概括
与传统的化学清洁相比,操作员驱动的UV-C光消毒显著减少了手术室的污染. 紫外线处理更快,更有效,特别是当它被用作主要消毒方法时.
科学领域:
- 控制与医疗保健相关的感染
- 在医疗保健机构的环境卫生.
- 微生物学和消毒技术.
背景情况:
- 鼻腔病原体可以在手术室 (OR) 表面上持续存在,抵御传统的清洁方法.
- 有效的终端消毒对于预防医疗相关感染至关重要.
研究的目的:
- 为了比较传统的化学终端消毒的有效性与操作员驱动的OR表面消毒的UV-C光装置.
- 评估连续消毒处理 (化学和UV-C) 的添加效应.
主要方法:
- 一项涉及40个手术室的随机交叉研究,比较化学消毒后进行UV-C (A组) 与UV-C后进行化学消毒 (B组).
- 在每个消毒步骤之前和之后,从16个地点采集了葡萄球菌培养物.
- 评估了消毒的彻底性和时间效率.
主要成果:
- 经营者驱动的UV-C消毒将污染现场减少了50%以上 (P<0.001),显著优于化学消毒.
- 化学清洗后的UV-C处理几乎将剩余污染物减少了一半 (P<0.001).

Methods of Sterilization II: Chemical Methods

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Chemical Agents for Microbial Control
54
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...

Cleaning, Sterilization, and Disinfection
7.0K
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...

Hand hygiene
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.

Physical Methods for Controlling Microbial Growth: Radiation and Filtration
54
Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
