Core Concept: Antenatal corticosteroids (such as dexamethasone or betamethasone) are administered to pregnant women at risk of preterm delivery (typically between 24 and 34 weeks) to accelerate fetal organ development.
Clinical Presentation:
- Premature rupture of membranes (PROM) or preterm labor.
Diagnosis:
- *First-line:* Clinical diagnosis of PROM (sterile speculum exam showing pooling, positive nitrazine/fern test).
- *Gold Standard:* Ultrasound to confirm gestational age and fetal well-being.
Management:
- *Acute:* Administer IM corticosteroids to *promote fetal lung maturation* by stimulating the production of surfactant, significantly reducing the risk of Neonatal Respiratory Distress Syndrome (RDS), intraventricular hemorrhage, and neonatal mortality.
- *Definitive:* Monitor for signs of infection (chorioamnionitis) and manage preterm delivery in a NICU-equipped facility.
