In breech deliveries, which scenario is most complicated?

• A. Cervix constricts around head
• B. Neonate's head too large to fit
• C. Birth canal has meconium present to aspirate
• D. Neonate starts to breathe after thorax delivered

Answer: (A)

In a breech delivery, the most complicated moment is when the cervix constricts tightly around the head. That tight ring can trap the head and prevent it from delivering, creating a dangerous delay that risks hypoxia for the newborn and can lead to tissue injury or further complications. Because the body has already come through, the head is the last part to deliver, so any obstruction at the cervix directly blocks the final stage and demands immediate, skilled maneuvers to relieve the constriction and enable head delivery.

Other scenarios, while serious, don’t pose the same immediate, life-threatening delivery obstacle. A head that’s simply large enough to cause difficulty may be managed with careful techniques and positioning. Meconium in the birth canal increases the risk of aspiration and requires careful resuscitation steps, but it’s a different type of challenge. The baby beginning to breathe after the thorax is delivered is part of normal transition and not by itself a complication.
