What is the cephalopelvic disproportion?

Cephalopelvic disproportion occurs when there is mismatch between the size of the fetal head and size of the maternal pelvis, resulting in “failure to progress” in labor for mechanical reasons. Untreated, the consequence is obstructed labor that can endanger the lives of both mother and fetus.

How is cephalopelvic disproportion detected?

A physical examination that measures pelvic size can often be the most accurate method for diagnosing CPD. If a true diagnosis of CPD cannot be made, oxytocin is often administered to help labor progression. Alternatively, the fetal position is changed.

What is cephalopelvic disproportion in pregnancy?

During labor and delivery, a baby has to pass through the narrow opening in the mother’s pelvis. Cephalopelvic Disproportion (CPD) is a condition where the baby has trouble getting through the birth canal because of the size of the baby’s head, the baby’s position, or the size or shape of the mother’s pelvis.

How do you manage cephalopelvic disproportion?

The treatment for CPD is to continue with labor or move on to a cesarean section. The goal of treatment is to have a safe delivery, so the doctors will decide how to treat the condition based on how the delivery is going.

Which type of pelvis leads to CPD?

Cephalopelvic disproportion (CPD) is a pregnancy complication in which there is a size mismatch between the mother’s pelvis and the fetus’ head. The baby’s head is proportionally too large or the mother’s pelvis is too small to easily allow the baby to fit through the pelvic opening.

Can my pelvis be too narrow?

pelvic abnormalities: Some women have a pelvis that causes the baby to turn when approaching the birth canal. Or the pelvis can be too narrow to deliver the baby. Your doctor will assess your pelvis early in the pregnancy to check if you’re at risk for birth canal issues.

Does a small pelvis mean C-section?

The narrower shape of the android pelvis can make labor difficult because the baby might move more slowly through the birth canal. Some pregnant women with an android pelvis may require a C-section. Anthropoid. The elongated shape of the anthropoid pelvis makes it roomier from front to back than the android pelvis.

What happens if your pelvis is too small to give birth?

Android. The narrower shape of the android pelvis can make labor difficult because the baby might move more slowly through the birth canal. Some pregnant women with an android pelvis may require a C-section. Anthropoid.

How common is cephalopelvic disproportion?

CPD happens in about 1 out of every 250 births. In otherwise normal pregnancies, babies are macrosomic 10% of the time. There are several factors that make pregnancies high-risk.

What is the male pelvis called?

It is made up of five fused vertebral bones. The male sacrum is taller and narrower than a female’s. The sacrum is connected to the tailbone, or coccyx, which is made of several fused vertebral bones at the base of the spine. A man’s pelvic bones are typically smaller and narrower than a woman’s.
