Effect of flow adjustment dialysate (Qd) hemodialysis on effectiveness of underweight patients

KDOQI guidelines in 2006 using standard dialysis adequacy Kt/V, where V is volume of distributionof urea, underweight patients have lower total body water, lower V, which couldreduce the requirement without affecting Qd the efficiency of dialysis. Objective: to evaluatethe effect on the adequacy of dialysis Qd reduction occurs in patients weighing less than orequal to 60 kg who are on hemodialysis. Methodology: patients with chronic kidney diseaseon hemodialysis regularly with weight less than or equal to 60 kg of a renal clinic to evaluatetwo periods I and II, were continued therapy parameters with decrease of Qd for the secondperiod. The variables were collected directly by the researchers of the history. The values thusobtained would be compared using t test or paired variables, and statistical significance of thetest below 0,05. Results: we included 61 patients, 60.7% female, mean age 57,3 years (SD 14,8).Average age of men 60.1 (SD 13,9) and women was 55,9 (SD 15,4). There were no statisticallysignificant differences for the variables Kt/V, Hemoglobin and there was a significant reductionin the phosphorus levels. Conclusions: this study demonstrates that adequate therapy is achievedwith less than Qd traditional standards, with 400 ml/min in patients with low weight as long asyou keep the other parameters of renal substitution
