Abstract
The improvement in hemodialysis (HD) treatment has been done, but the recent treatment is not necessarily perfect. WADIC is now being developed in our laboratory to treat each chronic renal failure patient satisfactorily. WADIC can measure the concentrations of urea nitrogen (UN), creatinine and MM in outlet dialysate. Integration of outlet dialysate concentration (CD) during the treatment will give the total amount of removed solute (M). UN and creatinine concentration in blood may be estimated from CD by using the principle of mass balance. In our WADIC system, the remove amount of water (ΔVT) may be controlled just by the change of transmembrane pressure. WADIC can can also control the treatment time and select the suitable type of dialyzer for each patient by following up CB, ΔVT and M all through HD treatments.
