[Urea-oriented dialysis management in routine care]

An approximation variant of the 1-compartment model and its clinical application in routine work are described. It is demonstrated how quantity and distribution of the dialyses, clearance and duration of the dialysis are to be chosen in order to obtain in a patient a course of the urea concentration striven for. A probable residual dialysis is taken into consideration. By this means an adaptation of the management of dialysis to the protein balance of the patient and to the effect of the dialysis with regard to easily dialysable substances is possible. The system demonstrated stood the test in clinical routine work. It is simple in its application, since the connections can be brought in easily legible graphs. Decisions in practice on duration of the dialysis, type of dialyzer and frequency of dialysis get a quantifiable basis.
