贫血在ICU内危重患者中较普遍,可因各种类型的显、隐性失血及红细胞生成减少等引起。针对病因预防,实行严格的输血指征,可减少患者输血相关性肺损伤、免疫功能抑制及感染性并发症等风险,并有助于改善患者预后。通过使用重组人红细胞生成素(rh-EPO)可能是减少ICU内输血的有效策略。 Anemia is more common in critically ill patients in the ICU and can be caused by various types of manifest, occult blood loss and reduced erythropoiesis. For etiological prevention, the implementation of strict transfusion indications can reduce the risk of transfusion-related lung injury, immune suppression and infectious complications in patients with and help to improve the prognosis of patients. By using recombinant human erythropoietin (rh-EPO) it may be an effective strategy to reduce blood transfusions within the ICU.
