Modeled urea distribution volume and mortality in the HEMO Study.
BACKGROUND AND OBJECTIVES In the Hemodialysis (HEMO) Study, observed small decreases in achieved equilibrated Kt/V(urea) were noncausally associated with markedly increased mortality. Here we examine the association of mortality with modeled volume (V(m)), the denominator of equilibrated Kt/V(urea). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Parameters derived from modeled urea kinetics (i...
متن کاملEffect of hemodialysis on blood volume distribution and cardiac output.
Effects of hemodialysis on extracellular fluid volume distribution, left ventricular volumes, and cardiac output were determined in patients with end-stage renal disease (n = 19). Distribution of extracellular fluid loss from hemodialysis differed widely among patients, so that weight change correlated weakly with contraction of total blood volume (index of determination 29%, p less than 0.05)....
متن کاملUrea distribution in renal failure.
An assessment of intracellular urea removed during haemodialysis has been made from urea extraction and plasma urea estimations. An apparent wide variation in the movement of intracellular urea in patients with acute renal failure from obstetric and traumatic causes and with chronic renal failure is reported.A method for the estimation of red cell water urea is presented. In two patients with c...
متن کاملHemodialysis Volume-Associated Ambulatory Blood Pressure Patterns in Hemodialysis Patients
Although volume excess causes hypertension, whether it also affects circadian patterns of arterial pressures among hemodialysis patients remains unknown. To test the notion of whether volume overload is associated with a unique blood pressure (BP) “signature,” a posthoc analysis was performed among 145 patients participating in the Dry-Weight Reduction in Hypertensive Hemodialysis Patients rand...
متن کاملNear-infrared spectroscopy for measuring urea in hemodialysis fluids.
BACKGROUND Near-infrared spectroscopy is proposed as a method for providing real-time urea concentrations during hemodialysis treatments. The feasibility of such noninvasive urea measurements is evaluated in undiluted dialysate fluid. METHODS Near-infrared spectra were collected from calibration solutions of urea prepared in dialysate fluid. Spectra were collected over three distinct spectral...
