医源性感染是存在于医疗卫生机构中的一种疾病传播方式,经血液传播是医源性感染的重要途径,极微量的含病毒血液(0.0004ml)即具有传染性[1]。活检钳在夹取组织时必然会穿破黏膜,接触血液、体液、组织、瘤体,破坏黏膜屏障,而未达到灭菌要求的活检钳则会造成院内交叉感染,而清洗是保证灭菌质量的关键。2011年11月~2012年3月,我院把
Iatrogenic infection is a mode of transmission of the disease that exists in medical and health institutions. Transmission through blood is an important way of iatrogenic infection. A very small amount of infectious blood (0.0004 ml) is contagious [1]. Biopsy forceps will inevitably pierce the mucosa when the tissue is taken and contact the blood, body fluids, tissues and tumor, destroy the mucosal barrier, and the biopsy forceps that do not meet the sterilization requirements will result in cross infection in the hospital, and the cleaning is to ensure the quality of sterilization key. November 2011 ~ March 2012, our hospital put
