Emergency Cesarean Section is Indicated
This patient requires immediate cesarean delivery due to the combination of complete breech presentation with ruptured membranes and established labor. 1
Critical Contraindications to Vaginal Breech Delivery
This clinical scenario presents multiple absolute contraindications to attempting vaginal breech delivery:
- Ruptured membranes with breech presentation is a relative-to-absolute contraindication for vaginal delivery, particularly when combined with active labor 2
- Premature rupture of membranes with an unripe cervix (4 cm dilation represents early active phase) is specifically listed as a relative contraindication to vaginal breech delivery 2
- The patient is already in established labor (4 cm dilated) with ruptured membranes, eliminating the window for external cephalic version 3
Why Other Options Are Inappropriate
External Cephalic Version (Option D) is Contraindicated
- External cephalic version after membrane rupture in active labor carries unacceptable risks including umbilical cord prolapse, as documented in case reports where successful version was followed by cord prolapse requiring emergency cesarean 3
- Version is only considered before labor onset or in very early labor with intact membranes; this patient is beyond that window 3
Oxytocin Induction (Option A) is Dangerous
- Augmenting labor in a breech presentation with ruptured membranes significantly increases neonatal morbidity and mortality risk 2
- The neonatal mortality and morbidity rate is 4 times higher after vaginal breech delivery compared to cesarean delivery 2
- Attempting vaginal delivery in this scenario exposes the fetus to risks of umbilical cord prolapse, placental abruption, and fetal death 4
Waiting (Option B) Increases Risk
- Prolonged rupture of membranes increases infection risk for both mother and fetus without improving the delivery prospects 4
- The patient is already in active labor with no prospect of spontaneous version 3
- Delaying definitive management only extends the period of membrane rupture, compounding maternal and fetal risks 5
Evidence-Based Rationale
- Cesarean delivery is preferred for obstetric indications including breech presentation, particularly when combined with ruptured membranes 1
- Breech presentation with PROM at term should proceed to cesarean section when other risk factors are present, such as early labor and lack of favorable conditions for vaginal delivery 5
- The fetal weight of 2.9 kg is appropriate for cesarean delivery without concerns for extreme prematurity 2
Critical Safety Considerations
- The reactive cardiotocography indicates current fetal well-being, but this can deteriorate rapidly with breech presentation and ruptured membranes 4
- Umbilical cord prolapse risk is significantly elevated in breech presentations with ruptured membranes, making expeditious delivery essential 4, 3
- Maternal complication rates with cesarean delivery, while higher than uncomplicated vaginal delivery, are acceptable when weighed against the 4-fold increase in neonatal mortality/morbidity with attempted vaginal breech delivery 2
