【摘要】：目的探讨过氧化氢对口腔综合治疗台水路(DUWL)污染的消毒效果。方法在某市一家三甲综合医院采用单中心随机对照试验,比较20 g/L过氧化氢对DUWL污染的消毒效果。在13台牙科治疗台中,选择同一种类型的12台,应答率为92.31%(12/13)。干预组和对照组由电脑生成随机数字,并采用盲法和隐匿分组开展实验(干预组,20 g/L过氧化氢冲洗,6台;对照组:安慰剂冲洗,6台)。分别采样四种水样:水源水、手机水、喷枪水和漱口水。相对危险度(RR)和95%可信区间(CI)被用来评价干预效果。参照GB 5749《生活饮用水卫生标准》,细菌总数不超过100 cfu/ml为评判标准。结果本实验共采集36份水样(手机水、冲洗水各3份)。手机水、喷枪水和漱口水为9 950.00 cfu/ml(4 307.00~25 300.00 cfu/ml)、360.00 cfu/ml(149.00~1 720.00 cfu/ml)和4 250.00cfu/ml(1 850.00~11 925.00 cfu/ml)。本次干预研究发现,采用20 g/L过氧化氢可以显著降低83%微生物污染风险(RR=0.17,95%,CI=0.06-0.47)。随访研究显示,当随访24 h后,细菌总数超过100 cfu/ml。结论 20 g/L过氧化氢溶液可以显著降低DUWL微生物污染。然而,这种效果维持时间较短,应定期监测DUWL细菌总数。
[Abstract]:Objective to study the disinfection effect of hydrogen peroxide on DUWL contamination of oral cavity comprehensive treatment platform. Methods A single center randomized controlled trial was used in a Sanjia General Hospital in a city. The disinfection effect of 20 g / L hydrogen peroxide on DUWL contamination was compared. In 13 dental treatment units, 12 of the same type were selected, and the response rate was 92.31 / 12 / 13. The intervention group and the control group were randomly generated by computer. The experiment was carried out by blind method and occult group (intervention group, 20 g / L hydrogen peroxide, 6 cases; control group, placebo, 6 sets). Four kinds of water samples were sampled: source water, mobile phone water, and so on. Spray gun water and mouthwash. Relative risk (RR) and 95% confidence interval (CI) were used to evaluate the effect of intervention. With reference to GB5749, the total bacterial count was not more than 100 cfu/ml. Results 36 water samples (mobile phone water) were collected in this experiment. Three portions of rinse water were used for mobile phone water, spray gun water and mouthwash for 9 950.00 cfu/ml(4 307.00N 25 300.00 cfur / ml 360.00 cfu/ml(149.00~1 720.00 cfur / ml) and 4 250.00cfuml / ml 1 850.00cfur 11 925.00 cfuml / ml respectively. This intervention study found that 20 g / L hydrogen peroxide could significantly reduce the risk of microorganism pollution by 83% RRN 0.1795% CI 0.06-0.470.The results showed that. When followed up for 24 h, the total number of bacteria exceeded 100 cfur 路ml. Conclusion 20 g / L hydrogen peroxide solution can significantly reduce the microbial contamination of DUWL. However, the duration of this effect is relatively short, and the total number of DUWL bacteria should be monitored regularly.
