改良后气道湿化的效果研究

Improved airway humidification effect of the

目的：探讨气管切开患者使用两种气道湿化方法对患者的吸痰量及痰液黏稠度进行比较来研究其疗效。方法：将104例气管切开患者按随机分组法分成对照组和实验组两组，对照组采用传统手工注射器间断滴入法湿化，实验组采用改良后方法即微量注射泵持续泵入法，第4d将吸痰量及痰液黏稠度两项指标进行比较。结果：两项指标实验组较对照组有显著差异P〈0．05。结论：改良后湿化较传统手工滴入法对预防和控制呼吸道感染有明显疗效。

ObjectiveTo explore the curative effect between two therapies with respiratory tract＇s humidilicatlon on patmnts wltn tracneotomy vy making compare with the quantity of sputum aspiration and sputum viscosity. Methods104 patients with tracheotomy is divided into two groups by random grouping. The cases of control group are traditional manual syringe continuous drip as the method of wetting,and the cases for experiment group would be improved method,i, e. trace injection pump continuous pumping method. At the fourth day,the contrast of both factors-the quantity of sputum aspiration and spu- tum viscosity between both group will be made. ResultThe difference in both factors of experiment group in contrast with the one of control group is signifi-cant：P〈0.05. ConclusionHumidification method with improvement has a better effect than the traditional manual injection method on prevention and control of respiratory infections.
