[Hemodynamic aspects of bicarbonate dialysis].

About the comparison of the acetate haemodialysis with the bicarbonate haemodialysis different and partly contradictory data are found in literature. In general the bicarbonate haemodialysis is regarded as that variant of therapy which has a less negative influence on the haemodynamics during the dialysis treatment. On 21 patients comparative examinations were performed with the two variants of therapy. The acute complications during the treatment were registered, the circulatory parameters blood pressure, pulse rate and cardiac output (1/min) were measured and the oxygen partial pressure was established. Comparing the two methods of therapy, no essential differences could be found. Patients with evident acetate incompatibility showed significantly more frequently clinical complications under the acetate dialysis. In the acetate dialysis the oxygen partial pressure clearly decreased which is to be discussed as cause for the circulatory instability in this therapeutic method.
