身体外膜氧化 (ECMO) 可以通过激活纤维溶解来增加出血风险. 在ECMO患者出血事件之前,D-二聚合物和组织等离子体激活剂 (tPA) 水平的升高表明存在因果关系.
科学领域:
- 心血管研究研究心血管研究
- 血液学 血液学 血液学
- 临界护理医学 临界护理医学
背景情况:
- 身体外膜氧化 (ECMO) 与显著的出血风险有关.
- ECMO对身体的凝块溶解系统 (纤维解析) 的确切影响尚不清楚.
研究的目的:
- 检查ECMO治疗患者的纤维解析标志物随时间的推移如何变化.
- 调查这些变化与出血事件之间的关系.
主要方法:
- 患者接受静脉和静脉动脉ECMO的前性观察研究.
- 纤维解析标记物的纵向测量,包括组织等离子体激活剂 (tPA),等离子体激活剂抑制剂-1 (PAI-1) 和D-二极管.
- 在ECMO植入前,植入期间和植入后分析标记物动态.
主要成果:
- 在ECMO患者中,tPA,D-二聚合物和PAI-1的含量增加,与正常水平相比,等离子素的含量减少.
- 在出血之前,出血患者的D-二聚合物和tPA水平上升,与不出血患者不同.
- 超过0.304nM的tPA度显著预测出血事件 (OR 4.92).
结论:
- 在ECMO期间接触激活有助于纤维素分解,特别是在出血的患者中.
- 这种机制可能是ECMO患者出血的直接原因.
- 研究结果表明,在ECMO期间管理出血的新疗法可能是潜在的目标.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...
