Blood Urea Nitrogen
Loop diuretics are used in patients with heart failure (HF) to relieve symptoms of systemic and pulmonary venous congestion. Despite their nearly universal use for this indication, loop diuretics have not been shown to improve survival—indeed, a number of recent studies suggest an adverse relationship between the use of loop diuretics and survival (1–3). This is plausible because loop diuretics...

Urea and the clinical value of measuring blood urea concentration
Urea is the principal nitrogenous waste product of metabolism and is generated from protein breakdown. It is eliminated from the body almost exclusively by the kidneys in urine, and measurement of its concentration, first in urine and later in blood, has had clinical application in the assessment of kidney (renal) function for well over 150 years. This is the first of two articles that together...
متن کاملThe Evaluation of Dietary Protein Intake by Calculation of Urea Generation Rate in Chronic Dialysis Patients in Kerman, 2002
Malnutrition is a common problem in chronic dialysis patients. There are several methods for nutritional assessment of hemodialysis patients, such as calculation of urea generation rate. As urea is produced from proteins catabolism and there is a linear correlation between urea generation and protein catabolic rate (PCR), PCR can be calculated by considering urea nitrogen appearence during the ...
متن کاملEstimating total urea removal and protein catabolic rate by monitoring UV absorbance in spent dialysate.
BACKGROUND Dialysate-based, on-line measurements of Kt/V and protein catabolic rate (PCR) in dialysis patients have been considered more accurate compared with measurements on the blood side during dialysis. The primary aim of this study was to compare total removed urea (TRU) and PCR, normalized to body weight (nPCRw), obtained by three dialysate-based methods: (i) on-line ultraviolet (UV) abs...
