Factors affecting the concentration of citrate solution in dialyzers when using citrate hemodialysate in vitro |
| |
Abstract: | Objective To observe the factors that affect the concentration of citrate solution in hollow fiber when using citrate hemodialysate. Methods By modeling hemodialysis in vitro, we used 6 types of hemodizlyzers, different blood flow rates , different dialysate flow-rates and different fluids instead of blood to hemodialyses in vitro to detect the citrate concentration in hollow fiber.Results The citrate concentrations in different hemodialyzers were F60>FB130UGA>GA HP130>F6>FB 130AGA>WS 70. The concentrations at different dialysate flow rates were 500?mL·min -1 >250?mL·min -1 . The concentrations at different blood flow rates were 100?mL·min -1 >200?mL·min -1 .Conclusion The concentration of citrate solution in hollow fiber is affected by different types of hemodialyzers and different bloods as well as dialysate flow rates . To achieve anticoagulation when using hemodialysate, we must select suitable hemodialyzer such as FB 130UGA. |
