Abstract
Mg kinetics were analyzed in 158 gravid women with normal and toxic pregnancies. Compared to the corresponding values for nonpregnant women, the mother''s Mg during a normal pregnancy is reduced up to 9.2% in the serum and significantly reduced in whole blood up to 7% of normal values. The same conditions also apply to the newborn. During a pathological pregnancy the serum Mg is reduced by 6.3% and whole blood Mg, 6.6% as opposed to nonpregnant women. Serum Mg decline is equally great for primipara and multipara. Blood group of the pregnant women does not influence the Mg concentration. Rh factor has no influence on the course of the Mg concentration during pregnancy. The reduction of the Mg values in whole blood is significantly greater for newborn males than for newborn females. A conclusion about the extent to which Mg affects the Apgar values cannot be made on the basis of these data due to lack of symmetry between the groups compared. Mg changes in mother and child correlate with pregnancy toxicoses and other parameters.
