科学领域:

  • 创伤复苏的复苏治疗方法
  • 流血性休克管理的管理.
  • 血液产品的利用 血液产品的利用

背景情况:

  • 超大规模输血 (UMT) 用于创伤患者在出血性休克.
  • 目前还没有UMT的标准化定义.
  • 这次系统性审查的目的是建立UMT的共识定义.

研究的目的:

  • 确定超大规模输血 (UMT) 的共识定义.
  • 确定与接受UMT的患者死亡率增加相关的参数.

主要方法:

  • 对从1979年到2022年的研究进行系统审查.
  • 根据PICO问题和PRISMA指南对文章进行选.
  • 从符合条件的研究中提取数据,定义UMT和结果.

主要成果:

  • 为了提取数据,包括了8项研究.
  • 只有两项研究提出了共识定义:24小时内≥20个红细胞单位.
  • 较低的血压,脉,格拉斯哥昏迷评分,较高的伤害严重性评分和复苏性胸切除术与死亡率增加相关.

结论:

  • 由于缺乏标准化的UMT定义,这带来了临床,研究和伦理方面的挑战.
  • 在24小时内将UMT标准化为≥20个红细胞单位是可行的.
  • 这种标准化可以提高临床护理,研究的一致性,以及创伤管理中的伦理考虑.
