Hypercalcemia associated with parenteral amino acid and dextrose infusion.


A patient receiving parenteral nutrition with an amino acid dextrose solution developed hypercalcemia which seemed related to the rate of nutrient infusion. In a retrospective study of patients receiving parenteral nutrition over a 3-month period six of 72 (8%) developed hypercalcemia. After changes in infusion rate there were corresponding changes in the serum calcium concentration. There was a significant correlation between the serum calcium concentration and the average infusion rate over the preceding four days (p = 0.012). This was even more significant (p less than 0.005) when ionized calcium was calculated to diminish the effects of calcium binding by proteins.
