微量泵持续湿化人工气道的疗效观察与护理

目的 评价微量泵在人工气道中的持续湿化效果.方法 将60例气管切开患者随机分为2组,每组30例,观察组采用微量泵持续湿化气道法,对照组采用传统的气道内定间断湿化法,分析对比2组气道湿化的效果.结果 观察组形成痰痂、发生刺激性咳嗽、气道出血、肺部感染的例数明显低于对照组,差异有统计学意义（P〈0.05）.结论 微量泵持续湿化法效果优于传统的定时间断湿化法.

Observation and nursing of gas micro pump for keeping the artificial respiratory tract moist

Objective To evaluate the effect of gas micro pump tor keeping the artificial respiratory tract moist. Methods 60 patients wire tra eheostomy were randnndy divided into two groups,namely contral group and intervention group, and each group included 30 patients. The contral group was gived timed and discontinuous moist method,while the intervention group used gas micro pmnp to keep the artificial respiratory tract moist. Compare the effect of two methods. Results The amount of sputum scab,irritating cough,airway bleeding and lung infection in the intervention group was lower compared with the contral group（ P〈0.05 ）. Conclusion The effect of gas micro pump for keeping the artificial respiratory tract moist is better than that of traditional timed and discontinuous moist method.
