[Clinical studies on the concentration of free amino acids in plasma and urine during post-aggression metabolism. II].
Our first report concerned the changes in the concentration of free plasma amino acids within the framework of postaggression metabolism, resulting from surgical intervention and parenteral nutrition. This study with 23 operated patients is intended to show whether an amino acid mixture is suited for parenteral nutrition if the particular metabolic action mentioned above is taken into consideration in the composition of the solution. We have shown that the change in the concentration of free plasma amino acids is very small during continuous infusion for 4 postoperative days in steady state and insignificant in comparison to the normal pattern of healthy subjects, except for phenylalanine. With a quota of 2.75% of the supply, the renal loss of free amino acids is clinically unimportant. We believe that an amino acid solution of such composition is suited for infusion in the postoperative and posttraumatic phase whereby our recommendation is explicitly limited to this indication.
