纤维胃镜消毒前后细菌学调查

为了解纤维胃镜引起交叉感染的情况，对本院消化内科工作后未经消毒及消毒后的胃镜作了细菌学调查。从１１６例使用后胃镜标本中，共分离到１３６株细菌，革兰氏阴性杆菌占１６％，主要是铜绿假单胞菌（６８．６％）；条件致病菌占２２％，有卡它布兰汉氏菌、库尔特氏菌等。检测了新洁尔灭、“８４”消毒液及消洗宝对使用后胃镜的消毒效果，发现前两者差异无显著性意义（Ｐ＞０．０５），消洗宝的消毒效力明显强于前两者（Ｐ＜０．０５）。

Bacteriological Investigation on Used and Disinfected Gastroscope

In order to know cross infection in hospital caused by using gastroscope, we make a bacteriological investigation with used and disinfected gastroscope. 136 strains bacteria were isolated from the samples of used gastroscope, 16% were gram_negative bacillus which mainly was pseudomonas aeruginosa (68.6%), 22% were opportunistic pathogenic bacteria, including M(B), Catarrhalis, C. Kutscheri et al. The disinfecting efficiency of bromogeramine,“84” disinfectant and Xiaoxi bao were studied, the results showed that the first two had not showed any significant difference(P>0.05),the disinfecting power of Xiaoxi bao was higher than that of the first two(P<0.05).
