概括
四级化合物 (QAC) 湿巾与肥在手部卫生方面的有效性相匹配,在富含蛋白质的条件下优于基于酒精的手部擦拭剂. 这提供了一个可行的替代品,在水稀缺的地方,虽然背部清洁需要改进.
科学领域:
- 微生物学和感染控制
- 公共卫生和卫生.
背景情况:
- 评估四级化合物 (QAC) 湿巾,传统洗手和基于酒精的手部擦拭剂 (ABHRs) 在微生物清除方面的有效性.
- 专注于被蛋白质有机物污染的手,这是医疗机构常见的挑战.
研究的目的:
- 为了比较三种手部卫生方法 (QAC纸巾,洗手,ABHRs) 在减少微生物负载方面的有效性.
- 在模拟有机污染的条件下评估性能.
主要方法:
- 一个交叉试验,涉及15名受过标准化手部卫生技术培训的志愿者.
- 干预措施包括60秒用肥洗手,30秒的ABHR应用和60秒的QAC擦拭使用.
- 手被 Staphylococcus aureus 和牛血清白蛋白 (BSA) 污染; 微生物减少量化为每一个手部区域.
主要成果:
- 在所有手部区域,QAC湿巾显示与肥相比,其细菌去除率不低于肥.
- 在蛋白质环境中,QAC湿巾和肥明显比ABHR更有效.
- 效率因手部区域而异:手指 > 手掌 > 背部,在背部较低的表现下,用于湿巾和肥.
结论:
- 使用60秒协议的QAC湿巾是用肥洗手的可行替代品,特别是在缺水地区.
- 在蛋白质丰富的条件下,ABHRs的有效性降低.
- 在手背部的效率较低表明需要完善卫生技术,以完全去除微生物.

Hand hygiene
4.1K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Handwashing I: Introduction and Types of Equipment
4.5K
Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated....

The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...

Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
