摘 要:预防性血小板输注是指通过输注血小板使各种血小板生成障碍患者,如恶性血液病、再生障碍性贫血(aplastic anemia,AA)、骨髓移植等患者的血小板计数(platelet count,PLT)提高到某一安全水平,达到防止出血的目的〔1〕。欧美国家超过70%的血小板输注为预防性输注,根据AABB的调查〔2〕,60%的医疗机构以PLT值20×109/L作为预防性输注的临界值。When platelet count falls below a certain threshold,the risk of bleeding will be significantly increased in patients with hematological diseases.In these patients,prophylactic platelet transfusion is an important measure to prevent intracranial hemorrhage.However,repeated apheresis platelet transfusion may lead to invalid transfusion.And platelet is a limited resource and very expensive.So domestic and foreign studies suggest that "platelet count lower than 20×109/L" is no longer a golden standard for platelet transfusion.Due to the different mechanisms of bleeding in aplastic anemia,primary immune thrombocytopenia,acute myelocytic leukemia,myelodysplastic syndrome,malignant lymphoma and other blood diseases,the tolerance of patents in low level of platelets is different.Further studies should be done to set platelet transfusion thresholds for various types of blood diseases.
