Urinary Excretion of Pyruvic Acid and Lactic Acid in Premature and Full‐Term Newborn Infants

Abstract

Summary The urinary excretion of pyruvic acid and lactic acid per kg of body weight was observed to be higher in premature than in full‐term newborn infants. Mild toxemia of the mother did not influence the urinary pyruvic acid content in the child. Both the pyruvic and the lactic acid values in urine were equally high in the two age groups of premature infants, aged 1–9 days and 10–30 days.

“…In particular, urinary excretion of lactate, although doubled, remains negligible. These results arc quite different from those of G oldman et al [14], but it must be emphasized that the values of lactate urinary excretion reported by these authors, even with nonacidified milk, are 10 times higher than our results and those of T oivanen et al [36].…”
