Influence of gestational age.

<p>The figure shows a different impact of parenteral intake of amino acids and lipids on base excess levels according to gestational age categories.</p

pH and base excess in the first week of life.

<p>The figure shows the trend for mean pH and base excess (uncorrected) in the three groups during the first week of life. Bicarbonate administration is also shown.</p

Amino acid intakes and base excess.

<p>The figure shows the scatter diagram and regression line between daily amino acid intravenous intakes and base excess. Amino acid intake was considered from one day before and expressed as g/kg/d. Base excess was corrected for the administration of bicarbonate. Records with lactate > 4 mmol/L were excluded. Correlation coefficient r = 0.51, P<0.001.</p

Lipid intakes and base excess.

<p>The figure shows the scatter diagram and the regression line between the daily lipid intravenous intakes and the base excess. Lipid intake was considered from one day before and expressed as g/kg/d. Base excess was corrected for the administration of bicarbonate. Records with lactate > 4 mmol/L were excluded. Correlation coefficient r = 0.50, P<0.001.</p
