大约25%的败血症患者符合败血症-3标准,可能因其他原因导致器官功能障碍. 识别患有免疫反应失调的患者可以改善败血症治疗和结果.
科学领域:
- 关键护理医学 关键护理医学
- 传染性疾病 传染性疾病
- 免疫学 免疫学 免疫学
背景情况:
- 败血症根据败血症-3标准被定义为由于宿主对感染反应失调而导致的危及生命的器官功能障碍.
- 由于测量宿主反应的困难,诊断败血症可能具有挑战性,可能导致因伴随性疾病或直接感染影响而导致器官功能障碍的患者误诊.
- 这项研究旨在在败血症患者中区分器官功能障碍的原因,区分失调的免疫反应和替代解释.
研究的目的:
- 根据"败血症-3"标准对被诊断患有败血症的患者进行鉴定.
- 为了确定这些患者的器官功能障碍是由于免疫反应失调或另一个原因.
- 为了提供更精确的败血症诊断和治疗策略.
主要方法:
- 进行了一项单一中心,回顾性,观察性研究.
- 分析了2022年1月1日至2022年12月31日期间因败血症住院的373名患者.
- 审查了临床,实验室和成像记录,以确定器官功能障碍的原因.
主要成果:
- 在373个病例中,303个 (81.2%) 符合败血症-3标准.
- 显著的比例,78名患者 (25.7%),对器官功能障碍有另一个解释,包括并发症恶化 (9.2%) 和直接感染影响 (13.9%).
- 与可能有免疫反应失调 (34.7%) 的患者相比,具有替代解释的患者的急性病情较小,住院死亡率较低 (19.2%).
结论:
- 大约四分之一的被诊断患有败血症并符合败血症-3标准的患者可能没有器官功能障碍,主要是由免疫反应失调驱动的.
- 细化败血症诊断以关注可能有免疫反应失调的患者,可以提高治疗效率.
- 这种方法可能会改善败血症护理和患者的治疗结果.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
