Physicochemical Stability of Two Types of Intravenous Lipid Emulsion as Total Nutrient Admixtures

Abstract

Because the final macronutrient concentrations were held constant, the instability seen with the LCT-based TNAs of higher volumes may result from dilution of the electrolyte concentrations that unfavorably alters the electrical double layer and irreversibly commits the emulsion to an unstable state. The greater physicochemical stability achieved with the MCT/LCT-based TNAs, in turn, likely results from the smaller lipid droplet sizes, which may be an inherent property of MCTs.
