Antenatal Corticosteroids for Fetal Lung Maturity

By the end of this lesson, you will be able to: 1. Explain how antenatal corticosteroids improve fetal lung transition at birth. 2. Identify when antenatal corticosteroids are indicated, including the Canadian late-preterm and borderline-viability decisions. 3. Select the correct betamethasone or dexamethasone regimen, route and timing. 4. Recognise when infection, care limitations or an urgent indication for delivery changes the plan. 5. Anticipate maternal hyperglycaemia, transient fetal effects and neonatal hypoglycaemia. 6. Apply repeat-course guidance and distinguish an isolated expected steroid effect from a finding that requires escalation.
