胃镜污染状况调查

目的 了解胃镜污染状况。方法 对使用后的胃镜进行镜内、镜外采样做细菌培养。结果 使用后的胃镜镜内、镜外均存在严重污染，除有鼻咽部正常菌群外，还有较多的条件致病菌，其主要病原菌为酿脓链球菌、黏膜炎莫拉菌、非发酵菌属等。结论 胃镜使用后细菌较多，被污染的大多为人体的正常菌群及一些条件致病菌，应加强对医用胃镜的消毒管理，严格按照国家卫生部《消毒技术规范》要求进行清洗消毒，以免造成因清洗消毒失败而引起的医院感染。

Gastroscope Contamination:Status Investigation

OBJECTIVE To understand the status of gastroscope contamination.METHODS The bacterial(cultivation) of samples derived from inside and outside gastroscope after using was conducted.RESULTS There were heavy(contaminations) inside and(outside) gastroscope after using.Except for normal microbial populations(existing) on pharynx nasalis,many(conditional) pathogenic bacteria had been detected,such as Streptococcus pyogenes,Moraxella catarrhalis,and(nonzymocyte).CONCLUSIONS Many species of bacteria are detected inside and outside(gastroscope) after using.They are normal microbial populations in pharynx nasalis and some conditional pathogenic bacteria.It is (necessary) to strengthen regulation of gastroscope cleaning and disinfection. We should follow Technological Regulations of Disinfection(Ministry of Health,2004) to clean and disinfect endoscope strictly in order to avoid(hospital) acquired infection due to insufficient cleaning and disinfection.
