘中的临床应用效果，为临床提供依据。方法选取2013年1月～2015年12月医院诊治的小儿哮喘和咳嗽变异性哮喘患儿90例，设为观察组；选取同期入院的健康体检儿童90例，将其设为对照组。入院后采用肺功能检测仪测定两组小儿第一秒用力呼气量（FEV1）、用力肺活量（FVC）、FEV1占FVC比值（FEV1/FVC）、最高呼气流速（PEF）、残气量（RV）及残气量/肺总量（RV/TLC）指标。结果观察组肺功能检查中FEV1、FVC、FEV1/FVC及PEF指标显著低于对照组（P＜0.05）；观察组肺功能检查中RV及RV/TLC显著高于对照组（P＜0.05）；典型哮喘患儿中肺功能检查确诊率为93.3%，显著高于常规检查的80.0%（P＜0.05）；咳嗽变异性哮喘患儿肺功能检查确诊率为91.1%，显著高于常规检查的60.0%（P＜0.05）。结论与常规检查相比，小儿哮喘和咳嗽变异性哮喘患儿采用肺功能检查效果理想，能了解患儿肺功能变化情况，提高患儿临床确诊率，为临床治疗提供依据。

[Abstract]Objective To explore the clinical application effect of pulmonary function test in infantile asthma and cough variant asthma.Methods 90 patients with infantile asthma and cough variant asthma treated in our hospitals from January 2013 to December 2015 were selected as the observation group.And another 90 healthy children were selected as the control group.Indicators including FEV1，FVC，FEV1/FVC，PEF，RV，and RV/TLC were detected in both groups by lung function detector.Results The values of FEV1，FVC，FEV1/FVC，and PEF were significantly lower in the observation group than those in the control group（P＜0.05）.The values of RV and RV/TLC were significantly higher in the observation group than those in the control group（P＜0.05）.The confirmed diagnosis rate was 93.3%by pulmonary function test in patients with typical asthma，which was significantly higher than the 80.0%by conventional test（P＜0.05）.The confirmed diagnosis rate was 91.1%by pulmonary function test in patients with cough variant asthma，which was significantly higher than the 60.0%by conventional test（P＜0.05）.Conclusion Compared with conventional test，the effect of pulmonary function test is favorable in infantile asthma and cough variant asthma，which can reveal the functional changes of lungs，improve conformed diagnosis rate，and provide basis for clinical therapy.

哮喘是临床上常见的疾病，该疾病在儿科门诊中比较普遍，是主要表现为反复发作咳嗽、呼吸困难等为主要症状的呼吸道疾病。而咳嗽变异性哮喘则是以慢性咳嗽为唯一特征的特殊类型哮喘［1］。……
