四种常用含氯消毒剂杀菌效果及部分性能的比较

为提高医院医疗器械的清洗和消毒质量,选择合适的化学消毒剂,采用载体定量杀菌试验对 4种常用含氯消毒剂的杀菌效果、稳定性进行了试验比较。结果,以含有效氯 500mg/L的 4种含氯消毒剂溶液对大肠杆菌、金黄色葡萄球菌、作用 15min,杀灭率均为 100%;对白色念珠菌,万福金安消毒剂和经纬三强消毒剂杀菌率达 100%;四环牌清洗消毒剂和 84消毒剂杀菌率分别为 99. 99%和 99. 98%。对不锈钢片、铝片、铜片、碳钢片万福金安基本无腐蚀作用,其它三种消毒剂均存在不同程度的腐蚀作用。

COMPARISON OF GERMICIDAL EFFICACY AND SOME PROPERTIES OF FOUR COMMON CHLORINE-CONTAINING DISINFECTANTS

In order to improve the quality of cleaning and disinfection of medical instruments in hospital and to select suitable chemical disinfectants, carrier quantitative germicidal test was used to compare experimentally the germicidal efficacy and stability of 4 common chlorine-containing disinfectants. Results: The 4 chlorine-containing disinfectant solutions containing available chlorine 500 mg/L with a 15 min contact time killed 100% of Escherichia coli and Staphylococcus aureus. Wan-Fu-Jin-An disinfectant and Jing-Wei-San-Qiang disinfectant killed 100% of Candida albicans, while Si-Huan-brand germicidal detergent and 84 Disinfectant could kill 99.99% and 99.98% of it respectively. Wan-Fu-Jin-An disinfectant was essentially not corrosive to stainless steel coupon, aluminum coupon, copper coupon and carbon steel coupon, while the other 3 disinfectants were corrosive to various degrees.
