EFFECT OF BLOOD FLOW RATE ON DIALYSIS ADEQUACY IN AL-KADHIMIYA TEACHING HOSPITAL

Abstract

Background:Adequacy of dialysis is one of determinants of morbidity and mortality. The Blood flow rate is one of important factors of adequacy of dialysis in patients with Hemodialysis.
Objectives:To assess the effect of blood flow rate on adequacy of dialysis.
Methods:Seventy patients maintained on regular Hemodialysis in the dialysis unit, Al-Kadhimiya Teaching Hospital. Their body weight and blood urea level before and after hemodialysis sessions were recorded, volume of ultra-filtration, duration of dialysis and blood flow rate were documented in a checklist. Both (kt/v) and (URR) were determined at three different pump speed (150-200), (201-250) and (251-300) ml/min. During hemodialysis, the hemodynamic status and vital signs of patients were monitored and controlled.
Results:Efficiency of dialysis was calculated using the standard formulas. Paired t-test showed no significant difference in dialysis efficiency between the three groups.
Conclusion:Higher rate of inadequacy of hemodialysis, and no significant correlation was observed between BFR groups.
Key words: Hemodialysis, Blood flow rate, Adequacy of dialysis
