纤维内镜的临床应用已在世界上许多国家与地区普及,但对其消毒方法尚不够规范,现就我们的实际工作谈谈对内镜消毒的体会。内镜操作时,感染途径有:1.操作时的自体接种;2.使用巳污染的内镜;3.操作过程中病人之间的传播。最常见的菌丛是来自口咽部的污染菌丛,如溶血性链球菌、金黄色葡萄球菌。而有可能造成严重感染的最常见的的内镜污染菌是绿脓杆菌。其他感染菌尚有沙门氏菌、胃幽门螺杆菌、乙型肝炎病毒、人类免疫缺损病毒等。在医院中,有时也采用消毒的方法来灭菌。例如,一些含有戊二醛的杀菌剂在延长接触时间(长达10小时)时,也有灭菌效用。但是,即使是全防水型的内窥镜,也不能经受多次长时间的浸泡。大部分厂家 Clinical application of fiber endoscopy in many countries and regions in the world, but the sterilization method is not yet standardized enough, and now on our practical work to talk about endoscopic disinfection experience. Endoscopic operation, the route of infection are: 1. The operation of self-vaccination; 2. The use of contaminated endoscopy; 3. During the operation of the spread between patients. The most common bacterial flora is from the oropharyngeal flora, such as hemolytic streptococcus, Staphylococcus aureus. The most common endoscopic contamination that may cause serious infections is Pseudomonas aeruginosa. Other infections are Salmonella, Helicobacter pylori, hepatitis B virus, human immunodeficiency virus and the like. In hospitals, disinfection is sometimes used to sterilize. For example, some glutaraldehyde-containing bactericides also have a sterilizing effect when extended contact times (up to 10 hours). However, even full waterproof endoscopes can not withstand so many prolonged soaking. Most manufacturers
