病人输注血液、血液成分或血液制品导致任何不良反应都归类为输血反应。实验室常称为输血反应,严格地说这一名称并不正确,因为输血“反应”可以是有益的或者是有害的。输血反应的分类方法错综复杂,一般可分为溶血性反应、非溶血性反应、疾病的传播和其他并发症。由于输血法规不健全,输血反应的发生率,国内尚无确切的报道。 Patients with blood, blood components or blood products lead to any adverse reactions are classified as transfusion reactions. Laboratory often referred to as transfusion reaction, strictly speaking, the name is not correct, because blood transfusion “reaction” can be beneficial or harmful. The classification of transfusion reactions is complex, generally divided into hemolytic reaction, non-hemolytic reaction, the spread of the disease and other complications. As the blood transfusion regulations are not perfect, the incidence of transfusion reactions, there is no exact report.
