Efecto de ajuste del flujo dializante (Qd) sobre la eficacia en hemodialisis a pacientes de bajo peso

Abstract

Introduction: KDOQI guidelines in 2006 using standard dialysis adequacy Kt / V, where V is volume of distribution of urea, underweight patients have lower total body water, lower V, which could reduce the requirement without affecting Qd the efficiency of dialysis. Objective: To evaluate the effect on the adequacy of dialysis Qd reduction occurs in patients weighing less than or equal to 60 kg who are on hemodialysis. Methodology: Patients with chronic kidney disease on hemodialysis regularly with weight less than or equal to 60 kg of a renal clinic to evaluate two periods I and II, were continued therapy parameters with decrease of Qd for the second period. The variables were collected directly by the researchers of the history. The values thus obtained would be compared using t test or paired variables, and statistical significance of the test 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 statistically significant differences for the variables Kt / V , Hemoglobin and there was a significant reduction in the phosphorus levels. Conclusions: This study demonstrates that adequate therapy is achieved with less than Qd traditional standards, with 400 ml / min in patients with low weight as long as you keep the other parameters of renal substitution.
