摘　　要：目的了解北京市三级医院内镜超声微探头清洗消毒现状。方法采用便利抽样法抽取北京市51所三级医院,对内镜中心护士长进行问卷调查,调查内容包括内镜超声微探头预处理、清洗、消毒、灭菌、生物学检测、消毒追溯、储存维修等情况。结果51所三级医院中甲等医院33所,乙等医院18所。76.47%(39所)的医院对使用后的超声微探头进行床旁预清洗,内镜超声微探头床旁预处理方式主要包括酶液湿巾擦拭(38.47%,15/39)和乙醇湿巾擦拭(30.77%,12/39);96.08%(49所)的医院对超声微探头进行手工清洗,手工清洗方法以“酶洗-擦洗-擦干”为主(58.82%,30所)。96.08%(49所)的医院对使用后的微探头进行消毒,以化学消毒剂浸泡消毒为主要方法(65.31%,32所);43.14%(22所)的医院对微探头进行灭菌,灭菌方法主要为0.2%~0.35%过氧乙酸浸泡10~15 min(77.27%,17/22);41.18%(21所)的医院定期对微探头进行生物学监测;37.25%(19所)的医院对微探头的清洗消毒流程进行追溯;88.24%(45所)的医院定期对微探头进行检查、保养、维修。结论北京市51所三级医院对内镜超声微探头的预处理、清洗、消毒、灭菌及生物学监测情况存在较大差异,建议尽快制定相关专家共识或指南,从而规范内镜超声微探头的清洗消毒工作。Objective To investigate the current status of cleaning and disinfection of endoscopic ultrasound microprobes in tertiary hospitals in Beijing.Methods 51 tertiary hospitals in Beijing were selected with convenience sampling method,and a questionnaire survey was conducted on head nurses in endoscopy centers,the investigation included pre-treatment,cleaning,disinfection,sterilization,biological testing,disinfection traceability,storage and maintenance of endoscopic ultrasound microprobes.Results Among the 51 tertiary hospitals,33 were first-class hospitals and 18 were second-class hospitals.76.47%(n=39)of hospitals performed bed-side pre-cleaning on ultrasound microprobes after use,bed-side pre-treatment methods for endoscopic ultrasound microprobes mainly included enzyme solution wiping(38.47%,15/39)and ethanol wiping(30.77%,12/39);96.08%(n=49)of hospitals performed manual cleaning for ultrasound microprobes,with“enzyme wash-scrub-dry”as the main method(58.82%,n=30);96.08%(n=49)of hospitals disinfected microprobes after use,with chemical disinfectant immersion as the main methods(65.31%,n=32);43.14%(n=22)of hospitals sterilized the microprobes,and the main method of sterilization was immersion in 0.2%-0.35%peroxyacetic acid for 10-15 minutes(77.27%,17/22);41.18%(n=21)of hospitals regularly conducted biological monitoring on microprobes;37.25%(n=19)of hospitals traced the cleaning and disinfection process of microprobes;88.24%(n=45)of hospitals regularly inspected,maintained,and repaired microprobes.Conclusion The pre-treatment,cleaning,disinfection,sterilization,and biological monitoring of endoscopic ultrasound microprobes in 51 tertiary hospitals in Beijing varies significantly,and it is recommended that a relevant expert consensus or guideline be formulated as early as possible,so as to standardize the cleaning and disinfection of endoscopic ultrasound microprobes.
