概括
培养负性败血症与性休克患者的较高死亡率有关,尽管看似适当的抗生素使用. 这挑战了目前关于这些病例实证抗生素治疗有效性的指导方针.
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
- 临床微生物学 临床微生物学
背景情况:
- 培养阳性败血症和培养阴性败血症之间的临床差异和结果尚未得到充分确立.
- 需要大规模的数据来澄清这些区别.
研究的目的:
- 调查培养负性与培养阳性败血症的临床特征和结果.
- 为了确定培养负性是否会影响预后,特别是在败血症休克中.
主要方法:
- 一项前性队列研究,使用来自韩国败血症联盟注册表 (21个ICU,20家医院) 的数据.
- 包括从2019年9月到2021年12月满足败血症-3标准的3501名患者.
- 在培养阳性和培养阴性败血症组之间比较临床特征,治疗遵从性和死亡率.
主要成果:
- 培养负性败血症患者 (37%) 普遍呈现较轻重的疾病,但呼吸衰竭的发病率较高.
- 尽管对液体复苏的遵守程度较低,并且在培养负性败血症中早些时候使用了血管压缩剂,但住院死亡率相似.
- 然而,培养阴性败血栓休克患者的死亡率较高 (45.1%),培养阴性独立预测预后不佳 (OR: 1.462).
结论:
- 培养消极性与性休克死亡率的增加有关,这与观察到的经验性抗生素明显更高的适当性相矛盾.
- 目前评估经验抗生素适用性的标准可能不足以治疗培养负性败血症.
- 需要进一步的研究来完善培养负性败血症的治疗策略,特别是在败血性休克中.

Sputum Studies II: Culture and Sensitivity
255
Description
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,...

Sputum Studies I: Gram Stain, cytology, and Acid-fast smear and culture
163
Sputum studies are a critical part of diagnosing and treating numerous respiratory conditions. These studies involve obtaining sputum samples for analysis to identify pathogenic organisms and assess the presence of abnormal cells indicative of malignant conditions. This lesson will delve into three fundamental sputum studies: Gram Stain, Cytology, and Acid-fast Smear and Culture.
Gram Stain
The Gram Stain is an integral part of sputum studies. It involves the staining of sputum, which permits...
