概括

与限制性方法相比,自由输血策略可能会改善创伤性脑损伤 (TBI) 患者的神经结果. 然而,自由主义策略与急性呼吸困扰综合征增加和血液产品使用量增加有关.

科学领域:

关键护理医学关键护理医学
神经学神经学
输血医学输血医学

背景情况:

创伤性脑损伤 (TBI) 管理需要平衡氧气需求,神经恢复和输血相关并发症.
在TBI患者中,在自由和限制性输血策略之间做出选择是一个临床挑战.

研究的目的:

在TBI患者中,比较自由与限制性输血策略的有效性和安全性.
在TBI中提供有关输血值的临床指导方针.

主要方法:

进行了随机对照试验 (RCT) 的系统审查和元分析.
搜索电子数据库从创立到2024年10月.
包括5个RCT,涉及1533名TBI患者.

主要成果:

在自由和限制性输血组之间,在有利的格拉斯哥结论量得分,医院死亡率或感染率方面没有观察到显著差异.
自由输血组的急性呼吸窘迫综合征发病率较高,并且每名患者接受的血液单位更多.
在住院或重症监护室停留时间方面没有发现显著差异.

结论:

自由的输血策略可能与TBI患者的神经结果的改善有关.
需要进一步的研究来评估并发症概况和特定血红蛋白值 (例如,9 g/dL) 的影响.
目前的指导方针可能会从修订中受益,以考虑在TBI中输血的9g/dL门.

Blood Transfusion and Agglutination

Blood Transfusion and Agglutination

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...
