Résumé
Hemodialysis has been used as a replacement therapy in patients with end-stage renal failure for several decades. Insufficient and low efficient hemodialysis increases the mortality rate in the patients. The aim of this study to compare the dialysis adequacy in patient's that referred to Golestan province hemodialysis centers. In this descriptive-comparative study 389 patients that have been underling permanent hemodialysis in eight hemodialysis centers of Golestan province were selected as census sampling method. Demographic date form [7 questions] patient registered dates in dossier according to study purpose [12 questions] were used as date gathering tools. Blood samples obtained before and after hemodialysis. Before starting hemodialysis and five minutes after pump stopping, arterial Blood urea nitrogen [BUN] was measured and then KT/V was calculated according to Daugirdas II formula. Statistical tests such chi-square, one way ANOVA and post hoc Analysis with Scheffe' test were used for data analyses in SPSS 13 environment. Mean of KT/V and URR in the eight hemodialysis centers of Golestan province were 1.33 and 63.22% respectively. Kalaleh hemodialysis center had highest level of KT/V [Mean=1.59] and Aghala hemodialysis center had lowest level of KT/V [Mean=1.03] and this difference was statistically significant [P<0.05]. There was statistically significant correlation between KT/V and hemodialysis time, venous and arterial needle distance, venoarterial needle direction and blood flow rate [P<0.05]. The study showed that, hemodialysis efficacy in this province is near to standard and it could be improved with some considerations such as increasing in hemodialysis time, venous and arterial needle distance and needle distance
