[The clinical importance of magnesium during neonatal life (author's transl)]. 1976

K D Bachmann, and O Feenders, and H C Dominick

By atomic absorption spectrophotometry (ASS) the magnesium levels in the serum of 50 mothers, their mature healthy infants and the umbilical vein and the umbilical artery were determined. The differences between maternal and neonatal levels and between umbilical vein and umbilical arteries are statistically significant. The results were as follows: Antecubital venous blood of the mother 1.41 +/- 0.38 mval/1, umbilical vein serum 1.59 +/- 0.35 mval/1, umbilical artery 1.65 +/- 0.36 mval/1, neonate 1.68 +/- 0.45 mva1/1. The magnesium concentration in the erythrocytes of neonates was determined for the first time by AAS analysis. A marked variation of the normal was found. It is possible that the determined low magnesium concentrations in the erythrocytes of neonates were due to latent magnesium deprivation in these infants. The mean values for the erythrocytes of the mother (4.38 +/- 1.16 mva1/1) and the erythrocytes from the umbilical vein (3.99 +/- 1.50 mva1/1) differed significantly, whereas the erythrocytes from the umbilical vein and from the peripheral venous blood of the neonate showed no statistically significant difference. Hypomagnesiumia and hypermagnesiumia are described in brief.

UI MeSH Term Description Entries
D007231 Infant, Newborn An infant during the first 28 days after birth. Neonate,Newborns,Infants, Newborn,Neonates,Newborn,Newborn Infant,Newborn Infants
D008274 Magnesium A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D008275 Magnesium Deficiency A nutritional condition produced by a deficiency of magnesium in the diet, characterized by anorexia, nausea, vomiting, lethargy, and weakness. Symptoms are paresthesias, muscle cramps, irritability, decreased attention span, and mental confusion, possibly requiring months to appear. Deficiency of body magnesium can exist even when serum values are normal. In addition, magnesium deficiency may be organ-selective, since certain tissues become deficient before others.
