概括
在全膝关节整形术 (TKA) 后,塞法林抗生素预防显著降低了围围假肢关节感染 (PJI) 的风险. 这项国家研究发现,与替代抗生素相比,塞法林的使用降低了PJI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
- 药理学 药理学是指药理学的学科.
背景情况:
- 关于选择抗生素和膝关节全关节整形术 (TKA) 后周围假肢关节感染 (PJI) 风险的证据存在矛盾.
- 一个国家数据库被用来评估塞法林与替代抗生素对PJI发病率的影响.
研究的目的:
- 调查塞法林预防是否降低了初级全膝关节整形术 (TKA) 后PJI的风险.
- 为了比较仅接受塞法林,塞法林与另一种抗生素或非塞法林预防的患者之间的PJI率.
主要方法:
- 一个国家数据库 (2016-2022) 被查询到主要的TKA程序 (CPT 27447).
- 分析了超过528,000名TKA患者,根据抗生素预防分类:仅使用塞法索林,塞法索林加另一种抗生素或非塞法索林.
- 90天内的周围假肢关节感染 (PJI) 使用CMS并发症代码进行了鉴定. 用多项逻辑回归来进行分析.
主要成果:
- 单变量分析显示,与非塞法林 (1.0%) 相比,以塞法林为基础的预防治疗的90天PJI率较低 (0.7%).
- 经过调整后的分析表明,仅服用塞法佐林 (OR 0.68) 和服用塞法佐林加另一种抗生素 (OR 0.74) 都与降低PJI的几率有显著关联.
- 这些关联在控制患者人口统计和并发症后仍然具有统计学意义 (P < 0.001).
结论:
- 国家代表性数据证实,与替代抗生素治疗方案相比,塞法林预防显著降低了TKA后90天的PJI风险.
- 外科医生应优先考虑基于塞法林的预防,将患者的过敏视为偏差的主要原因.
- 需要进一步的研究,为患有塞法林过敏或感染风险较高的患者制定最佳的抗生素策略.

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...

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
