概括
对于无针连接器 (NCs),75%的乙醇与乙醇中的2%的化甘 (CHG) 在消毒方面同样有效. 较长的至少15秒的擦洗时间提高了门诊环境中的脱污效率.
科学领域:
- 感染控制 感染控制
- 微生物学 微生物学
- 护理实践 护理实践
背景情况:
- 无针连接器 (NC) 对于中央静脉通道至关重要,但如果被污染,可能会造成血液感染的风险.
- 目前关于NC消毒的指导方针不一致,影响了护理实践的标准化.
- 75%的乙醇在中国被广泛使用,但与乙醇中的2%的基酸 (CHG) 相比,其有效性需要进一步评估,特别是在门诊环境中.
研究的目的:
- 为了比较75%乙醇与乙醇中2%的CHG在无针连接器中的脱污效率.
- 评估不同磨擦时间 (5,10和15秒) 对NC清除污染的影响.
- 提供证据,用于在门诊机构标准化NC消毒协议.
主要方法:
- 一项因子随机对照试验涉及来自111名成年癌症患者的360名NC.
- NCs被随机分配到六个协议:75%的乙醇或2%的乙醇中CHG,用5,10或15秒的擦洗.
- 微生物培养评估了消毒前后的污染.
主要成果:
- 在80.6%的NC中观察到基线污染.
- 在75%乙醇和乙醇中的2%CHG之间没有发现明显的除污效率差异 (P>0.05).
- 与5秒和10秒的协议相比,15秒的擦拭持续时间显示出更高的疗效 (P=0.024).
结论:
- 75%的乙醇相当于乙醇中的2%的CHG,用于消毒无针连接器.
- 建议至少擦拭15秒,以获得最佳的净化.
- 结果支持标准化擦拭持续时间和优化资源分配NC消毒在不同的临床环境中,特别是在使用75%乙醇的门诊患者群体.

Hand hygiene
3.1K
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.

Cleaning, Sterilization, and Disinfection
6.4K
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...

Methods of Sterilization II: Chemical Methods
6.0K
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,...

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition
42
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
