[ effect of increasing blood flow rate on complications and dialysis adequacy in hemodialysis patients with low KT/V]

ABSTRACT

Insufficient dialysis, increasing complication, duration of hospitalized and expenditures in end stage renal disease patients. Several factors, including increased blood flow rate in the absence of complications can improve dialysis adequacy. So the aim of this study is to investigate the Effected of increasing blood flow rate on complications and dialysis adequacy in hemodialysis patients with Low KT/V. In this quasi-experimental study ,one group [pre-post test], all 45 hemodialysis patients, at 6 month bygone had 3 times in week, each time 3 to 4 hours of hemodialysis and KT/V was less than 1.2, in two sessions, that in first session adjustment blood flow rate on 230 ml/min and other increased 15% of blood flow rate in patients<65 Kg of body weight and 20% in patients>65 Kg in 2009 By the questionnaire and Check list were studied, and than we control KT/V and complications and finally by the statistical tests such Paird-Samples /-test and McNamara were compared. Mean systolic and diastolic blood pressure, incidence of hypotension, nausea, vomiting, muscle cramp did not have a significant difference within the tow status and the mean KT/V with the before and after increased blood flow rate ,was respectively 0.99 +/- 0.09 and 1.3 +/- 0.12 and results showed significant difference [P=0.001] comments from dialysis adequacy. Although the Complications during hemodialysis, while the two study conditions did not have a significant difference and also increase blood flow rate caused increase dialysis adequacy can be concluded that increased blood flow rate is effective on dialysis adequacy
