The efficacy of hemodialysis in 36 old pationts with renal failure admitted from Jan 1978 to May 1996was analysed retrospectively and compared with that in 28 randomly selected adult patients in the same period as cohtrol. Before hemodialysis the incidence rate of complications was up to 40%in the aged

of which the cardiovascular complications occured frequently.but inthe abult group.the rate was only 25% After hemodialysis.blood urea nutrogen (BUN)and creatinine (cr) consideally decreased in both groups.Chronic heart failure and metabolic acidosis improved in some degree.Bolld pressures of patients with hypertensiom were remardedly lowered.Although hemodialysis has high risk in the aged

it may avoid most complications caused by peritoneal dialysis and restorewater

electrolytes and acid-base balance

Inelderly payients with real faiture Hemodialysis may improve prognosis and increase the surrival rate of elderly payients with real faiture. Hemodialysis may improve prognosis and increase the surrival rate of elderly patients with renal failure

if we could masted proper indications of hemodialysis and choice good apportunity of treatment ultrafilter rate and output volume of ultrafilter of each dialysis.this method is suitahle to the old patients.
