国产与进口低分子肝素在血液透析中抗凝作用的比较

Comparison of anticoagulation efficacy and clinical safety between imported and domestically manufactured low-molecular-weight heparin during hemodialysis.

OBJECTIVE: To compare the anticoagulation efficacy and clinical safety of domestically manufactured and imported low-molecular-weight-heparin during hemodialysis. METHODS: Sixty patients on hemodialysis were randomly divided into 2 groups, who received intravascular injections of domestically manufactured or imported low-molecular-weight heparin to prevent coagulation. Active partial thromboplastin time (aPTT), prothrombin time (PT), thrombin time (TT) and factor Xa activity were determined during dialysis. RESULTS: No incidence of major bleeding was encountered in all of these patients. Similarly low incidences of clotting in extracorporeal circuit were found in either group. No significant differences in aPTT, PT, TT and plasma levels of factor Xa were observed between the two groups. CONCLUSION: Low-molecular-weight heparin domestically manufactured is safe and efficient for anticoagulation during hemodialysis as compared with the imported heparin.
