目的了解虹口区病原微生物实验室冰箱的使用、污染情况,分析目前在卫生监管中存在的问题,探讨相应的对策。方法采用定量研究方法,对虹口区病原微生物实验室用冰箱的全覆盖检测及相关人员的调查结果进行相关统计分析,分析发现的普遍问题。结果临床实验室使用冰箱尚未引起人们关注,处于监管盲区。生物学检测显示,放置待处理标本,即阳性、阴性标本混放冰箱的细菌菌落总数合格率较低,频繁采用湿式消毒的冰箱真菌合格率较低。结论严密关注冰箱的低温保存能力,规范贮存制度,尽量将待处理标本单格存放,并采用合适的方法进行冰箱消毒,是防止临床实验室使用冰箱院内交叉感染的主要措施。
Objective To understand the use and contamination of pathogenic microorganism laboratory refrigerators in Hongkou District and to analyze the existing problems in health supervision so as to discuss the corresponding countermeasures. Methods Quantitative research methods were used to analyze the coverage of laboratory-wide refrigerators in Hongkou district and the related personnel survey results, and to analyze the common problems found. Results The use of refrigerators in clinical laboratories has not drawn any attention and is in a regulatory blind spot. Biological tests show that placing the specimens to be processed, that is, positive, negative specimens mix refrigerator total bacterial colonies lower pass rate, frequent use of wet disinfection refrigerator fungi lower pass rate. Conclusions Careful attention should be paid to the cryogenic storage ability of refrigerators, to regulate the storage system, to store the specimens to be treated as far as possible and to adopt suitable methods to sterilize the refrigerator, which is the main measure to prevent the cross infection in the refrigerator in clinical laboratories.
