不同方法清洗内镜的消毒效果及其监测分析

Different Cleansing Methods for Endoscopes Disinfection:A Comparative Study and Surveillance Result Analysis

目的对部分科室内镜清洗消毒效果进行监测,为推广高效清洗消毒方法提供科学依据。方法2005年6月至2006年8月对我院8个科室的内镜分别随机进行3次共161份标本进行细菌学检测。结果本次抽查检测内镜共计161份标本,检出阳性标本32份,阳性率为19.9%。其中,无酶清洗消毒标本84份,监测阳性22份,阳性率为26.2%;含酶清洗消毒标本77份,监测阳性10份,阳性率为13%。含酶清洗消毒与无酶清洗消毒比较,细菌阳性检出率差异有统计学意义(P<0.05)。结论含酶清洗消毒优于无酶清洗消毒,值得临床上进一步推广。

Objective To analyze the effects of different cleansing methods for endoscope disinfection and establish an optimal procedure for that purpose. Methods Bacterial tests were performed with 161 samples collected from 3 inspections of endoscope disinfection. The endoscopes from 8 different departments of our hospital were examined between June 2005 and August 2006. Results Of the 161 samples collected, totally 32 （19.9%） were positive for bacterial tests. In the 32 positive samples, 22 were collected from 84 endoscopes with enzyme-free cleansing （positivie rate of 26.2%）, and 10 were from 77 endoscopes cleansed with enzymatic method （positivie rate of 13%）. There was significant difference in the effects between the two cleansing methods（ P 〈 0.05）. Conclusion Enzymatic cleansing can be more effective than enzyme-free cleansing for endoscope disinfection, and should be used more extensively.
