本文探讨雾化吸入溴化异丙托品对慢阻肺患者肺功能的影响，以验证其支气管扩张作用。随机分为两组，治疗组吸入溴化异丙托品，对照组吸入生理盐水。结果显示：治疗组不论雾化吸入前后自身对照还是与对照组比较，吸入嗅化异丙托品后RVC、FEV1均有明显增加（P＜0．05），而对照组雾化吸入前后各肺功能指标均无明显改变（P＞0．05）。以上结果表明，雾化吸入溴化异丙托品可改善患者的肺功能，且能使气道持久扩张，爱喘乐是一种有效、安全的支气管扩张剂。 This article discusses the impact of inhaled inhalation of ipratropium bromide on lung function in COPD patients to verify its bronchodilator effect. Randomly divided into two groups, the treatment group inhaled ipratropium bromide, the control group inhaled saline. The results showed that RVC and FEV1 in both groups were significantly increased (P <0.05) after inhalation of ipratropium compared with self-control or control group before and after inhalation No significant changes in functional indicators (P> 0.05). The above results show that inhaled inhalation of ipratropium bromide can improve lung function in patients, and can make the airway lasting expansion, love asthma is an effective and safe bronchodilator.
