Antenatal steroids: can we optimize the dose?

Area of Science:

• Obstetrics and Gynecology
• Neonatology
• Pharmacology

Background:

• Antenatal steroid administration is crucial for women at risk of preterm birth.
• A 24 mg dose is considered sufficient, but optimal regimens are debated.

Purpose of the Study:

• To review optimal antenatal steroid treatment protocols.
• To address data gaps regarding specific steroids, dosing intervals, gestational age, and long-term effects.

Main Methods:

• Literature review of studies on antenatal steroid treatment.
• Analysis of data on dosing, intervals, and treatment courses.

Main Results:

• 12-h and 24-h dosing intervals are equally effective for respiratory distress syndrome prevention.
• Reduced single steroid doses decrease maternal side effects.
• Multiple corticosteroid courses correlate with reduced fetal growth and smaller fetal size.

Conclusions:

• Short-term and long-term effects of antenatal steroid regimens on mother and fetus require further investigation.
• Long-lasting effects of antenatal glucocorticoid exposure in term-born children warrant consideration.
