概括
自由的红细胞输血策略显著减少了急性脑损伤和贫血患者的不良神经结果. 与限制性输血方法相比,这种方法也可以提高良好的康复机会.
科学领域:
- 神经学 神经学
- 关键护理医学 关键护理医学
- 血液学 血液学 血液学
背景情况:
- 贫血常见于急性获得性脑损伤 (ABI) 的患者.
- 输血策略,自由与限制,旨在管理贫血及其后果.
- 这些策略对长期神经功能的影响需要评估.
研究的目的:
- 为了比较自由 (血红蛋白触发 ≤90-100 g/L) 与限制性 (血红蛋白触发 ≤70-80 g/L) 红细胞输血策略.
- 评估对急性ABI和贫血的成年患者长期神经功能结果的影响.
- 评估二次结果,包括严重残疾,良好的康复和不良事件.
主要方法:
- 随机对照试验 (RCT) 的系统审查和研究水平的元分析.
- 在 MEDLINE,EMBASE 和 Cochrane 数据库中进行了搜索.
- 包括RCT比较自由与限制性输血在急性ABI和贫血 (血红蛋白≤100 g/L) 的成年患者. 主要结局:不良的神经结果 (格拉斯哥结局量表或修改的兰金量表). 使用GRADE方法评估证据的确定性.
主要成果:
- 分析了5项涉及2364名患者的试验.
- 自由输血显著降低了不良神经结果的风险 (风险比率[RR]=0.89,95% CI 0.84至0.95;高确定性).
- 自由输血可以减少严重残疾 (RR=0.82,95% CI 0.66到1.02;中度确定性) 并可能增加良好的康复 (RR=1.29,95% CI 0.95到1.76;低确定性). 没有观察到死亡或大多数不良事件的显著差异. 神经学结果的统计异质性较低 (I2=0%-36%).
结论:
- 在急性ABI和贫血的成年人中,自由的红细胞输血策略与不良神经结果的风险降低有关.
- 这种策略也可以提高实现良好的功能恢复的可能性.
- 这些发现支持对这一患者群体采取自由的输血方法,以减少不良结果的高度确定性.

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...
