支气管哮喘可在老年发病。由于增龄本身即引起肺功能减退,老年人的常见呼吸道症状如咳嗽、咳痰和呼吸困难等又多被误认为是慢性支气管炎、职业性肺病以及失代偿性心衰的表现,所以老年发病的支气管哮喘极易被误诊或漏诊。作者随机选择199名老年人,平均年龄78.3岁(55—97岁),男83,女116。其中70岁以上者180名(95.5％)。在给药前及吸入200μg 舒喘灵5分钟后测定 FEV_1、FVC 和 PEFR。结果表明:吸入舒喘灵后,82名受试者(41.2％)PEFR 占预计值的百分数较用药前增加≥15％。用药后 FEV_1和 FVC 占预计值的百分数增加≥15％者,分别为99例(49.7％)和91例(45.7％),但重复性不及PEFR。根据给药后 PEFR 占预计值的百分数是否增加
Bronchial asthma can be senile. As aging itself causes lung dysfunction, common respiratory symptoms such as cough, sputum and dyspnea in elderly people are often mistakenly identified as chronic bronchitis, occupational lung disease and decompensated heart failure, so elderly The incidence of bronchial asthma can easily be misdiagnosed or missed diagnosis. The authors randomly selected 199 older adults, with an average age of 78.3 years (55-97 years), 83 men and 116 women. Among them, 180 were over 70 (95.5%). FEV 1, FVC and PEFR were measured before dosing and after inhaling 200 μg salbutamol for 5 minutes. The results showed that, after inhaled salbutamol, 82 subjects (41.2%) PEFR percentage of the predicted value increased more than 15% before treatment. The percent increase in FEV_1 and FVC predicted to be ≥15% after treatment was 99 (49.7%) and 91 (45.7%), respectively, with less reproducibility than PEFR. According to PEFR after administration accounted for the expected percentage of the increase
