Erstdialyse-Syndrom

The dialysis disequilibrium syndrome (DDS) is a situation characterized by development of neurological symptoms following the rapid removal of urea during hemodialysis. It develops primarily from an osmotic gradient that develops between the brain and the plasma as a result of rapid haemodialysis. It usually occurs during the last hour of hemodialysis or thereafter. The diagnosis of dialysis disequilibrium syndrome in patients with end stage renal failure is mainly based on exclusion of other possible central nervous system disorders .
