Factors Associated with Haemodialysis Adequacy ill Patients under Hemodialysis

Delivered dialysis dose measured as KLlV is widely accepted as an important [actor affecting mortality on haemodialysis. It is currently measured relatively infrequently In most units for pragmatic reasons. The current study was designed firstly to determine delivered dose uf dialysis, and secondly to determine what factor lead to failure (0 deliver dose of dialysis in patients with ESRD. Materials and Methods: This descriptive. cross-sectional study was performed in 2005 on 4g patients, in Dialysis Center at Imam rezu Hospital of Mashhad University of Medical Sciences. DKl/V was measured and based on results, patients divideded into two groups of dKIfV >= 102 and dKlIV < 1.2. Access recirculation (AR), hemodynarmc instability, weekly erytropoientin dose, negauve pressure, venues pressure, urea distribution and prescribed KLlV results recorded and analyzed by descriptive statistics and SPSS. Results: Nineteen patients (39.6%) were male and 29 patients (60.4 %) were lema!ʹ The mcan kt/v was I.OS±O.36. Out of 41\ patients, in 19 cases (39.6%) dKl/V was more than 1.2 aud in 29 cases (60.4%) dKlIV was equal or less than 1.2. But mean pKlIV in two groups showed significant difference. The mean pKlIV was1.22±0.25 and 1.44±O.25 in groups of dKlIV :S 1.2 and dKlIV >1.2, respectively (r = 0.03). CoII elusion: Low dialysis prescription, patient-related factors (i.e, hypotension, intradialyric symptoms) and technical factors (i.e access recirculation, negative pre arterial pressure) are main barriers [0 dialysis delivery. But among the above mentioned factors, low dialysis prescription is the most important and appreciated factor.
