概括
在大规模输血 (MT) 期间输入ABO不兼容的新鲜冷血 (FFP) 并没有与大型队列研究中增加住院死亡率有关. 这一发现支持在AB FFP无法使用时使用ABO不兼容的FFP.
科学领域:
- 输血医学 输血医学
- 血液学 血液学 血液学
- 关键的护理关键的护理
背景情况:
- 大规模输血 (MT) 协议通常涉及ABO不兼容的新鲜冷血 (FFP),以保护AB FFP库存.
- 关于ABO不兼容的FFP在非创伤性关键出血中的安全性的证据有限.
- 这项研究调查了在MT期间与ABO不相容的FFP相关的患者特征和结果.
研究的目的:
- 为了比较在MT期间接受ABO兼容和ABO不兼容的FPF的患者特征.
- 评估ABO不兼容的FFP输血对MT发作中的住院死亡率的影响.
- 确定在接受MT的患者中与住院死亡率相关的因素.
主要方法:
- 澳大利亚和新西兰大规模输血注册表的回顾性分析 (2011年4月至2018年10月).
- 纳入标准:年龄≥18岁的患者接受MT (4小时内≥5个红细胞单位).
- 不兼容的FFP定义为在MT启动后24小时内≥1个ABO不匹配的单位.
主要成果:
- 包括7340名患者;77人 (1%) 接受了不兼容的FFP (51人没有创伤).
- 接受不兼容FFP的患者获得了更多的FFP单位 (中位数为7对5).
- 不相容的FFP与住院死亡率没有独立相关 (HR 1.40; p=0.2).
- 增加的FFP体积,年龄,并发症评分,低纤维素素和低pH与死亡率有关.
结论:
- 在MT期间输血ABO不兼容的FFP并没有独立地与该队列的住院死亡率增加有关.
- 接受不兼容FFP的患者数量很少,因此需要谨慎解释.
- 结果表明,当AB FFP稀缺时,可以考虑在MT中考虑ABO不兼容的FFP.

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...

The ABO Blood Group
1.5K
The ABO blood group system is a critical element of transfusion medicine, essential for determining blood compatibility in transfusions and organ transplants. It is based on specific antigens, or agglutinogens, present on the surface of red blood cells (RBCs) and corresponding antibodies, or agglutinins, in the blood plasma.
Antigens in the ABO Blood Group System
Antigens are substances that can trigger an immune response, leading to the production of antibodies. In the ABO blood group system,...
