无湿化中低流量鼻道管持续吸氧在ICU患者中的应用

目的探讨无湿化中低流量鼻道管吸氧在重症监护室(intensive care unit,ICU)患者中的应用效果。方法将400例在ICU住院,需要持续中低流量吸氧24h以上的患者,随机分为实验组和对照组,每组各200例。实验组患者使用干燥湿化瓶直接吸氧,对照组患者使用湿化瓶吸氧。比较两组患者吸氧24h后呼吸道反应,湿化瓶细菌污染,患者对吸氧噪声反映情况及护士更换湿化瓶所需时间。结果两组患者氧疗后不适症状与各项指标比较,差异无统计学意义(均P0.05);两组患者湿化瓶细菌污染情况、患者感觉噪声、护士更换湿化瓶所需时间比较,均P0.05或P0.01,实验组细菌污染阳性率明显低于对照组,患者感觉吸氧噪声情况明显少于对照组,护士更换湿化瓶时间明显短于对照组。结论中低流量患者采用无湿化吸氧有利于降低湿化瓶细菌污染情况,减少工作量及吸氧噪声,值得临床推广应用。

Application of non-humidified low flow nasal oxygen inhalation in ICU patients

Objective To investigate the application of non-humidified low flow nasal oxygen inhalation in the ICU patients.Methods Four hundred patients hospitalized in ICU and needing continuous low-flow oxygen inhalation for more than 24 h were randomly divided into experiment group and control group equally.The experiment group were managed with dried humidification bottle oxygen inhalation and the control group conventional humidified bottle oxygen inhalation.The two groups were compared in terms of 24 h respiratory reactions,bacterial contamination of the humidified bottle,complaints of patients about oxygen inhalation noises and time for nurses to change the humidified bottles.Results The two groups had no significant difference in adverse symptoms（all P〉 0.05）.The rate of bacterial contamination in the experiment group was significantly lower than the control group（P〈0.05）,the noises were lower and the time for changing the bottle shorter（P〈0.05）.Conclusion Non-humidified low flow nasal oxygen inhalation in ICU patients is good for reducing the rate of bacterial contamination of humidified bottle and lowering workload and oxygen-inhaling noises.
