目的:调查我院血液病患者预防性血小板输注阈值的依从性,并探讨血小板输注在更高阈值中使用的原因。方法:本研究调查了230例患者438次临床血小板输注事件,观察了将血小板计数10×109/L设定为阈值时的输注依从性情况,分析了血小板输注在更高阈值水平使用的原因。结果:82.2%的血小板输注严格遵循了输注阈值,96.3%的输注前血小板计数≤20×109/L。输注前血小板计数>20×109/L,其非依从性原因通常为出血。结论:绝大多数血小板输注严格遵循了血小板计数为10×109/L的输注阈值,在危险因素存在的情况下,输注阈值则相应提高。
Objective: To investigate the compliance of prophylactic platelet transfusion threshold in patients with hematological diseases in our hospital and to explore the reasons for the use of platelet transfusion in higher thresholds. METHODS: This study investigated 438 clinical platelet transfusion events in 230 patients and observed compliance with transfusion at a platelet count of 10 × 109 / L as a threshold and analyzed platelet transfusion at a higher threshold level s reason. Results: 82.2% of platelet transfusion strictly followed the infusion threshold, 96.3% of pre-infusion platelet count ≤20 × 109 / L. Pre-infusion platelet count> 20 × 109 / L, the non-compliance is usually the cause of bleeding. CONCLUSION: The vast majority of platelet transfusions strictly followed the infusion threshold with a platelet count of 10 × 109 / L, with a corresponding increase in the infusion threshold in the presence of risk factors.
