介绍 多数研究显示,深静脉血栓(DVT)的发病率每年约为1:1000。其发病率的增加与年龄有关。在低分子量肝素(LMWH)应用于该病以前,对静脉血栓治疗传统方法主要是住院用普通肝素(UFH)治疗数日,一般通过静脉输注UFH,以患者APTT值与对照血浆的比值按时做实验室监控。不同患者对肝素所需的剂量 Introduction Most studies show that the incidence of DVT is about 1: 1000 per year. Its incidence increases with age. Before the low molecular weight heparin (LMWH) was applied to the disease, traditional methods of treating venous thromboembolism were primarily hospitalized with unfractionated heparin (UFH) for several days, usually by intravenous infusion of UFH, with the ratio of patient APTT to control plasma being done on time Laboratory monitoring. Different patients need the dose of heparin
