概括
格拉姆阴性细菌和受感染的骨科植入物显著增加了对重复手术的需求,称为"第二次看",以控制感染. 这一发现有助于规划患者护理和抗生素策略,以获得更好的结果.
科学领域:
- 整形外科手术 整形外科手术
- 传染性疾病 传染性疾病
- 微生物学 微生物学
背景情况:
- 骨科感染通常需要重复的手术除菌和抗菌药物治疗.
- 脱bridement程序的频率,包括"第二次看",有很大的差异.
- 识别与多重除菌相关的病原体对于感染控制至关重要.
研究的目的:
- 调查特定细菌病原体与骨科感染中多次脱bridement程序 ("第二次看") 的要求之间的关联.
- 为了确定重复手术干预的风险因素在治疗骨科感染.
主要方法:
- 分析了2019年至2025年期间进行的三项前性随机对照试验 (RCT) 的复合数据库.
- 协议初始的手术脱bridement与额外的脱bridement只允许持久或渐进的局部感染.
- 用多变量逻辑回归来确定独立的关联.
主要成果:
- 18.8%的骨科感染 (201/1067) 需要多次除bridement手术,平均有两个额外的干预.
- 格拉姆阴性病原体 (28.2%) 和与植入物相关的感染 (25.4%) 显示"第二次外观"的风险最高.

01:26Factors Affecting the Risk of Infection
13.2K
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...

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.

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

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...
