120份戊二醛与酸性氧化电位水用于软式内镜消毒的对比研究

Comparative Study of Glutaraldehyde and Electrolyzed Acid Water on the Disinfection of the Soft Endoscope:120 Cases Analysis

目的对比研究戊二醛与酸性氧化电位水两种软式内镜消毒方式的效果。方法对软式内镜进行现场消毒试验,戊二醛组60份(胃镜43份,肠镜17份);酸性氧化电位水组60份(胃镜37份,肠镜23份),采用现场采样监测法对其两组消毒后的内镜进行生物学监测,对比分析其消毒效果、时间、经济成本及腐蚀性。结果两组共采样检测120份,未检出阳性标本;戊二醛组总消毒时间平均为23.5 min、酸性氧化电位水组总消毒时间为10 min;戊二醛组每月消耗戊二醛折合人民币约9180元,酸性氧化电位水组每月消耗工业盐折合人民币约108元;两组均未发现对内镜有明显腐蚀性。结论戊二醛和酸性氧化电位水两组消毒方法均可达到消毒要求,而酸性氧化电位水消毒法相比于戊二醛消毒法更省时、成本更低廉和环保。

OBJECTIVE To compare the effects of Glutaraldehyde（GA） and Electrolyzed Acid Water（EAW） on the disinfection of the soft endoscope.METHODS The field tests for the digestive endoscope disinfection： GA group,a total of 60 cases（Gastroscopy 43 cases,17 cases of colonoscopy）;EAW group,totaling 60 cases（37 cases of gastroscopy,colonoscopy 23）.RESULTS None of samples from both groups was positive for test of bacterial culture.GA group had a more time comsumption than EAW group（20.6 VS 10.4,P〈0.05;27.3 VS 10.4,P〈0.05）,while EAW group had a less cost than GA group（102.6 VS 1.8,P〈0.05;204.3 VS 1.8,P〈0.05）,and no chemical injury was found on the surface of endoscope in both groups.CONCLUSIONS The two methods have shown excellent results in the effectiveness of the disinfection.At the same time,both of which have not been found to have corrosive effects on soft endoscope.EAW is superior to GA in view of disinfection speed,cost accounting,and environmental protection.
