|July 4, 2025
概括
在创伤患者中,超大规模输血 (UMT) 显示不平衡比率的死亡率更高. 增加血小板与红细胞的比率显著降低了UMT患者的死亡率.
科学领域:
- 创伤复苏 创伤复苏
- 血液性冲击管理 血液性冲击管理
- 血液制品输血 输血 血液制品输血
背景情况:
- 新鲜冷血 (FFP),血小板 (PLT) 和红细胞 (RBC) 的1:1:1比率是出血性休克的标准,但基于低体积输血.
- 超大规模输血 (UMT),定义为≥20单位的红细胞产品/24小时,提出了独特的挑战,目前的指南没有完全解决.
研究的目的:
- 研究不同输血比率对接受UMT的创伤患者死亡率的影响.
- 为了确定FFP:RBC和血小板:RBC的特定比率是否会影响UMT中的生存结果.
主要方法:
- 一个多中心的回顾性审查,涉及11个I级创伤中心的1155名患者 (2016-2024年).
- 患者根据FFP:RBC和血小板:RBC比率 (<1:2低, 1:2-1:1中等,≥1:1高) 进行分类.
- 主要结局是死亡率,分析了输血比率作为风险因素.
主要成果:
- 在UMT队列中,整体死亡率为62.9%.
- 较高的血小板:RBC比率与死亡率降低相关:70.8% (低),59.1% (中等) 和47.6% (高).
- 血小板:红血球比率是死亡的独立风险因素 (或0.54中度,或0.39高;P<0.001两者).
结论:
- 这项大型多中心研究表明,在UMT患者中,更平衡的血小板:RBC输血比率显著降低了死亡率.
- 早期和更积极的血小板输血可能会改善UMT的创伤患者的生存率.
- 当前的输血指南可能需要对需要UMT的患者进行重新评估.
