During a breech delivery, what should be done if the baby's head does not readily deliver?

In a breech delivery, when the baby's head does not readily deliver, inserting a gloved hand to relieve pressure on the umbilical cord is crucial for ensuring the well-being of the infant. During a breech presentation, there is a risk that the umbilical cord could become compressed as the baby's body pushes against the mother's pelvis, which can lead to a decrease in blood flow and oxygen to the baby.

By gently inserting a gloved hand, a healthcare provider can help alleviate this pressure, thereby ensuring that blood flow remains adequate while waiting for further delivery. This action is often referred to as "cord management" during a breech delivery and is a critical step in managing potential complications.

The other options may not be the best course of action in this situation: waiting for the head to deliver naturally could increase the risk of cord compression; calling for additional medical assistance may take time that is critical for the baby; and performing an emergency C-section may not be immediately feasible or necessary if the situation can be managed with cord relief.

Thus, the appropriate response when the baby's head does not readily deliver is to relieve any pressure on the umbilical cord by inserting a gloved hand.
