摘　　要：目的了解2019年新疆乌鲁木齐市不同级别医疗机构口腔科治疗用水微生物污染状况,为制定乌鲁木齐市地方标准提供参考依据。方法采集乌鲁木齐市35家不同级别医疗机构口腔科治疗用水样,以营养琼脂培养基增菌并分类,按《生活饮用水质卫生规范》GB 5749-2006和《血液透析及相关治疗用水》YY 0572-2015规定的标准判定治疗用水是否合格。结果共采集口腔科治疗用水水样280份,菌落总数合格190份,铜绿假单胞菌、洋葱伯克霍尔德菌和少动鞘氨醇杆菌检出率分别为9.31%,5.16%和11.53%。以≤100 cfu/ml为合格标准,口腔综合治疗椅出水总合格率为67.86%,其中二级及以上医院、社区医院和口腔诊所等医疗机构合格率分别为87.50%,52.08%和53.57%;反渗透净化系统、过滤式自来水系统、独立储水罐(瓶)供应系统等3种不同处理方式合格率分别为88.89%,57.14%和58.70%。结论二级及以上医院口腔治疗用水合格率高于社区医院和口腔诊所,反渗透净化系统处理的口腔科治疗用水卫生质量优于其他处理方式,卫生监督部门应加强医疗机构口腔治疗用水的监督管理,保证定期与疾病预防控制部门联合监督监测。Objective To understand the microbial contamination status of treatment water in the departments of stomatology of medical institutions at different levels in Urumqi, Xinjiang in 2019, so as to provide reference for formulating the local standards in Urumqi. Methods The samples of treatment water were collected from 35 medical institutions at different levels in Urumqi, enriched with nutrient agar culture medium and classified. The qualification of treatment water were determined according to the Standards for Drinking Water Quality(GB 5749-2006) and Water for Hemodialysis and Related Therapy(YY 0572-2015). Results Totally 280 water samples were collected from the department of stomatology,and 190 of them were qualified for total bacterial count. The detection rates of Pseudomonas aeruginosa, Burkholderia cepacia and Sphingomonas oligozootica were 9.31%, 5.16% and 11.53%, respectively. Taking ≤100 cfu/ml as the qualified standard, the total qualified rate was 67.86% in the effluent water of oral comprehensive treatment chair, and the qualified rates were 87.50%, 52.08% and 53.57%, respectively in the hospitals at secondary level and above, community hospitals and dental clinics, and 88.89%, 57.14% and 58.70%, respectively with three different processing methods of the reverse osmosis purification system, filtered tap water system and independent water storage tank(bottle) supply system. Conclusions The qualified rate of dental treatment water is higher in secondary and above hospitals than in community hospitals and dental clinics, and the sanitary quality is better in the dental treatment water processed by reverse osmosis purification system than that processed with other methods. The health supervising departments should strengthen the supervision and management of dental treatment water in medical institutions, and ensure to conduct regularly joint supervision and monitoring with institutions of disease control and prevention.
