微量泵连接雾化罐气道湿化的效果

MICRO PUMP CONNECTED TO ATOMIZATION TANK FOR AIRWAY HUMIDIFICATION

目的观察微量泵连接雾化罐持续雾化湿化的效果。方法气管切开或气管插管病人65例,随机分为观察组33例和对照组32例,对照组采用微量泵气道内持续滴注湿化,观察组采用微量泵连接雾化罐持续雾化湿化,观察两组湿化效果及并发症发生情况。结果观察组气道湿化效果明显优于对照组,差异有显著性（u=1.804,P〈0.05）。观察组痰鸣音消失率显著高于对照组,痰痂形成率、刺激性干咳率以及肺部感染率均显著低于对照组,差异有显著性（χ^2=4.58～8.72,P〈0.05）。结论微量泵连接雾化罐持续雾化湿化法用于人工气道湿化效果明显优于传统微量泵气道滴注湿化法。

Objective To observe the effectiveness of using micro pump connected with atomization tank for continued atomization and humidification. Methods Sixty-five patients who underwent tracheotomy or endotracheal intubation were randomized to observation group（n=33）and control group（n=32）.Patients in the control group received micro pump continuous infusion to keep humidification,and those in the observation group were atomized and humidified applying micro pump connected to a atomization tank.The effectiveness of humidification and complications were observed in the two groups. Results The effect of airway humidification in the observation group was much better than that in the control（u=1.804,P〈0.05）.The disappearance rate of wheezy phlegm was much higher than that in the control,and the rates of sputum formation,irritating cough and lung infection were much lower than that in the the control group（χ^2=4.58-8.72,P〈0.05）. Conclusion Using micro pump connected to atomization tank for continuous atomization and humidification for artificial airway is obviously better than traditional micro pump airway instilled humidification method.
