白血病作为一种常见的血液系统恶性肿瘤,在化疗过程中极易发生出血,预防性血小板输注是白血病治疗期间预防出血风险的必要措施[1]。但近年来国内血源紧张、高昂的输血费用及输血风险的存在使得血小板输注时机及剂量的选择尤为重要。有研究表明,低剂量血小板预防性输注对白血病患者预防出血风险的临床效果较好[2]。本研究通过

However, in recent years, the shortage of blood supply, high blood transfusion costs and the risk of blood transfusions make the selection of timing and dosage of platelet transfusion more important. Studies have shown that low-dose prophylactic prophylaxis of leukemia in patients with leukemia prevention of bleeding risk of clinical effect is better [2]. The study passed
