J P Elliott

    American Journal of Obstetrics and Gynecology
    |October 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Magnesium sulfate effectively inhibits premature labor, delaying delivery in most cases with a low failure rate. This inexpensive and relatively safe tocolytic agent demonstrated minimal side effects in a retrospective study.

    Area of Science:

    • Obstetrics and Gynecology
    • Pharmacology
    • Maternal-Fetal Medicine

    Background:

    • Premature labor is a significant obstetric concern.
    • Magnesium sulfate (MgSO4) has been utilized as a tocolytic agent.
    • Limited data exists on its efficacy and safety in diverse patient populations.

    Purpose of the Study:

    • To evaluate the effectiveness of magnesium sulfate (MgSO4) in inhibiting premature labor.
    • To assess the incidence of side effects and drug discontinuation.
    • To analyze the success rate of MgSO4 as a tocolytic agent in a large patient cohort.

    Main Methods:

    • Retrospective review of 355 patients treated for premature labor with MgSO4.
    • Analysis of patient demographics including singleton/multiple gestations and membrane status.

  • Documentation of delivery delay, tocolysis failure, and adverse events.

    • Main Results:

    • Delivery was successfully delayed in the majority of patients.
    • Low incidence of unexplained tocolysis failure (2%).
    • Side effects occurred in 7% of patients, necessitating drug cessation in only 2%.

    Conclusions:

    • Magnesium sulfate is a successful, inexpensive, and relatively non-toxic tocolytic agent.
    • It demonstrates a high success rate in delaying delivery for premature labor.
    • The agent is well-tolerated with a low rate of significant adverse effects.
