The optimal use of PAN membrane in RDT.

In order to compare the efficiency of PAN (Biospal 3000S) for small molecules, Cr, BUN, UA and Pi clearances were determined during hemodiafiltration with both pre and postdilution fluid (PreHDF, PostHDF) and during biofiltration in 3 regular dialysis treatment patients. The highest clearances were obtained during PostHDF. Therefore, since the small molecules are still considered the most important toxins in chronic renal failure, these findings indicate that optimal use of PAN is with PostHDF, in which high diffusion and convection are combined, in order to obtain best dialytic efficiency.
