[Nitrogen balance in premature babies during parenteral nutrition (author's transl)].

This paper represents a continuation of research into the nitrogen (N) balances in seriously premature babies. During parenteral nutrition an increased amount of 400 mg N/kg body weight/24 hrs. was administered in the form of L-aminoacids together with glucose and fat emulsion. No change in the amount of retained aminoacids occurred (some 80%). On the other hand several increased values of N-metabolites demonstrate that this dosis of aminoacids can be considered as the maximal value.
