Alterations in Exchangeable Sodium Content , " i 0 Sodium 24 Space " and Body Weight During The Treatment of Congestive Failure

چکیده
Serial determinations of the exchangeable sodium content and sodium24 (Na24) space were made by the radioisotope dilution method in patients with congestive failure during the course of intensive therapy. In most instances, the decrease in body weight was too great to be accounted for solely on the basis of the change in sodium24 space or exchangeable sodium content. This excess weight loss is attributed to loss of intracellular fluid.

متن کاملRegression of body compositional abnormalities of heart failure after intracardiac operations.
SUMMARY Alterations in body composition are present in patients with heart disease and conges-tive heart failure, and additional changes occur acutely after corrective surgery. The reversibility and time course of reversion to normal body composition have not been demonstrated. Nine patients were studied preoperatively and 2 to 4 weeks and 6 to 12 mo postoperatively. Measurements were made, usi...
متن کاملExchangeable potassium content of the body in congestive failure; changes during treatment.
The increase in body weight in congestive heart failure is generally attributed to the retention of sodium and water in the extracellular compartment. Important changes also occur in the intra-cellular space, particularly in the metabolism of potassium. The isotope-dilution technic permits more precise determination of the exchangeable potassium content of the body in congestive failure before ...
متن کاملPotassium and sodium distribution in cardiac failure.
1. Total body water, extracellular fluid, total exchangeable potassium and total exchangeable sodium were measured by the multiple isotope-dilution technique in eight patients with congestive cardiac failure. Measurements were made on each patient while in failure and then again after treatment and recovery. 2. Compared with five control subjects in whom the same measurements were made, patient...
متن کاملExchangeable sodium and blood volume in normotensive and hypertensive humans on high and low sodium intake.
Eight normotensive and eight essential hypertensive humans were studied when on high and low sodium intake. Total 24-hr exchangeable body sodium, blood volume, serum sodium concentration, hematocrit, body weight, and mean arterial pressures, when the subjects were supine and upright, were measured. Plasma and nonplasma sodium fractions, nonplasma weight, and plasma, cell, and whole blood volume...
