血液透析治疗急性肾衰已被公认。但当合并出血危险的患者，应用普通肝素（SH）抗凝，会加重出血，导致不良后果。以往对这些患者的抗凝是采用小剂量或无肝素透析，但常常因为凝血而导致治疗失败。为此，我fi’1探索应用低分子量肝素（LMWH）抗凝进行血液透析治疗急性肾衰合并出 Hemodialysis for acute renal failure has been recognized. However, when combined with bleeding risk in patients with unfractionated heparin (SH) anticoagulation, will exacerbate bleeding, leading to adverse consequences. In the past, anticoagulation was performed on these patients using low-dose or no-heparin dialysis, but treatment failure often resulted from coagulation. To this end, I fi’1 explore the application of low molecular weight heparin (LMWH) anticoagulation for hemodialysis in acute renal failure combined with
