[Metabolic balance in newborns receiving parenteral nutrition]

It has been realized a study about energy and nitrogen balances in 23 patients with total parenteral nutrition in order to know how they get weight increase and nitrogen retention. The parameters analysed were nitrogen retention, nitrogen retention/100 g. of weight increase, efficacy in use of nitrogen, metabolized energy and metabolized energy expressed in percentage of intake energy. Positive correlation between intake energy and urinary eliminated energy (p < 0.05) as soon as between intake nitrogen and urinary eliminated nitrogen emphasize among the results. We have verified too that the percentage of metabolized energy over intake energy is upper in operated newborn than in other affected by necrotizing enterocolitis.
