dialysis disequilibrium syndrome

di·al·y·sis dis·e·qui·lib·ri·um syn·drome

nausea, vomiting, and hypertension, occasionally with convulsions, developing within several hours after starting hemodialysis for renal failure; apparently caused by too rapid removal of urea from the extracellular fluid compartment, with movement of water into cells, and cerebral edema.
