Importance of lung function examination in the diagnosis of elderly patients with bronchial asthma

目的探讨肺功能检查在老年支气管哮喘诊断中的意义。方法调查我院286例老年支气管哮喘确诊患者,其中观察组144例,经肺功能检查确诊,对照组142例患者经身体特征确诊,分析两组患者的误诊率。结果经跟踪调查发现观察组中有10例患者不是支气管哮喘,误诊率6.9%;而在对照组中有21例患者不是支气管哮喘,误诊率为14.7%。两者差异有统计学意义(P<0.05)。结论肺功能检查诊断支气管哮喘的误诊率低,对临床指导治疗支气管哮喘有着十分重要的意义。

Objective To discuss the importance of lung function examination in the diagnosis of elderly patients with bronchial asthma. Methods 286 elderly patients with bronchial asthma were divided into 144 cases of the observation group diagnosed by lung function examination and 142 cases of the control group diagnosed by body characteristics. The misdiagnose rate was analyzed between the two groups. Results There were 10 cases who were not bronchial asthma in the observed group, and the misdiagnosis rate was 6.9%. There were 21 cases who were not bronchial asthma in the control group, and the misdiagnosis rate was 14.7%. The difference of misdiagnosis rate showed statistical significance between the two groups. Conclusion The misdiagnosis rate of lung function examination is low, and it has important significance on the clinical treatment of bronchial asthma.
