Objective To study the solute clearance effect of t he new concentrated anticoagulation hemodialysate of citrate for hemodialysis in patients with high risk of bleeding.Methods During the period of 2002-06~2003-12,42 patients with h igh risk of bleeding were divided into two groups according to hemodialysis mann ers.Group Ⅱ were hemodialyzed with new citrate anticoagulation hemodialysate wi thout any other anticoagulant and group Ⅰ were hemodialyzed with bicarbonate he modialysate with dalteparin anticoagulation.The BUN and Cr levels were determine d before and after dialysis and Kt/V and URR were calculated.In addition,ACT and iCa 2+ were also measured at the artery and venous end.Results ACT was extended and iCa 2+ decreased significantl y at the venous end compared with that at the artery end in group Ⅱ (P0.05).Conclusion The solute clearance effect of the new concentrated anticoagulation hemodialysate of citrate for hemodialysis in patients with high risk of bleeding is excellent.

Objective To study the solute clearance effect of the new concentrated anticoagulation hemodiaiysate of citrate for hemodialysis in patients with high risk of bleeding. Methods Forty-two kidney failure patients with high risk of bleeding were divided into two groups (Group A and Group B) according to their hemodialysis manners. Patients in Group A were hemodialyzed with bicarbonate hemodialysate with low-molecular-weight heparin (dalteparin) anticoognlation and those in Group B with the new citrate antieoagnlation hemodialysate prepared in our hospital without any other anticoagulant. Blood urea nitrogen (BUN) and creatinine (Cr) concentrations were measured before and after dialysis, and Kt/V and urea reduction rate (URR) were calculated. In addition, activated clotting time (ACT) and ionized calcium (iCa2+) concentration were also measured at the arterial and venous ends. Results ACT was extended and iCa2+ concentration decreased significantly at the venous end compared with those at the arterial end in Group B (P<0.01). BUN and Cr concentrations were markedly decreased after dialysis compared with those before dialysis in both groups (P<0.01), and no significant difference in solute clearance effect, as indicated by Kt/V and URR, was observed between Group A and Group B (P>0.05). Conclusion The solute clearance effect of the new concentrated anticoagnlation hemodialysate of citrate is excellent during hemodiaiysis in kidney failure patients with high risk of bleeding.
