DSG一次性吸氧管在基层医院心内科的应用

目的]探讨DSG一次性吸氧管在基层医院心内科应用的可行性，为临床选择合适的氧疗方式提供依据。方法]将符合研究条件的100例在基层医院心内科住院且需要持续吸氧7d以上的病人，随机分观察组和对照组，观察组使用DSG一次性吸氧管吸氧，对照组使用常规湿化瓶吸氧，比较两组氧气湿化瓶细菌污染情况、病人满意度、直接护理时数。结果]观察组氧气湿化瓶染菌量少于对照组（P〈0．01），吸氧噪声少于对照组（P〈0．05），除氧气异味项外其他咽喉舒适度均明显高于对照组（P〈0．05或P〈0．01），对照组每天更换湿化瓶、湿化液和处理污染湿化瓶耗时25．23min±1．56min，观察组不需要更换湿化瓶和湿化液，节省了执行氧疗的时间。结论]DSG一次性吸氧管在基层医院心内科使用，有利于降低湿化瓶细菌污染情况，减少工作量、吸氧噪声，提高病人的满意度。

Application of DSG disposable oxygen tube in department of cardiology in primary hospitals

Objective：To probe into application feasibility of DSG disposable oxygen tube in department of cardiology in primary hospitals, so as to provide evidences for clinically choosing the suitable way of oxygen therapy. Methods：A total of 100 cases of patients were selected who be eligible for the study and hospitalized in department of cardiology in primary hospi- tals and need continuous oxygen for 7 d, and they were randomly divided into observation group and control group, the patients in observation group received oxygen inhalation with DSG disposable oxygen tube, the patients in control group used conventional wet bottle of oxygen, oxygen humidifier bottles were compared on bacterial contamination, and patients＇ satisfaction and the number of direct care time. Results.oxygen humidifier bottle contamination in observation group was less than that in control group（P〈0.01）, oxygen noise was less than that in control group（P〈0.05） ,throat comfort was significantly higher （P〈0. 05 or P〈0.01）, Replace the humidifier bottles once a day in control group, wet fluid handling contaminated wet bottle and took 25.23 min±1. 56 min in control group Patients in observation group didn＇t need to replace wet bottle and liquid oxygen,and it saved execution time. Conclusion.DSG disposable oxygen tube with wet bottle in department of cardiology in primary hospitals helps to reduce bacterial contamination, reduce workload, oxygen noise and improve patient satisfaction.
