The concomitant amount of sodium (4 mEq/mL) must be calculated into total electrolyte dose of such prepared solutions. Since phosphate buffer consists of two components; dihydrogen phosphate (H 2 PO 4 –) and hydrogen phosphate (HPO 4-2), there is a dissociation constant that we call the acidity constant of phosphate buffer.The phosphoric acid is a tri protic acid and, therefore, there are three acidity constants for this acid. It has been suggested that patients receiving TPN receive 20 mEq phosphate (13 mmol phosphate)/1000 kcal from dextrose. Intravenous infusion of inorganic phosphate may be accompanied by a decrease in the serum level and urinary excretion of calcium.
