| [ Summary ] |
The evaluation of ultrafiltration failure (UFF) is the most important point in peritoneal dialysis treatment. The definition of UFF in standard PET was defined as a net ultrafiltration of less than 100 ml/4 hr. Modified PET, using 4.25 % dextrose dialysate is necessary for close evaluation. A decrease in dialytic fluid Na (Na sieving) of 5 mEq/l on a modified 1-hr-PET and/or net ultrafiltration volume of less than 400 ml/4 hr can result following UFF, Furthermore, total ultrafiltration volume of less than 500 ml/day using a 2.5% dextrose dialysate 4 times daily proposed by the Japanese SEP study group has become the standard by which to evaluate UFF. In the therapeutic approach, the peritoneal dialysis prescription should be change depending on the peritonial permeability and UFF classification. However, we must resolve whether to use icodextrin alone or to combine it with hemodialysis. |
