概括
与限制性策略相比,自由的红细胞输血策略没有改善动脉瘤下关节出血和贫血患者的神经结果. 这两种方法在12个月后在功能独立性和生活质量方面显示出相似的结果.
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:
- 对患有动脉瘤下arachnoid出血 (aSAH) 经历贫血的患者,红细胞输血的最佳策略仍然不清楚.
- 这项研究解决了在aSAH后的重症监护期内围绕自由与限制性输血协议的不确定性.
研究的目的:
- 为了比较自由红细胞输血策略与严格限制策略的有效性,在患有aSAH和贫血的重症患者中.
- 评估输血策略对12个月后神经学结果,功能独立性和生活质量的影响.
主要方法:
- 随机对照试验涉及急性aSAH和贫血的危急病患者.
- 患者被分配到自由输血策略 (血红蛋白≤10 g/dL) 或限制性策略 (血红蛋白≤8 g/dL).
- 主要结局是12个月的不良神经结果 (修改的兰金尺度≥4);次要结局包括功能独立性 (FIM) 和生活质量 (EQ-5D-5L,VAS).
主要成果:
- 在自由 (33.5%) 和限制性 (37.7%) 组之间,在12个月的不良神经结果中没有显著差异 (风险比率0.88;95% CI,0.72至1.09;P=0.22).
- 在两个组中,功能独立 (FIM) 和生活质量 (EQ-5D-5L,VAS) 的平均得分相似.
- 在自由和限制性输血策略组之间,不良事件的发生率相似.
结论:
- 自由的红细胞输血策略不会导致较好的神经学结果相比,限制性策略在患有动脉瘤下关节出血和贫血的患者.
- 输血值≤10g/dL与≤8g/dL并没有显著影响该患者群体的12个月功能或生活质量结果.

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...
