概括
来自静脉动脉外体膜氧化 (VA-ECMO) 的脱与全身炎症反应综合征 (SIRS) 有关. 支持炎症的细胞因子水平,包括TNF-α,在SIRS后VA-ECMO解锁患者中没有显著变化.
科学领域:
- 临界护理医学 临界护理医学
- 心血管外科心血管外科
- 免疫学 免疫学 免疫学
背景情况:
- 来自静脉动脉外体膜氧化 (VA-ECMO) 的脱通常在全身炎症反应综合征 (SIRS) 之前发生.
- 与SIRS后VA-ECMO解相关的特定细胞因子概况尚不清楚.
研究的目的:
- 在VA-ECMO脱后经历SIRS的患者中研究促炎性细胞因子水平的变化.
- 为了确定传统的炎症调解剂是否会在VA-ECMO撤销后引发SIRS发作.
主要方法:
- 一项前性观察性研究,涉及30名成年患者,在VA-ECMO脱后24小时内发生SIRS.
- 血中介质素 (IL) -1α,IL-1β,IL-6和瘤亡因子-α (TNF-α) 的测量在基线和解禁后1,12和24小时.
- 使用重复测量ANOVA进行统计分析,以评估时间性细胞因子水平变化.
主要成果:
- 在24小时的解毒后期间,IL-1α,IL-1β或IL-6水平没有显著变化.
- 与基线相比,瘤亡因子-α (TNF-α) 在脱后24小时显示出具有统计学意义的下降 (p=0.044).
结论:
- 在VA-ECMO脱后,SIRS患者的关键促炎细胞因子的血水平在很大程度上保持稳定.
- 这些发现表明,在这种情况下,SIRS的表现可能不是直接由传统的促炎细胞因子的激增驱动的.
- 需要进一步的研究,以探索可替代的炎症调解剂或有助于SIRS后VA-ECMO解化的机制.

Inflammatory Response
15.8K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Inflammatory Response I: Vascular and Cellular
15.8K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Inflammatory Response II: Inflammatory Exudate and Tissue Repair
7.3K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

Tracheostomy Decannulation
1.1K
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Regulation of Hematopoietic Stem Cells
3.9K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
