一个全州的回顾性队列研究,检查在血管外科患者中输血旧血液产品的影响
Journal of vascular research
|August 28, 2025
概括
在血管疾病患者中,输血较老的红细胞和血小板并没有增加死亡率. 较老的血液制品与更少的输血单位和更短的住院时间有关.
科学领域:
- 输血医学
- 血液学
- 血管外科
背景情况:
- 血液制品的年龄是输血有效性的关键因素.
- 较古老的血液制品,特别是红细胞 (PRBC) 和血小板 (PLT),通常可供使用,但它们对患者的结果的影响仍在争论中.
- 血管外科手术患者是一个独特的群体,有特殊的输血需求.
研究的目的:
- 研究老年红细胞和血小板输血对血管外科手术患者的死亡率,停留时间和血液产品利用的影响.
- 为了比较接受新鲜 (< 21 天PRBCs, ≤ 3 天PLTs) 与接受旧 (≥ 35 天PRBCs, > 3 天PLTs) 血液产品的患者的结果.
主要方法:
- 在昆士兰州 (2007-2013) 接受无心肺旁路手术的血管患者中,对PRBC和PLT输血进行了回顾性分析.
- 接受新鲜PRBC和PLT组之间的死亡率,停留时间 (LOS) 和血液产品数量的比较.
- 统计分析包括几率比率 (OR) 和95%的置信区间 (CI).
主要成果:
- 在接受旧PRBC与新鲜PRBC (3. 9%与5. 3%;或0. 75) 或旧PLT与新鲜PLT (17. 9%与19. 4%;或1. 0) 输血的患者之间没有显著的死亡率差异.
- 与接受新鲜PRBC的患者相比,接受旧PRBC的患者停留时间较短 (10天 vs 11天),需要较少的PRBC单位 (2.1个 vs 3. 9个单位).
- 在血小板输血中,没有根据年龄发现死亡率或LOS的显著差异.
结论:
- 在血管外科手术患者中,输血旧的PRBC和PLT并没有增加死亡率.
- 使用较旧的血液制品可能导致血液制品的使用量减少和住院时间缩短.
- 需要进一步的前性研究来证实这些发现并优化血液制品管理策略.

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
