概括
周围假肢感染的复发与更高的感染严重性得分和更有毒的病原体有关. 单阶段的修订不会显著增加复发风险,即使是严重的感染.
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
- 生物医学工程 生物医学工程
背景情况:
- 周围假肢关节感染 (PJI) 治疗的目的是根除和预防复发.
- 2018年关于骨科感染的国际共识会议 (ICMOI) 建立了感染严重性 (IS) 评分,以分层PJI病例.
- 了解影响PJI复发的因素对于优化治疗策略至关重要.
研究的目的:
- 评估ICMOI感染严重性 (IS) 评分对PJI复发的影响.
- 评估单阶段修复手术对PJI复发率的影响.
- 确定感染性生物在PJI复发中的病原性作用.
主要方法:
- 对PJI (2004-2020年) 157次修复手术的回顾性审查,至少2年后续.
- 病例按IS分数 (不太可能,可能,确定的/可能的感染) 根据2018年ICMOI标准进行分类.
- 基于IS分数,单阶段修订和微生物毒性的复发率分析.
主要成果:
- 较高的IS分数增加了复发率:2.3% (不太可能),12% (可能) 和17.4% (确定/可能).
- 单阶段审查显示,整体复发率为5.0%,确定的/可能感染病例为5.9%.
- 高毒性病原体,如耐甲基黄金葡萄球菌的复发率为30.8%,而其他生物体的复发率为4.0-5.9%.
结论:
- 增加感染严重性 (IS) 评分和更多的毒性微生物与更高的周围假肢感染复发率有关.
- 单阶段修复手术不会显著增加复发风险,即使在IS分数较高的患者中也是如此.
- 感染生物的致病性是PJI复发的一个重要因素.

Factors Affecting the Risk of Infection
11.8K
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...

Healthcare Associated Infections II: Preventive Measures
2.6K
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...
