[Clinical chemistry parameters in continuous peritoneal dialysis].

The continuous peritoneal dialysis (CAPD) is with four or five change of 1 1/2-2 l dialysis solution a day a 24 hours/day and 7 days/week dialysis. In 6 patients with terminal renal insufficiency the behaviour of biochemical parameters which serve as acknowledged indicators for the efficiency of a dialysis technique, were pursued under this method more than 4 weeks. At the end of the treatment period the following average values came up: creatinine 9.0 mg/dl, urea-N 65 mg/dl, anorganic phosphate 4.8 mg/dl (without Al-hydroxide), potassium 4.3 mval/l, calcium 4.1 mval/l and a pH-value of 7.35. The results allow the conclusion that with the CAPD a sufficient elimination of retention products is possible and values in the suburaemic region may be achieved similar to the conditions in the intermittent dialytic technique. Conclusions concerning a broad application of the technique in the terminal renal insufficiency may, however, not be made alone from these observations, since the problems of relapsing peritonitis and of the chronic loss of protein known from literature did not yet play a role in our patients in the short observation period.
