[Optimal dose of amino acids administered in total parenteral nutrition (TPN) of malnourished patients]

Abstract

A plasmatic concentration for each aminoacid, between 1 and 1.5 times the normal value in fasting healthy subjects, is considered as an optimal target during total parenteral nutrition (TPN) in malnourished patients. We have analyzed the correlation between the aminoacid input and the aminoacid plasmatic concentration during TPN at different aminoacid composition. By exponential regression curves we then calculated the input required to keep each aminoacid plasma concentration in the optimal range.
