Summary
Multiple courses of antenatal steroids significantly reduce respiratory distress syndrome (RDS) in preterm infants compared to single courses. This approach shows no increased risk of neonatal sepsis or impaired fetal growth.
Area of Science:
- Neonatal Medicine
- Obstetrics
- Pharmacology
Background:
- Antenatal steroid administration is crucial for fetal lung maturation.
- The optimal regimen for antenatal steroid use in preterm births remains under investigation.
Purpose of the Study:
- To compare the effectiveness of single versus multiple courses of antenatal steroids in preterm neonates.
- To identify potential adverse effects associated with multiple antenatal steroid courses.
Main Methods:
- Retrospective analysis of neonatal outcomes for infants weighing ≤1750g at birth.
- Comparison of infants receiving single versus two or more courses of antenatal steroids.
Main Results:
- Multiple antenatal steroid courses were associated with significantly higher gestational age and birth weight.
- A significant reduction in respiratory distress syndrome (RDS) incidence was observed with multiple courses (OR 0.35; P = .003).
- No significant differences in other perinatal outcomes or increased neonatal sepsis were noted.
Conclusions:
- Multiple antenatal steroid courses are more effective than single courses in reducing RDS in preterm infants.
- The use of multiple antenatal steroid courses does not appear to increase the risk of neonatal sepsis or affect fetal growth.
