年龄显著影响创伤患者的血栓生成动力学,老年人表现出延长的启动和高峰时间. 这些发现突出了受伤后凝血的年龄相关差异,可能会影响血栓形成风险.
科学领域:
- 凝血科学是一门凝血科学.
- 创伤研究研究创伤研究
- 老年医学 老年医学
背景情况:
- 创伤损伤改变了凝血,增加了长期的血栓形成风险.
- 年龄对创伤后凝血生物标志物的影响尚不清楚.
- 血栓生成动力学预测静脉血栓栓塞.
研究的目的:
- 为了研究血栓生成动力学的与年龄相关的差异.
- 在创伤患者的血栓生成的特征跨越年龄范围.
主要方法:
- 从174名创伤患者 (年龄3-94岁) 收集了血样本.
- 使用校准自动血栓图 (CAT) 测量血栓生成动力学,评估滞后时间 (LT) 和达到峰值的时间 (ttPeak).
- 使用克鲁斯卡尔-瓦利斯,斯皮尔曼相关性和多变量回归分析数据.
主要成果:
- 与成人和老年患者相比,儿科患者的LT和ttPeak时间较短.
- LT和ttPeak与患者年龄有显著的相关性 (p < 0.001).
- 在多变量模型中,年龄,损伤严重程度得分和输血状态与LT和ttPeak有关.
结论:
- 创伤患者表现出与年龄相关的血栓生成启动和峰值的延长.
- 需要进一步的研究来阐明年龄特异性血栓生成在创伤后血栓性并发症中的作用.

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
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...
Clot Retraction and Fibrinolysis
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,...
