Universal precautions require that perioperative health care personnel wash their hand before and after all patient contact. Time constraints, however, can make adhering to universal precautions, including proper hand washing, difficult. Some perioperative health care workers, therefore, routinely use rise-free hand sanitizers to supplement normal hand washing. This study evaluated immediate and persistent antimicrobial effectiveness of two alcohol--containing hand sanitizers and a novel surfactant, allantoin, benzalkonium chloride (SAB) hand sanitizer using a federally approved effectiveness protocol. Results indicate that all three products were equally effective after a single application. After repeated use, the alcohol-containing sanitizers did not meet federal performance standards, and the alcohol-free sanitizer did. These properties and others illustrated in this article indicate that the nonflammable, alcohol-free SAB hand sanitizer is the most favorable of the rise-free hand sanitizer formulas for normal hand washing.
通用预防措施要求围手术期医护人员在每次接触患者前后都要洗手。然而，时间限制可能使遵守包括正确洗手在内的通用预防措施变得困难。因此，一些围手术期医护人员经常使用免冲洗洗手液来补充常规洗手。本研究使用联邦批准的有效性方案，评估了两种含酒精洗手液和一种新型表面活性剂尿囊素、苯扎氯铵（SAB）洗手液的即时和持久抗菌效果。结果表明，单次使用后，这三种产品的效果相同。重复使用后，含酒精的洗手液未达到联邦性能标准，而不含酒精的洗手液达到了标准。本文阐述的这些特性及其他特性表明，对于常规洗手而言，不可燃的不含酒精的SAB洗手液是最有利的免冲洗洗手液配方。
