Abstract:
In this study, authors observed and compared the clearances of different molecule weight substances between different dialysis membranes and different hemopurification methods. The results showed that the clearances of BUN by hemodialysis (HD) with cuprophan membrane, hemodiafiltration (HDF) with polysulfone and high flux dialysis (HFD) with polysulfone were all satisfactory. TACurea were all below 50 mg. Hemodialysis with cuprophan could clean out some middle molecule substances (MMS), but not ?2-microglobulin (?2m). Hemodiafiltration with polysulfone had the best clearances of MMS and ?2m. Hemofiltration (HF) with polysulfone had fair clearances of MMS and ?2m, but the clearances of BUN and Cr by HF were not so good. The clearances of MMS and ?2m by high flux dialysis were lower than those of HDF and HF. The clearances of MMS and ?2m by continuous ambulatory peritoneal dialysis (CAPD) at a single time were lower than those of HF, HDF and HFD, but the general clearances of MMS and ?2m by CAPD per week were two to four times higher than those by hemodialysis with cuprophan. CAPD is a choice method for those hospitals where HF or HDF can not be performed.
