目的医院使用２％戊二醛的灭菌效果。方法抽检市售江、浙、沪等８种２％戊二醛产品进行调查。结果其ｐＨ值差异较大，对枯草杆菌黑色变种芽胞杀灭率更是时间悬殊，其中有两种产品在ｐＨ７时作用８小时仍不能达到杀灭率９９．９％的消毒标准，又在３０℃和２０℃时连续２１天测定添加亚硝酸钠的戊二醛的浓度下降十分明显，前者下降率达３１．３％，后者为６．０６％。结论市售２％戊二醛产品质量差异较大，应制订戊二醛的行业标准，为医院提供消毒灭菌可靠保障
The purpose of the hospital use of 2% glutaraldehyde sterilization. Methods Sampling of 8 kinds of 2% glutaraldehyde products from Jiangsu, Zhejiang and Shanghai was investigated. The results of its larger pH value of Bacillus subtilis black spores kill rate is more time difference, of which two products at pH7 for 8 hours still can not achieve the killing rate of 99.9% of the disinfection standards, and 30 The results showed that the concentration of glutaraldehyde added with sodium nitrite decreased obviously when the temperature was 20 ℃ and 21 days. The former decreased 31.3% and the latter 6.06%. Conclusion 2% glutaraldehyde commercially available product quality differences should be developed glutaraldehyde industry standards for the hospital to provide reliable protection of disinfection and sterilization
