Emergency Cesarean Section is Indicated

In a 38-week pregnant woman with complete breech presentation, 4 cm dilation, and no cervical change after 2 hours, proceed immediately to cesarean delivery. 1

Why Cesarean Section is the Correct Answer

Breech Presentation in Active Labor Mandates Cesarean Delivery

  • The American College of Obstetricians and Gynecologists recommends cesarean delivery for breech presentation at term in active labor, particularly when labor has already commenced. 1
  • The combination of breech presentation with labor arrest (no cervical change after 2 hours at 4 cm dilation) significantly increases risks of cord prolapse, head entrapment, and birth trauma if vaginal delivery is attempted. 1
  • At 4 cm dilation with regular contractions sufficient to bring the patient to labor and delivery, this patient is in active labor, not latent labor. 1

Two-Hour Arrest Threshold is Appropriate

  • Arrest of active phase labor (no cervical change after 2 hours at 4 cm dilation) is a strong indication for cesarean delivery. 1
  • Recent evidence suggests that 2 hours of arrest is safer as a threshold for intervention rather than waiting the traditional 4 hours, and breech presentation lowers this threshold further. 1
  • The reactive CTG confirms fetal well-being at present, but this does not eliminate the substantial risks of continuing labor with breech presentation and arrest. 1

Why Other Options are Incorrect

Oxytocin Augmentation (Option A) is Contraindicated

  • Do not attempt oxytocin augmentation for breech presentation with arrest - this increases risks without improving outcomes and may worsen fetal compromise. 1
  • Augmentation in the setting of breech presentation with labor arrest dramatically increases the risk of cord prolapse, head entrapment, and birth trauma without evidence of benefit. 1

Waiting 2 More Hours (Option B) is Unsafe

  • Do not wait for the traditional 4-hour arrest threshold when breech presentation is present - the combination of breech with arrest warrants earlier intervention. 1
  • Continuing expectant management exposes both mother and fetus to unnecessary risks of cord prolapse and other complications specific to breech presentation. 1

External Cephalic Version (Option D) is Inappropriate

  • External cephalic version is contraindicated once active labor has begun at 4 cm dilation. 1
  • ECV is a procedure performed in the antepartum period (typically 36-37 weeks) before labor onset, not during active labor with established cervical dilation. 1

Critical Clinical Pitfalls to Avoid

  • Do not consider trial of vaginal breech delivery in the setting of labor arrest - this combination dramatically increases maternal and neonatal morbidity. 1
  • Ensure continuous fetal monitoring is maintained until delivery, as breech presentation carries inherent risks of cord compression and fetal compromise. 1
  • Communicate clearly with the anesthesia team about the urgency classification (urgent cesarean section) to ensure appropriate preparation and minimize decision-to-delivery interval. 2, 3
