A woman with one prior uncomplicated lower segment cesarean section for breech presentation is scheduling an elective repeat cesarean. At what gestation should the procedure be planned, and what complication does this timing specifically minimize compared with earlier delivery?
- A 37 weeks, minimizing maternal wound infection
- B 38 weeks, minimizing neonatal hyperbilirubinemia
- C 39 weeks, minimizing neonatal respiratory morbidity ✓
- D 40 weeks, minimizing risk of unplanned labour
Correct answer: C. 39 weeks, minimizing neonatal respiratory morbidity
Explanation
Elective repeat cesarean is recommended at 39 completed weeks in women with reliable dating. Delivery before 39 weeks significantly increases transient tachypnea of the newborn and respiratory distress syndrome because surfactant maturation is incomplete, and this risk falls sharply at 39 weeks. Waiting to 40 weeks increases the chance of labour onset and emergency surgery, so option D trades a small logistical benefit for avoidable risk.
