title: Parenteral infusion with an admixture of amino acids, dextrose, and fat emulsion solution: compatibility and clinical safety.
abstract: Fat emulsions are increasingly utilized as intravenous calorie sources in patients requiring total parenteral nutrition. In the United States, they are traditionally administered separate from the dextrose/amino acid solution because of concern regarding physical stability and clinical safety when fat emulsions are administered, having been mixed with the dextrose solution. The separate infusion entails multiple manipulations of the infusion system with increased risk of contamination and sepsis and increased cost in maintaining two infusion lines. This prospective sequential two-phase clinical study evaluated solution compatibility and clinical safety of an admixture of fat emulsion (Intralipid 20%), dextrose, amino acids (Veinamine 8%), electrolytes, vitamins, and trace minerals. Continuous infusion of this solution in 25 adult patients from 2 to 35 days did not result in any adverse clinical reactions or abnormal laboratory parameters. Gross, visual examination and in vitro analysis of the admixture solutions revealed no physical instability or changes in fatty acid composition in admixture solutions stored at 4 degrees C for up to 6 weeks.
