    American Journal of Obstetrics and Gynecology
    |June 1, 1985
    PubMed
    Summary

    Continuous long-term intravenous beta-sympathomimetic tocolysis is safe for selected patients, with pronounced side effects mainly in the initial days. This therapy can prolong pregnancy, leading to better outcomes under close medical supervision.

    Area of Science:

    • Obstetrics and Gynecology
    • Pharmacology

    Background:

    • Tocolysis is used to prevent preterm birth.
    • Long-term intravenous beta-sympathomimetic agents are a common tocolytic treatment.
    • Concerns exist regarding the safety and efficacy of prolonged tocolytic therapy.

    Purpose of the Study:

    • To evaluate the clinical course and outcomes of patients receiving continuous long-term intravenous beta-sympathomimetic tocolysis.
    • To assess the safety and tolerability of this therapeutic approach.

    Main Methods:

    • Retrospective analysis of 16 patients treated with continuous long-term intravenous beta-sympathomimetic tocolysis (≥1 week).
    • Therapy adjusted to control uterine activity and maintain vital signs.
    • Treatment continued until oral transition, fetal maturity, or delivery indications.

    Main Results:

    • Cardiovascular and metabolic effects were most pronounced in the first 3-4 days, then normalized.
    • No patients discontinued treatment due to drug-related issues, ECG changes, chorioamnionitis, or fever.
    • Pregnancy was prolonged in the studied cohort.

    Conclusions:

    • Continuous long-term intravenous beta-sympathomimetic tocolysis is a safe option for selected patients.
    • Close monitoring is essential for managing potential side effects.
    • This therapy can potentially improve pregnancy outcomes by prolonging gestation.
