Background & Objectives: Haemodialysis has been used as a replacement therapy in patients with end- stage renal failure for several decades. But it is not clear yet how much haemodialysis a uremic patient needs? ‏ There are different methods for the assessment of needs and adequacy of dialysis. One of these methods was measurement of KT/V of haemodiolytic patients. The aim of this study was to determine dialysis adequacy of haemodialytic patients in Ardabil dialysis center .

  Methods: In this descriptive study, all of the hemodialytic patients (70 cases) in 2002 were studied. Urea and blood cells were determined in the patients' blood samples both before and after dialysis. KT/V methods were used to determine the adequacy of dialysis. The data were collected and analyzed by SPSS software using descriptive (mean,standard deviation) and analytical (X²) statistics.

  Results: The findings showed that KT/V was smaller than 1.2 in 90% of cases. 54.3% of patients were dialysed three times a week mean of dialysis duration was 2.4 ± 1.63 years. Mean of hemoglobin was 8.27 ± 1.69 gr/dl. There was no significant relationship between dialysis adeqnacy and instrument type.

  Conclusion: 90% of haemodialytic patients in this center did not have adaquate dialysis in terms of KT/V criteria. As a result it seems necessery to pay more attention in order to improve the present condition.
