[Magnesium level in the serum and erythrocytes during pregnancy, delivery and puerperium]
Complexometric determinations of serum magnesium levels, moreover partly of Mg concentrations in whole blood, and withal determinations of hematocrit in 489 healthy pregnancies, parturients, puerperants (1 to 10 days post partum), and nonpregnant women were performed. By aid of these values we were able to calculate Mg concentrations in 100 ml erythrocytes (Mg E 100). The apparent decrease of serum Mg during pregnancy may be founded according to the changes of the plasma volume. However, actually the total (absolute) ammount of serum Mg is increased in pregnancy. We suppose some influences on serum Mg due to stimulation of the thyroid gland in pregnancy and further those of Mg being released from the muscular cells of uterus those been destroyed after delivery. The increased erythrocyte Mg during pregnancy and post partum confirm the view that there are no corresponding relations between Mg concentrations of serum and those of erythrocytes. The possible causes of the increase of erythrocyte Mg in pregnancy are discussed in detail.
