    Area of Science:

    • Obstetrics and Gynecology
    • Cardiovascular Physiology
    • Maternal-Fetal Medicine
    • Clinical Nutrition

    Background:

    • Human pregnancy induces substantial cardiovascular adaptations, including increased cardiac output and blood volume, alongside decreased systemic vascular resistance and mean arterial pressure.
    • Magnesium (Mg2+) is implicated in physiological changes during pregnancy and cardiovascular abnormalities.
    • Magnesium is a critical electrolyte with established roles in managing uterine contractility and neuronal/vascular smooth muscle activity.

    Purpose of the Study:

    • To review alterations in magnesium (Mg2+) metabolism during human pregnancy.
    • To discuss challenges associated with magnesium metabolism and its parenteral administration in treating pre-eclampsia and eclampsia.
    • To examine the role of magnesium in labor management, including prophylaxis against premature labor and premature rupture of membranes.

    Main Methods:

    • Literature review focusing on magnesium metabolism during pregnancy.
    • Analysis of existing research on magnesium's therapeutic use in obstetric complications.
    • Synthesis of data regarding magnesium's role in labor and prevention of preterm birth.

    Main Results:

    • Pregnancy is associated with significant cardiovascular adjustments.
    • Magnesium (Mg2+) plays a vital role in managing various pregnancy-related conditions, including pre-eclampsia and preterm labor.
    • Parenteral magnesium administration presents specific considerations for treating severe hypertensive disorders of pregnancy.

    Conclusions:

    • Alterations in magnesium (Mg2+) metabolism are observed during pregnancy and may contribute to cardiovascular changes.
    • Magnesium sulfate is a key therapeutic agent for pre-eclampsia, eclampsia, and preterm labor.
    • Further understanding of magnesium's role can optimize its use in obstetric care and improve maternal and fetal outcomes.
