[Plasma amino acid level in premature and newborn infants after infusion of 2 commercial pediatric amino acid solutions].

13 preterms and 10 term-babies were fed with two commercially available amino acid solutions (mother milk-adapted and requirement-adapted) under the same test conditions. Method and results were compared and discussed. None of the solutions showed amino acid imbalances 4 hours after discontinuation of continuous infusion over 20 hours. This applies also to glutamic and aspartic acid which were not contained in the mother milk-adapted solution. Threonine and methionine showed more favorable levels after the infusion of the mother milk-adapted solution It was pointed out that additional monitoring of levels is mandatory in the course of continuous i.v. amino acid supplies.
