2%碳酸氢钠对机械通气患者气道湿化效果的研究

Study of Effects of 2% NaHCO_3 on Air Tube Humidification

目的:观察2%碳酸氢钠对机械通气患者气道湿化的效果。方法:将46例患者随机分成观察组和对照组,对照组用传统方法配制的湿化液湿化,观察组用2%的碳酸氢钠溶液进行气道湿化,用药后对两组痰液黏稠度转化时间进行观察。结果:在痰液黏稠度转化时间方面,观察组明显优于对照组(P<0.05)。结论:采用2%碳酸氢钠溶液可有效稀释痰液,且不良反应小,具有推广价值。

Objective： To observe the effects of 2 % NaHCO3 on air tube humidification.Methods： Forty-six patients were randomly divided into observation group and control group.The observation group used 2 % NaHCO3 for air tube humidification,and the control group used traditional method.Then the transformation time of sputum viscosity was analyzed.Results： The transformation time of sputum viscosity in observation group is significantly shorter than that in control group.Conclusion： Two percent NaHCO3 can effectively dilute sputum and has few side effects.
