背景:本研究旨在通过个人习惯的去除方法(IARM)和疾病控制与预防中心(CDC)推荐的长袍去除方法,检查3种个人防护服(PPC)去除过程中的身体污染率和环境污染水平。
方法:50位参与者进行了IARM和CDC推荐的长袍去除方法,以去除3种类型的PPC(即,棉质礼服,防水礼服,和塑料围裙)在礼服表面上使用GloGerm模拟胚芽乳液后,以2个单独的时间随机顺序进行。在两个会话之间显示了演示CDC推荐的长袍去除方法的视频。PPC拆卸后,在暗光下通过紫外线扫描计数荧光染色。
结果:在IARM之后,污染物溅到周围,特别是在主题的前面。塑料围裙和棉衣获得了最高和最低的污染危害,分别,到手上,鞋子,和环境。雌性,护士,高级员工的手或鞋子受到严重污染。CDC去除方法更明显地减少了身体和环境污染的小荧光污渍(<1厘米(2)),但不是大的补丁(>1厘米(2)),比IARM。
结论:去除长袍的效果,PPC类型,丢弃PPC位置,感染控制措施的培训,手部卫生,每天都应该考虑特殊的工作鞋。
BACKGROUND: This study aimed to examine the body contamination rates and environmental contamination levels during the removal of 3 types of personal protective clothing (PPC) by the individual accustomed removal method (IARM) and gown removal methods recommended by the Centers for Disease Control and Prevention (CDC).
METHODS: Fifty participants performed IARM and CDC-recommended gown removal methods to remove 3 types of PPC (ie, cotton gown, water resistant gown, and plastic apron) in random order at 2 separate sessions after applying Glo Germ simulated germ lotion on the gown\'s surface. A video demonstrating the CDC-recommended gown removal method was shown between the 2 sessions. After PPC removal, fluorescent stains were counted by an ultraviolet scan under dim light.
RESULTS: Following IARM, contaminants were splashed in the surroundings, particularly on the front part of the subject. The plastic apron and cotton gown obtained the highest and lowest contaminative hazards, respectively, to the hands, shoes, and environment. Females, nurses, and senior staff had serious hand or shoe contamination. The CDC removal method more significantly reduced body and environmental contamination of small fluorescent stains (<1 cm(2)), but not of large patches (>1 cm(2)), than IARM.
CONCLUSIONS: The effect of gown removal, PPC type, discarding PPC location, training of infection control measures, hand hygiene, and special work shoes should be considered daily.
