Abstract:
Objective To explore the effects of intra-jugular vein dual lumen catheter lock heparin in different concentrations on the coagulation function,hemorrhagic tendency and catheter thrombosis risk in hemodialysis patients,and to investigate the reasonable lock heparin cuncentration. Method Ninety end stage renal disease (ESRD)patients receiving regular hemodialysis were enrolled and randomly assigned into 3 groups(n=30):Group A(pure heparin lock solution,6250 U/m1),GrouP B(medium heparin lock solution,1040 U/ml)and Group C(low hepafin lock solution,625 U/ml).The coagulation indexes were determined in short term.Complications such as bleeding,thrombosis,infection and thrombocytopenia were monitored.Results Prothrombin time(PT),actiwtted partial thromboplastin time(APTT)and thrombin time (TT)were significantly prolonged in Group A(P＜0.01);only APTT was signifieanlly prolonged in Group B:however,no significant changes were observed in Group C.Hemorrhage risk was much higher in Group A than that in Group B and C (26.7%vs 10%and 0.P＜0.05).Catheter thrombosis incidence was significantly higher in Group C than that in Group A and B(23.3%vs 0and 10%,P＜0.05).Only 1 suspected catheter related infection was found in Group C,and 2cases of moderated thrombocytopenia in Group A. Concltrsion Moderate concentration of lock heparin solution has the best balance of hemorrhagic and thrombotic risk,and should be recommended to most of regular hemodialysis patients.
