[Dosage of calcium and phosphate in parenteral feeding].

In a carbohydrate combination solution containing 12.5 mEq/1 calcium and 12 mmol/1 phosphate the concentrations of calcium and phosphate were kept constant during parenteral infusion therapy with carbohydrate, at a rate of 0.5 g/kg/h and amino acids at a rate of 0.1 g/kg/h. Balance for calcium and phosphate was positive. Calcium excretion was slightly above the levels determined in oral nutrition. A slight modification of calcium supplement by changing the concentration of the solution to 10 mEq/1 is suggested.
