摘要
目的保证氧疗效果,解决氧气湿化过程中普遍存在的湿化液污染及湿化产生噪声问题。方法将172例需吸氧的肺癌患者随机分为观察组和对照组各86例,观察组应用自行研制的新型氧气湿化输送系统吸氧,对照组使用传统氧气湿化输送系统吸氧。结果观察组仅1例患者主观感受到湿化噪声,与对照组比较,差异有统计学意义(P<0.01);观察组湿化单元细菌培养阳性率显著低于对照组(P<0.01)。结论新型氧气湿化输送系统应用于临床氧疗,能降低传统氧气湿化液污染导致的医院呼吸道感染的风险,降低噪声,可保证患者休息,且不影响氧疗效果。
Objective To solve the problem of fluid contamination and noise production during oxygen humidification. Methods A total of 172 patients were equally divided into a control group and an observation group. The observation group employed a newly invented device to humidify oxygen before inhalation, while the control group used a traditional method for humidification. Results The percentage of patients who complained of noises during oxygen inhalation in both groups had significant difference （P〈0. 01）. Rate of positive findings of bacteria culture for humidifying containers was lower in the observation group than that in the control group（P〈0.01）. Conclusion The new humidifying system can reduce the risk of nosocomial infection during humidification. Meantime it can improve sleep quality of patients and help them inhale oxygen completely.
