目的:使用欧洲标准(EN1500)方法评估各种市售酒精型洗手液(ABHS)的抗菌效果,并使用膜过滤方法进行ABHS测试。
方法:一项横断面观察性研究。研究的地点和持续时间:微生物实验室的质量控制部分,阿加汗大学医院,卡拉奇,巴基斯坦,2023年2月至4月。
方法:将14种商业上可广泛使用的手部消毒剂的功效定义为减少微生物生长。使用EN1500欧洲标准测试和膜过滤方法测定。
结果:大多数(92.8%)ABHS显示出显着的细菌减少,除了用EN1500方法测试的一个ABHS。通过膜过滤方法仅测试了六种ABHS产品,因为手消毒剂的高粘度会损坏滤膜。
结论:在通过可靠的测试方法评估洗手液的功效时继续保持警惕,对于确保公众健康和防止传播可能损害手卫生习惯的误导性产品至关重要。
背景:洗手液,欧洲标准,膜过滤法,抗菌功效。
OBJECTIVE: To evaluate the antibacterial efficacy of various commercially available alcohol-based hand sanitisers (ABHS) using European standard (EN 1500) method and perform ABHS testing with membrane filtration method.
METHODS: A Cross-sectional observational study. Place and Duration of the Study: Quality Control Section of the Microbiology Laboratory, The Aga Khan University Hospital, Karachi, Pakistan, from February to April 2023.
METHODS: Efficacy of 14 commercially and widely accessible hand sanitisers was defined as reducing micro-organism growth. It was determined using the EN 1500 European standard test and membrane filtration method.
RESULTS: Majority (92.8%) ABHS showed a significant bacterial reduction except one ABHS tested with the EN 1500 method. Only six ABHS products were tested through the membrane filtration method because high viscosity of hand sanitisers was causing damage to filter membranes.
CONCLUSIONS: Continued vigilance in evaluating hand sanitiser\'s efficacy through robust testing methods is essential to ensure public health and prevent the dissemination of misleading products that may compromise hand hygiene practices.
BACKGROUND: Hand sanitisers, European standard, Membrane filtration method, Antibacterial efficacy.
