摘要 目的探讨不同浓度高渗盐水雾化在支气管哮喘患者痰诱导的成功率及安全性的差异。方法对24例哮喘患者及10例健康人员先后间隔72 h以单一浓度法(3%)和梯度浓度法(3%~4%~5%)各进行1次高渗盐水的雾化痰诱导。对两种方法的诱导成功率进行统计,观察诱导期患者的肺通气指标:PEF,心率及血氧饱和度的变化,比较痰液重量、痰细胞总数及鳞状上皮细胞比例等参数。结果单一浓度法及梯度浓度法诱导总成功率分别为88.2%和94.1%;两种方法咳出的痰量、痰细胞总数和鳞状上皮细胞比例无显著差异;单一浓度法的PEF,HR、SpO2在诱导前后均无显著变化,梯度浓度法诱导后患者的PEF,HR及SpO2:均出现显著下降(P〈0.01)。结论单一浓度法和梯度浓度法均为可行及有效的痰诱导方法,但在梯度浓度法雾化过程中更需要注意患者的安全性问题。
