概括

手术感染,特别是创伤或植入物感染,表现出明显的微生物模式. 虽然多微生物感染很常见,但高水平的抗生素耐药性很少见,指导向治疗.

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:

手术感染是一种严重的并发症,特别是在创伤后或使用内部固定装置时.
关于手术感染中的特定微生物特征和抗菌素耐药性模式的数据有限.

研究的目的:

描述手术队伍中的微生物景观和抗菌素耐药性感染模式.
根据临床情景来区分这些概况,例如创伤与内部固定装置感染.

主要方法:

一项对72名手术感染患者的回顾性观察性研究 (2024年1月至2025年6月).
微生物分离物和抗菌素敏感性的分析.
根据临床情景 (创伤,内部固定) 和感染类型 (单微生物,多微生物) 的分层.

主要成果:

与创伤相关的感染 (77.8%) 往往是单微生物 (64.3%),主要是金黄色葡萄球菌 (25.0%的甲素耐药).
多微生物创伤感染复杂但耐药性低;内部固定感染 (22.2%) 更多的是多微生物.
没有发现扩展谱β-乳糖酶产生的肠杆菌或耐卡巴胺的有机体.

结论:

这项研究为手术感染提供了关键的微生物学数据,解决了骨科文献中的差距.
感染概况因临床背景和微生物复杂性而有显著差异.
高级耐药性的低率表明,局部监测是实证治疗决策的关键.

Hand hygiene

Hand hygiene

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.

Healthcare Associated Infections II: Preventive Measures

Healthcare Associated Infections II: Preventive Measures

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.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

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...
