Background & Objectives: hyperphosphatemia and hyperkalemia have major roles of mortality and morbidity in hemodialysis patients. In this study we evaluated the effectiveness of increase in blood flow rate on blood potassium and phosphate of hemodialysis patients.
Methods: This is a clinical trial study 42 patients were assessed during the hemodialysis. A questionnaire and laboratory tests were used for gathering data. At first questionnaire of demographic data was completed and then the weight of patients was connected to each session of dialysis. Then the patient was connected to dialysis machine and blood sample was gathered before dialyzer. After taking blood sample, flow rate was regulated on 200 ml/min in the first session and on 250 ml/min in the next session. During hemodialysis, hemodynamic status and clinical status of patients was controlled. At the end of hemodialysis and before disconnection patient from dialysis machine, a blood sample was taken from arterial set before dialyzer (4 blood samples for each patient). Blood sample was sent to laboratory and all of them were analyzed by one technician and with one set.
Results: Average phosphorus changed significantly from 3.35 to 2.94 with increasing Qb from 200 to 250 similar to the increase in Qb in potassium removal (from 3.43 to 3.52) meq/lit. Paired t-test (p0.005).
Conclusion: It can be concluded so that increase in blood flow rate from 200ml/min to 250ml/min, can affect removal phosphorus but can not affect removal of potassium
Keywords: blood flow rates, phosphure, potassium, hemodialysis
