概括
在创伤复苏后进行血小板输血 (PLT-t) 是常见的. 在中度至重度血小板缺血的患者中,复苏后的PLT-t与较低的死亡率,但较长的重症监护停留时间有关.
科学领域:
- 创伤复苏和重症监护服务
- 血液学和输血医学 血液学和输血医学
背景情况:
- 血小板输血 (PLT-t) 在创伤护理中至关重要,但其在复苏后的作用尚不清楚.
- 了解PLT-t利用和初始复苏阶段后的结果对于优化患者管理至关重要.
研究的目的:
- 描述成人创伤患者在复苏后的PLT-t治疗频率和模式.
- 评估后苏醒PLT-t对血小板数增加和临床结果的影响,包括死亡率和停留时间.
主要方法:
- 一个回顾性研究的成年创伤患者被录取到一个主要的创伤中心.
- 患者接受PLT-t后复苏 (>24小时后受伤) 与没有接受PLT-t后复苏的患者的比较.
- 后勤回归分析以确定后复苏PLT-t与临床结果之间的关联.
主要成果:
- 803名创伤患者中有14%接受了复苏后PLT-t,占所有输血血小板单位的30%.
- 血小板的中位数增加为19×10^9/L,其中24%的输血在24小时内未能提高血小板数量.
- 复苏后的PLT-t在中度至重度血小板缺血的患者中与降低死亡率 (OR 0.42) 相相关,但增加了重症监护停留时间 (系数0.35).
结论:

Formation of the Platelet Plug
8.8K
The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
329
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Introduction to Hemostasis
13.4K
Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
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,...

Structure and Function of Platelets
3.0K
The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

Clot Retraction and Fibrinolysis
8.5K
After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.
