医源性贫血及其防治研究进展

The research and development of iatrogenic anemia and its prevention

背景长期住院的重症监护室（intensive care unit，ICU）患者大多合并不同程度的贫血。由检查、治疗等措施造成的贫血被称为“医源性贫血”。因医源性贫血常需输血治疗，而异体输血常出现输血相关性副作用，对患者预后产生不利影响。目的了解医源性贫血及其研究进展。内容综述医源性贫血的现状、原因、危害及预防策略。趋向对医源性贫血进行预防性干预，在保证患者原发疾病治疗的基础上最大程度减少异体输血，改善ICU患者的预后。

Backgroud Most patients with long-term hospitalization in intensive care unit （ICU） have the eomorbidity of anemia in varying degrees. Anemia caused by the examination and treatment was referred to as ＂iatrogenic anemia＇. Iatrogenic anemia often requires blood transfusion, but this therapy often have adverse effects associated with blood transfusion, which can results in adverse effect on the prognosis of patients. Objective Understanding the iatrogenic anemia and its reasereh progress. Content The status, causes, harmfulness and prevention strategies of iatrogenic anemia was reviewed. Trend Taking methods to prevent iatrogenic anemia, minimizing allogeneic blood transfusion on the basis of guaranteeing essential treatment in patients and improve the prognosis.
