What Is Cesarean Delivery?

What is a cesarean delivery?

A cesarean delivery, also called a cesarean section or c-section, is surgery to deliver a baby. The baby is taken out through your abdomen (belly). In the United States, almost one in three babies are born this way. Some cesarean deliveries are planned. Others are emergency cesarean deliveries, which are done when unexpected problems happen during delivery.

When is a cesarean delivery needed?

You may need a cesarean delivery because:

• You have health problems, including infection
• You are carrying more than one baby
• Your baby is too big
• Your baby is in the wrong position
• Your baby's health is in danger
• Labor is not moving along as it should
• There are problems with your placenta (the organ that brings oxygen and nutrients to your baby)

Not everyone who has had a cesarean delivery before will need another one next time. You may be able to have a vaginal birth after cesarean (VBAC). Talk to your health care provider about what is right for you.

How is a cesarean delivery done?

Before the surgery, you will be given pain medicine. Depending on your circumstances, you might get:

• An epidural block, which numbs the lower part of the body through an injection in the spine.
• A spinal block, which numbs the lower part of the body through an injection directly into the spinal fluid.
• General anesthesia, which makes you unconscious during the surgery. This is often used during emergency cesarean deliveries.

During the surgery, the surgeon will:

• Make a cut in your abdomen and uterus. The cut is usually horizontal, but in some cases it may be vertical.
• Open the amniotic sac and take out your baby.
• Cut the umbilical cord and the placenta.
• Close the uterus and abdomen with stitches that will later dissolve.

What are the risks of a cesarean delivery?

A cesarean delivery is relatively safe for you and your baby. But it is still a major surgery, and it carries risks. They may include:

• Infection
• Blood loss
• Blood clots in the legs, pelvic organs, or lungs
• Injury to surrounding structures, such as the bowel or bladder
• A reaction to the medicines or anesthesia used

Some of these risks do also apply to a vaginal birth. But it does take longer to recover from a cesarean delivery than from a vaginal birth. And having a cesarean delivery can raise the risk of having difficulties with future pregnancies. The more cesarean deliveries you have, the more the risk goes up.
