概括
手术标记笔可能含有细菌,造成患者传染的风险. 即使在进行波维-准备后,一些笔也显示出细菌殖民,突出显示了整形外科手术中潜在的感染控制缺口.
科学领域:
- 感染控制 感染控制
- 手术安全实践手术安全实践
- 微生物学 微生物学
背景情况:
- 术前标记对于防止错位手术至关重要,正如联合委员会通用协议所要求的那样.
- 之前的研究表明,抗甲素黄金葡萄球菌 (MRSA) 可以在可重复使用的手术标记笔上存活,这可能导致传播.
- 尽管存在担忧,但联合委员会没有发现与这些标记相关的术后感染风险增加.
研究的目的:
- 为了研究细菌殖民手术标记笔的细菌殖民,特别是在整形手术群体内.
- 评估标准波维-制剂在消除标记位置的细菌方面的有效性.
主要方法:
- 整形外科医生使用的十种手术标记笔培养了有氧和无氧细菌.
- 然后使用这些笔来标记模拟的切口部位,然后进行波维-准备.
- 从准备好的地点再次采集培养物,结果与五个无菌对照笔进行了比较.
主要成果:
- 对照笔没有显示细菌生长.
- 从使用过的笔中直接培养发现凝结酶阴性葡萄球菌和Pseudomonas aeruginosa.
- 来自标记位置的预制后培养在两个实例中产生了凝结酶负型葡萄球菌,但没有Pseudomonas
结论:

3.4K
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.

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

01:28Asepsis
2.2K
The condition of being free from disease-causing living pathogens is asepsis. Aseptic techniques include a set of standard practices to achieve asepsis. An example is the regular environmental cleaning of all parts of the healthcare facility and hand hygiene at home before preparing or eating food. Medical and surgical asepsis in healthcare practice protects patients from harmful pathogens, minimizes the risk of contamination of susceptible sites, and reduces the risk of infection transmission.

01:26Factors Affecting the Risk of Infection
12.0K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
