“…When oedema-free patients have been studied the results have been somewhat conflicting. Carrol, Gotterer, and Altshuler (1965) found an increase in exchangeable sodium, whereas Oleson (1966) found the level to be insignificantly higher than in control groups, and Lockey et al (1966) found only one patient to have a level at the upper limit of the normal range.…”

“…It has been suggested (Lockey, Longmore, Ross, and Sturridge, 1966) that patients receiving diuretic therapy are more likely to be potassium depleted and would therefore be more liable to postoperative arrhythmias. The relation between potassium depletion and diuretic treatment has been examined, as has the incidence of arrhythmias in the immediate postoperative period.…”

Summary: Exchangeable sodium and potassium, total body water, and sulphate space were measured in 42 patients with severe valvular heart disease who were free of oedema. Compared with normal subjects of the same height, no increase in exchangeable sodium was found but a mean potassium depletion of 27% was shown. This depletion was not related to diuretic therapy, and no relationship between the degree of depletion and postoperative arrhythmias was found. It is concluded that the major cause of the low exchangeable potassium is the reduction in cell mass that occurs in chronic heart disease, and that there is no significant fall in the intracellular potassium concentration.

“…Further samples were obtained 5 min after start of bypass, at mid-bypass, just before the end of bypass and after bypass just before the patient left the operating room. Postoperative specimens were drawn at 4-hourly intervals during the first postoperative day (specimens [1][2][3][4][5][6] and at 8-hourly intervals during the second postoperative day (specimens 7-9). Urine was collected during bypass and for 48 hours after the procedure, at 4-hourly intervals for the first 24 hours and at 8-hourly intervals during the seeend day.…”

“…Patients in CCF with oedema have been shown to have high concentrations of exchangeable sodium even when this is expressed as mmoljkg body weight (Farber & Soberman, 1956;Birkenfeld, Leibman, O'Meara & Edelman, 1958). In patients free of oedema, results have varied : Carroll, Gotterer & Altshuler (1965) found an increase in exchangeable sodium, whereas Lockey, Longmore, Ross & Sturridge (1966) and Oleson (1966) found no significant increase. Flear, Quinton, Carpenter, Domenet & Sivyer (1966) and Lockey et al (1966) have reported a significant depletion of total exchangeable potassium in patients with 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, patients in failure had an excess of total body water, extracellular fluid and total exchangeable sodium, and had less total exchangeable potassium.3. There was a decrease in total exchangeable sodium and an increase in total exchangeable potassium on recovery from congestive cardiac failure.4. After treatment of cardiac failure, intracellular potassium increased and intracellular sodium was decreased. 5. The low total exchangeable potassium in cardiac failure is not simply due to loss of lean body mass.
