Anemia is common in the intensive care unit, and may be associated with adverse consequences. However, current options for correcting anemia are not without problems and presently lack convincing efficacy for improving survival in critically ill patients. In this article we review normal red blood cell physiology; etiologies of anemia in the intensive care unit; its association with adverse outcomes; and the risks, benefits, and efficacy of various management strategies, including blood transfusion, erythropoietin, blood substitutes, iron therapy, and minimization of diagnostic phlebotomy.
贫血在重症监护病房中很常见,可能与不良后果有关。然而,目前纠正贫血的方法并非没有问题,并且目前缺乏令人信服的疗效来改善重症患者的生存。本文综述了正常红细胞生理学;重症监护病房贫血的病因;与不良结局的关系;以及各种管理策略的风险、益处和疗效,包括输血、促红细胞生成素、血液替代品、铁剂治疗和减少诊断性采血。
