    Summary

    A fenoterol sensitivity test identified hypersensitivity in 4.2% of pregnant women before premature delivery treatment. Gradual cessation of sympathomimetic drugs is crucial to prevent complications during tocolytic therapy.

    Area of Science:

    • Obstetrics and Gynecology
    • Pharmacology
    • Maternal-Fetal Medicine

    Background:

    • Premature delivery necessitates tocolytic treatment.
    • Sympathomimetic agents like fenoterol are commonly used.
    • Assessing individual drug sensitivity is important for patient safety.

    Purpose of the Study:

    • To determine individual sensitivity to fenoterol in pregnant women.
    • To evaluate the impact of fenoterol on maternal heart rate.
    • To identify potential complications associated with tocolytic therapy.

    Main Methods:

    • Retrospective analysis of maternal heart rate changes.
    • Infusion of 0.4 microgram/kg/min fenoterol in 95 pregnant women.
    • Monitoring patients prior to tocolytic treatment for premature delivery.

    Main Results:

    • 4.2% of pregnant women exhibited hypersensitivity to fenoterol.
    • A significant decrease in beta sensitivity was observed with the onset of premature labor.
    • No adverse pathological effects were noted in newborns exposed to fenoterol.

    Conclusions:

    • Individual fenoterol sensitivity testing is recommended.
    • Stepwise discontinuation of sympathomimetic medication is advised to prevent complications.
    • Fenoterol treatment appears safe for newborns when used cautiously.
