The decision to transfuse a patient is not always clear and straightforward, particularly because no single number, neither extraction ratio nor hemoglobin level, can serve as an absolute indicator of transfusion need. Clinical assessment of the patient in conjunction with physiologic values helps in determining the appropriateness of transfusion before the advent of hypoxia or ischemia. The benefit of transfusion in relation to mortality and morbidity is discussed here based on an assessment of the literature, and transfusion guidelines from several organizations are summarized.
决定给患者输血并不总是清晰明了的，特别是因为没有一个单一的数值，无论是提取率还是血红蛋白水平，能够作为输血需求的绝对指标。在出现缺氧或缺血之前，结合生理值对患者进行临床评估有助于确定输血的适宜性。本文基于对文献的评估讨论了输血在死亡率和发病率方面的益处，并总结了几个组织的输血指南。
