概括

早期冷藏血小板输血对于创伤患者来说是可行的,也是安全的. 虽然这种方法没有显著降低24小时死亡率,但其安全性与标准复苏相美,为出血性休克管理提供了可行的选择.

科学领域:

创伤复苏的复苏治疗方法
输血输血输血输血输血输血输血
流血性休克管理的管理.

背景情况:

关于在严重创伤中早期冷藏血小板输血的安全性和有效性的数据有限.
出血性休克需要及时干预,以改善患者的治疗结果.

研究的目的:

评估早期冷藏血小板输血的可行性,有效性和安全性,与在患有出血性休克患者的标准护理相比.
评估对24小时死亡率和血栓性并发症的影响.

主要方法:

第二期,多中心,随机,开放标签的临床试验,涉及5个美国创伤中心.
患有大规模输血和出血控制手术风险的患者被随机分类.
干预措施:早期输血单个非性冷储血小板单元 (存储≤14天) 与标准护理.

主要成果:

早期冷藏血小板组的24小时死亡率为5.9%,标准治疗组为10.2% (P=0.26).
在辅助结果中没有观察到显著差异.
血栓栓塞和不良事件的发生率在各组之间没有差异.

结论:

在严重受伤的患者中,早期冷藏血小板输血是可行的和安全的.
与标准护理相比,这种输血策略并没有显著降低24小时死亡率.
没有发现血栓并发症或不良事件的风险增加.

Formation of the Platelet Plug

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...
