Objective: In this study, we initiated a new hemodialysate with citrate buffer, observed the factors that influence the citrate concentration of solution in hollow fibers when using citrate hemodialysate, and observed the anticoagulant effect and safety of the citrate hemodialysate in the experiment in dogs. Methods: Ten dogs were given intermittent hemodialysis and were divided into 3 groups according to hemodialysis procedures. Group 1 was saline‐flush hemodialysed with bicarbonate hemodialysate; Group 2 was hemodialysed with citrate hemodialysis without any anticoagulant; Group 3 was hemodialysed with bicarbonate hemodialysate and heparin. ACT, Ca ++ , BUN, Cr, ALT, AST, TBIL, DBIL, Na + , Cl − , , and venous pressure were monitored in the animals of each group during hemodialysis. Results: During the hemodialysis in Group 1, venous pressure increased lastingly, resulting in the failure of hemodialysis for 2 hours. Hemodialysis for 2 hours in Group 2 were all finished successfully. ACT was extended and Ca ++ decreased obviously in the venous end during hemodialysis. And ALT, AST, Ca ++ , K + , Na + , Cl − , after the hemodialysis in Group 2 were not changed (P > 0.05). Moreover, the clearance rate of the dialyzers with citrate dialysate increased significantly compared with those of saline‐flush and heparin anticoagulation. Conclusions: The anticoagulant and dialytic effects of the new type citrate hemodialysis are satisfactory and better than that of saline‐flush.
