摘要: 为观察透析过程中不同透析膜对凝血纤溶作用的影响,对12例维持性血液透析患者采用交叉设计,使用铜仿膜和聚砜膜透析器透析,应用ELISA法检测透析过程中凝血酶抗凝血酶Ⅲ复合物(TAT)、纤溶酶α2抗纤溶酶复合物(PAP)、D二聚体的动态变化,并用扫描电镜观察透析后透析器表面凝血情况。结果显示,用2种透析膜血透过程中TAT、PAP、D二聚体均显着高于透析前水平,用铜仿膜透析TAT、PAP、D二聚体均显着高于用聚砜膜。提示,从凝血纤溶激活看,聚砜膜生物相容性好于铜仿膜,长期使用生物相容性好的透析器可能会减少出凝血并发症。

Abstract: To investigate the biocompatibility of dialyzers compared 12 patients on long-term haemodialysis treated with curprophane and polysulphone dialyzers in a cross-over design. During the dialysis TAT, PAP and D-dimer were measured by ELISA. After the dialysis the membranes were observed with scanning electron-microscope. During haemodialysis TAT, PAP and D-dimer with two kinds of dialyzers were higher than before the dialysis. In comparion with cuprophan, concentrations of coagulation and fibrinolysiss parameters in ploysulphone membrane were low. The result indicates that as far as coagulation and fibrinolysis are concerned, the biocompatibility of polysulphone membrane is better than that of the cuprophone one. Biocompatibility dialyzer should be selected to decrease the appearance of the long-term hemodialysis-related complication.
