Sodium concentration in urine greater than in the plasma: possible biomarker of normal renal function and better outcome in critically ill patients. Anaesth Intensive Care. 2014;42(5):584–91.Maciel AT, Vitorio D, Salles LD, et al. Sodium concentration in urine greater than in the plasma: ...
Eliminated principally in urine as thiocyanate.Some cyanide is expired as hydrogen cyanide. Half-life Sodium nitroprusside: Circulation half-life: 2 minutes. Thiocyanate: 3 days. Special Populations Half-life of thiocyanate is increased in patients with renal failure. ...
Urine is the only route by which sodium excretion can be precisely regulated to match the sodium intake. Depending on the dietary intake and the status of body sodium content, urinary sodium loss can range from less than 1 mmol in a state of sodium deficit, to more than 500 mmol per day...
A thirst-induced increase in fluid intake leads, initially, to an increase in blood volume, which persists until urine and sodium excretion return volume and osmolality to the normal range following reduced release of ADH and the sodium-retaining hormone aldosterone. Guyton’s work was in dogs, ...
With regard to the issue of HCO−3:Na+ stoichiometry, one interesting set of observations in Necturus was the finding that when functioning in the normal reabsorptive direction, this ratio was 3:1, but when bath conditions were changed to reverse the flux direction, the ratio changed to 2...
Inactive metabolite (HPPH) is excreted in urine, mainly as the glucuronide; approximately 60–75% of the daily dose is excreted in this form.Half-lifeOral: About 22 hours.IV: Ranges from 10–15 hours.Special PopulationsTotal plasma phenytoin concentrations are lower in chronic uremic patients ...
1.a soft, silver-white, chemically active metallic element that occurs naturally only in combination: a necessary element in the body for the maintenance of normal fluid balance and other physiological functions.Symbol:Na;at. wt.:22.9898;at. no.:11;sp. gr.:0.97 at 20°C. ...
Fourth, the associations reported in our study may be due in part to confounding by other dietary variables.56 However, the observed association did not change after adjusting for a healthy dietary pattern. Fifth, the measurement of sodium excretion in the 24-hour urine collection method is ...
a hormone which decreases the excretion of sodium in the urine. As the body of the mammal retains more sodium, other osmoregulation systems which sense osmotic pressure in part from the concentration of sodium and water in the blood, act to generate antidiuretic hormone. This, in turn, causes...
On average, 1 week after blood pressure measurement (median, 5; range, 0-17 days at baseline; median, 3 days; range, 0-15 days at follow-up), participants collected an exactly timed 24-hour urine sample in a 2500 mL wide-neck plastic container (Sarstedt article number 77.576, Nümbrecht...
