The epidemiology of red cell transfusion is changing. Surgical use has decreased due to reduced transfusion triggers and better operative techniques. Medical use increases partly due to the increasing age of the population. The evidence for and against transfusion at different levels of anaemia is discussed. The appropriate level of haemoglobin at which to recommend transfusion depends on the indication for transfusion, the patient's co-morbidities and the quality of the red cells available.
红细胞输血的流行病学正在发生变化。由于输血阈值降低和手术技术改进，手术用血量有所减少。医疗用血量增加部分原因是人口老龄化。本文讨论了不同贫血水平下支持和反对输血的证据。推荐输血的合适血红蛋白水平取决于输血指征、患者的合并症以及可用红细胞的质量。
