Trace metal profile of parenteral nutrition solutions

EC Hauer and MV Kaminski Jr

Zinc, copper, iron, magnesium, and chromium were analyzed in commercially prepared total parenteral nutrition solutions of amino acid/protein hydrolysate, dextrose, lipid, and water from several manufacturers. Concentrations of each varied with both the manufacturer and the solution lot number, with the greatest differences observed for zinc (0.026 to 4.04 mg/liter) and iron (0.025 to 1.370 mg/liter). Since the consequences of prolonged total parenteral nutrition with trace- metal-deficient solutions are dependent upon the physical state of the patients, the duration of hyperalimentation and problems associated with trauma, it is recommended that the endogenous concentrations described be supplemented as needed for each patient. This need is difficult to determine, however, because little is known about the clinical effect of any trace-metal-deficiency state developing in patients receiving long-term total parenteral nutrition.
