氧气湿化装置细菌污染状况分析

目的氧气湿化装置在使用过程中易污染且不易察觉,了解分析临床氧气湿化装置的污染状况,为临床合理使用提供依据。方法将临床使用中的氧气湿化装置进行细菌检测,并进行对比分析。结果复用氧气湿化装置使用前未检出细菌,使用24 h细菌检出率56.7%,48 h细菌检出率100%。使用至24 h、48 h、72 h及7 d时,湿化液中平均细菌量分别为1.25 cfu/ml、32.3 cfu/ml、150.5 cfu/ml及4612.9 cfu/ml;一次性使用的氧气湿化装置连续72 h未检出细菌,使用至7 d、14 d细菌检出率分别为3.0%及13.3%。结论复用氧气湿化装置的污染程度与其消毒水平、保存方式、使用时间、操作方法及湿化液的种类有关;一次性氧气湿化装置优于复用氧气湿化装置。

Bacterial contamination of oxygen humidification devices

Objective Oxygen humidification derices in the course of many links and less easy to detect pollution,understand and analyze the bacterial contamination of oxygen humidification devices for clinical use Methods The clinical devices of oxygen in the wet were detected for bacterial contamination in groups and compared.Results For the reusable devices,the detection rates of bacteria were 0% before use,56.7% at 24 h and 100% at 48 h,respectively;the average bacterial contents of the wetting fluid at 24 h,48 h,7...
