概括
手术前的贫血会增加发生并发症的风险,包括膝关节全关节整形术 (TKA) 后的周围假肢关节感染 (PJI). 维持适当的血红蛋白水平对于更好的外科手术结果至关重要.
科学领域:
- 整形外科手术 整形外科手术
- 麻醉学 麻醉学
- 内部医学 内部医学
背景情况:
- 手术前贫血是全膝关节整形术 (TKA) 后不良结果的已知危险因素.
- 世界卫生组织通过血红蛋白水平<12.0 g/dL (女性) 和<13.0 g/dL (男性) 来定义贫血.
- 评估手术前血红蛋白对早期TKA并发症的确切影响至关重要.
研究的目的:
- 评估手术前血红蛋白水平与选择性TKA患者早期术后不良事件的风险之间的关联.
- 确定特定的血红蛋白值,与TKA后的并发症率增加有关.
- 分析连续血红蛋白值与周围假肢关节感染 (PJI),医疗和手术并发症的发生率之间的关系.
主要方法:
- 利用大型住院和门诊数据库识别了61,857名初级TKA患者 (2016-2021年) 与手术前血红蛋白数据.
- 采用多变量逻辑回归和受限立方线来建模血红蛋白与90天并发症风险之间的关系.
- 确定了与显著增加PJI风险相关的临界血红蛋白变化点.
主要成果:
- 在血红蛋白<13.0 g/dL (男性) 或<12.7 g/dL (女性) 的患者中,观察到PJI,综合医学和手术并发症的风险显著增加.
- 血红蛋白10g/dL的患者面临1.86倍增加的PJI风险,2.72倍增加的医学并发症风险和2.16倍增加的手术并发症风险.
- 在血红蛋白值超过13.0g/dL时,没有检测到不良事件的风险增加.
结论:
- 术前贫血与选择性TKA后的早期术后不良结果 (包括PJI) 的增加显著相关.
- 需要进行进一步的研究,以调查纠正手术前低血红蛋白是否可以降低并发症率.
- 低血红蛋白可以作为潜在的慢性疾病的替代标记,从而提高术后风险.

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 create...
