红细胞 (RBC) 输血在败血症复苏中很常见. 虽然对整体死亡率没有影响,但血红蛋白水平超过10g/dL的输血可能会增加危险的危险病患者.
科学领域:
- 关键护理医学 关键护理医学
- 血液学 血液学 血液学
- 输血医学 输血医学
背景情况:
- 红细胞 (RBC) 输血经常在早期败血症复苏期间进行.
- 红细胞输血治疗败血症的现有临床实践可能与现有的基于证据的指导方针不一致.
研究的目的:
- 在早期败血症复苏中调查现实世界红细胞输血模式.
- 确定早期红细胞输血与败血症患者60天死亡率之间的关联.
主要方法:
- 一个潜在的,多中心的观察队列 (韩国败血症联盟) 的二次分析,包括2613名患有败血症的成年ICU患者.
- 根据在ICU前三天内输血RBC的情况,患者被分为输血和不输血组.
- 倾向性得分匹配用于控制混因素.
主要成果:
- 45.3%的败血症患者在早期复苏期间接受了红细胞输血,常常血红蛋白水平高于10g/dL.
- 红细胞输血与血红蛋白以外的临床因素有关,包括较高的疾病严重程度得分和器官功能障碍.
- 在倾向分数匹配分析中,没有观察到60天死亡率的整体差异. 然而,一个显著的相互作用表明,在血红蛋白≥10 g/dL的输血中,死亡率更高,并且在<10 g/dL时死亡率下降的趋势.
结论:
- 红细胞输血在重症败血症患者中很普遍,这表明与指导方针建议的差异.
- 虽然整体死亡率没有受到影响,但血红蛋白值为10 g/dL至关重要.
- 输血在10g/dL以下可能有益,但在血红蛋白水平为10g/dL或更高时应避免输血,以防止潜在的伤害.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
