摘　　要：目的观察小气道功能异常患者支气管激发试验阳性结果,分析并探讨其临床意义。方法196例支气管激发试验受试者按小气道功能异常情况分为A组和B组,比较两组支气管激发试验结果和吸入支气管舒张剂后肺功能改善的差异。结果 39例有小气道功能异常A组患者中,支气管激发试验阳性33例(84. 6%),显著高于小气道功能正常的B组患者(P <0. 01),且A组吸入支气管舒张剂后小气道功能改善明显低于B组(P <0. 05)。结论针对临床疑似哮喘行支气管激发试验,小气道功能异常患者支气管激发试验阳性率明显升高。Objective To investigate the relationship between small airway function and results of bronchial povocation test （BPT）. Methods 196 patients who had performed BPT were divided into two groups according to the damage of small airway function. The results of BPT and the lung function after inhaling bronchodilator were compared between the two groups. Results Out of 39 patients in the group A, 33 cases had positive results of BPT （84.6%）, and it was significantly higher than that in the group B （ P 〈0.01）. Meanwhile, the improvement of small airway function was more pronounced in the the group B than in the group A after inhaling bronchodilator （ P 〈0.01）. Conclusion For those patients suspected with asthma, they may have higher positive rate of BPT when they are complicated with damage of small airway function.
