概括
癌症患者的贫血可能需要输血红细胞. 像氧气提取比率 (O2ER) 这样的生理触发器提供了比单独的血红蛋白更好的个性化输血策略.
科学领域:
- 在瘤学瘤学.
- 血液学 血液学 血液学
- 关键护理医学 关键护理医学
背景情况:
- 贫血常见于癌症患者,通常用红细胞输血治疗.
- 目前的输血指南主要使用血红蛋白水平,这可能不完全反映氧气输送.
- 物理参数,例如氧气提取比率 (O2ER),可以实现更个性化的输血决策.
研究的目的:
- 调查氧气提取比率 (O2ER) 是否可以预测贫血瘤患者对红细胞输血的反应.
- 为了比较生理触发剂与血红蛋白水平在指导输血策略中的有效性.
主要方法:
- 一项前性观察性研究包括107名稳定的成年瘤患者,需要输血红细胞.
- 患者根据基线O2ER (≤35.4%或>35.4%) 进行了分层.
- 输血前后测量了O2ER,ScvO2,PvO2,A-V O2diff,乳酸和 ΔCO2 的变化.
主要成果:
- 基线O2ER较高 (>35.4%) 的患者在输血后的氧化参数中比O2ER较低的患者有更大的改善.
- 基线O2ER与PvO2,ScvO2,A-V O2diff,ΔCO2和乳酸的变化有显著的相关性.
- 血红蛋白水平与生理反应的相关性有限,与O2ER不同.
结论:
- 仅仅血红蛋白水平可能不足以评估稳定的贫血癌症患者的氧气供应状况.
- 氧气提取比率 (O2ER) 和其他生理触发因素为优化输血策略提供了宝贵的信息.
- 以生理参数为指导的个性化输血方法需要在更大的试验中进行进一步的研究.

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...
