[2 1/2-year experience with highly-effective short-term dialyses in Erfurt].

At present 18 of 19 dialysis patients undergo the highly effective short-term dialysis, which is used in the Erfurt centre since November 1974. The therapy is performed by two parallel dialysators C-DAK 4 for 3 to 4 hours (24.4 square metres -- hours/week). During the period of observation of 2 1/2 years altogether 35 patients were treated with the short-term dialysis. There are compared clinical and paraclinical parameters of 12 patients who on an average for 2 years underwent the short-term dialysis. The serum levels of retained substances of protein and albumin as well as the "optimum weight" did not or only unessentially differ from each other. Also the blood pressure values scarcely deviated from each other before and after dialysis. The manifold use of the C-DAK 4 is the cause for an increased substitution of erythrocytes. Insufficient compensation of the circulation and a low body weight are regarded as contraindication to the short-term dialysis.
