温开水作为吸痰冲洗液的安全性探讨

Probe into the safety of using warm boiled water as sputum suction flush fluid

目的探讨温开水作为吸痰冲洗液的安全性及更换冲洗液时间的合理性。方法将符合研究条件的42例患者床旁分别放置盛有适量温开水的无菌容器以及开启铝盖的玻璃瓶装生理盐水,观察2组冲管液在不同时间的细菌培养阳性率。结果温开水组冲洗液细菌培养阳性率为23.81%,生理盐水组为30.95%,差异无统计学意义(P>0.05);2组冲洗液在放置4h后细菌污染程度均明显加重。结论温开水作为吸痰冲洗液是安全的,且4h更换一次是合理的。

Objective To probe into the safety of using warm boiled water as sputum suction flush fluid and the rationality of the time to replace .flush fluid. Methods The sterile containers filled up with adequate warm boiled water and the aluminum cover opened glass bottles filled up with normal saline were placed by the bed of the 42 patients meeting the research requirements, respectively. To observe the bacteria cultivation results of two groups of flush fluid in different time. Results The bacteria cultivation positive rate of the warm boiled water group was 23.81%, and the normal saline group was 30.95%. This suggested that the two groups have no statistically significant differences（P〉0.05）. After four hours, the bacterial contaminations of both groups were significantly increased. Conclusion Using warm boiled water as sputum suction flush fluid is safe and the flush fluid should be replaced every 4 hours.
