摘要：

【摘要】目的 研究血液透析应用低分子量肝素和普通肝素抗凝时相关实验参数的变化。方法 22例血液透析的尿毒症患者分别用低分子量肝素和普通肝素抗凝，监测指标包括抗因子Xa活性(AFXa )、凝血酶时间(TT)和活化部分凝血活酶时间(APTT)。结果 应用低分子量肝素抗凝时APTT、TT在透析过程中延长不明显（P>0.05），普通肝素组APTT、TT于透析30分钟及透析结束时明显延长，甚至部分血液不凝。血浆抗FXa活性低分子量肝素组透析结束时较透析前有显著性差异，且透析后30分钟及透析结束时均明显高于普通肝素组（P<0.001）。结论 低分子量肝素抗凝作用同APTT、TT无一定相关，低分子量肝素抗凝作用可由抗-FXa水平作为可靠根据，低分子量肝素在血液透析抗凝过程中比普通肝素更为安全、有效。

Abstract: 【Abstract】Objective To study the laboratory parameter of low molecular weight heprin (LMWH) and unfractionated heparin (UFH) in hemodialysis. Methods 22 patients with chronic renal failure were given LMWH and UFM anticoagulanition separately. Detection and comparison the AFXa. thrombin time (TT) and activated partial thromboplastin time (APTT) of these two kinds of anticoagulanition. Results The APTT and TT in LMWH group do not prolong significantly in hemodialysis, while they prolong significantly in UFH group at 30 minutes after hemodialysis and at the end of hemo diylsis. The value of AFXa in LMWH group has significant difference between before and in hemodialysis, and it is significantly higher in hemodialysis than UFH group. Conclusion LMWH anticoagulanition has no effect on APTT and TT,but it has the effect on AFXa. LMWH anticoagulanition has more effecacy and safety in hemodialysis than UFH.
