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...
متن کاملUse of Systemic Blood Urea Nitrogen Levels
Urea rebound refers to an early postdialysis phenomenon in which urea returns to the systemic circulation, raising the blood level to a near plateau over a period of 0.5 to 1 hour [1]. The urea involved is believed to have come from either the intracellular compartment by means of diffusion resulting from the dialysis-induced concentration gradient [2,3], or tissues poorly perfused as a result ...
متن کاملA Coulometric Determination of Urea Nitrogen in Blood and Urine.
Since the ammonia undergoes a 3-electron change, 1 mole is equal to 3 equivalents of the generated titrant. Recently we (lescril)ed an improved cud-point (letection for this system and applied it to titration of as little as 1.4 g. ammonia (2). This method has been extended to titration of ammonia formed by the action of urease on urea in blood and urine. In urine samples, ammonia may be titrat...
متن کاملGentamicin- and cephalothin-associated rises in blood urea nitrogen.
Standardized rates of drug-attributed rises in blood urea nitrogen were 8.6%, 2.9%, and 9.3%, respectively, in patients receiving gentamicin alone, cephalothin alone, and both drugs together. These results provide evidence against a substantial synergism between the two drugs in the production of impaired renal function.
