概括
在全膝关节整形手术 (TKA) 之前的关节内注射 (IAI) 增加了感染风险,即使没有皮质类固醇. 推推迟TKA至少3个月后任何IAI是为了降低感染率.
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
- 生物医学数据科学 生物医学数据科学
背景情况:
- 在全膝关节整形手术 (TKA) 之前对皮质类固醇进行关节内注射 (IAI) 与TKA后感染风险更高有关.
- 建议的机制包括局部免疫抑制和物理屏障破坏.
- 与非皮质类固醇IAI或简单的愿望相关的风险仍然不清楚.
研究的目的:
- 调查非皮质类固醇IAI的时间与TKA后感染风险之间的关联.
- 为了确定是否简单的愿望或非皮质类固醇注射增加感染风险,相比TKA之前没有注射.
主要方法:
- 对2017-2022年期间的TKA程序进行国家索赔数据库 (>4200万条记录) 的分析.
- 在TKA前6个月内接受IAI (富血小板血,干细胞,甲酸,吸收) 的患者的鉴定.
- 根据最后一次IAI (1,3,或TKA前6个月) 的时间对患者进行分层.
主要成果:
- 在232,342名TKA患者中,有8,019名 (3.5%) 在6个月内接受了IAI.
- 需要手术除菌的感染率最高的是1个月内IAI (7.6%),其次是3个月 (4.6%) 和6个月 (2.2%).
- 在6个月内没有IAI的患者感染率最低 (1.4%).
结论:
- 在TKA之前的IAIs/aspirations会增加感染风险,不论皮质类固醇含量如何.
- 风险特别明显,当IAI在TKA后3个月内使用时.
- 外科医生应该考虑在IAI后推迟TKA长达3个月,以减轻感染风险.

Factors Affecting the Risk of Infection
12.3K
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
2.8K
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...
