What is a Cesarean section?

Cesarean section, C-section, or Cesarean birth is the surgical delivery of a baby through a cut (incision) made in the mother's abdomen and uterus. Healthcare providers use it when they believe it's safer for the mother, the baby, or both.

The incision made in the skin may be:

• Up-and-down (vertical). This incision extends from the belly button to the pubic hairline.

or

• Across from side-to-side (horizontal).This incision extends across the pubic hairline. It's used most often, because it heals well and there is less bleeding. 

The type of incision used depends on the health of the mother and the fetus. The incision in the uterus may also be either vertical or horizontal.

Why might I need a C-section?

If you can't deliver vaginally, C-section allows the fetus to be delivered surgically. You may be able to plan and schedule your Cesarean. Or, you may have it done because of problems during labor.

Several conditions make a Cesarean delivery more likely. These include:

• Abnormal fetal heart rate. The fetal heart rate during labor is a good sign of how well the fetus is doing. Your provider will monitor the fetal heart rate during labor. The normal rate varies between 120 to 160 beats per minute. If the fetal heart rate shows there may be a problem, your provider will take immediate action. This may be giving the mother oxygen, increasing fluids, and changing the mother's position. If the heart rate doesn’t improve, he or she may do a Cesarean delivery.

• Abnormal position of the fetus during birth. The normal position for the fetus during birth is head-down, facing the mother's back. Sometimes a fetus is not in the right position. This makes delivery more difficult through the birth canal.

• Problems with labor. Labor that fails to progress or doesn't progress the way it should.

• Size of the fetus. The baby is too large for your provider to deliver vaginally.

• Placenta problems. This includes placenta previa, in which the placenta blocks the cervix. (Premature detachment from the fetus is known as abruption.)

• Certain conditions in the mother, such as diabetes, high blood pressure, or HIV infection

• Active herpes sores in the mother’s vagina or cervix

• Twins or other multiples

• Previous C-section

Your healthcare provider may have other reasons to recommend a Cesarean delivery.

What are the risks of a C-section?

Some possible complications of a C-section may include:

• Reactions to the medicines used during surgery

• Bleeding

• Abnormal separation of the placenta, especially in women with previous Cesarean delivery

• Injury to the bladder or bowel

• Infection in the uterus

• Wound infection

• Trouble urinating or urinary tract infection

• Delayed return of bowel function

• Blood clots

After a C-section, a woman may not be able to have a vaginal birth in a future pregnancy. It will depend on the type of uterine incision used. Vertical scars of the uterus are not strong enough to hold together during labor contractions, so a repeat C-section is necessary.

You may have other risks that are unique to you. Be sure to discuss any concerns with your healthcare provider before the procedure, if possible.

How do I get ready for a C-section?

• Your healthcare provider will explain the procedure to you and you can ask question.

• You will be asked to sign a consent form that gives your permission to do the procedure. Read the form carefully and ask questions if something is unclear.

• You will be asked when you last had anything to eat or drink. If your C-section is planned and requires general, spinal, or epidural anesthesia, you will be asked to not eat or drink anything for 8 hours before the procedure.

• Tell your healthcare provider if you are sensitive to or are allergic to any medicine, latex, iodine, tape, or anesthesia.

• Tell your healthcare provider of all medicine (prescription and over-the-counter), vitamins, herbs, and supplements that you are taking.

• Tell your healthcare provider if you have a history of bleeding disorders or if you are taking any blood-thinning medicines (anticoagulants), aspirin, or other medicines that affect blood clotting. You may be told to stop these medicines before the procedure.

• You may be given medicine to decrease the acid in your stomach. These also help dry the secretions in your mouth and breathing passages.

• Plan to have someone stay with you after a C-section. You may have pain in the first few days and will need help with the baby.

• Follow any other instructions your provider gives you to get ready.

What happens during a C-section?

A C-section will be done in an operating room or a special delivery room. Procedures may vary depending on your condition and your healthcare provider's practices.

In most cases, you will be awake for a C-section. Only in rare cases will a mother need medicine that puts her into a deep sleep (general anesthesia). Most C-sections are done with a regional anesthesia such as an epidural or spinal. With these, you will have no feeling from your waist down, but you will be awake and able to hear and see your baby as soon as he or she is born.

Generally, a C-section follows this process:

1. You will be asked to undress and put on a hospital gown.

2. You will be positioned on an operating or exam table.

3. A urinary catheter may be put in if it was not done before coming to the operating room.

4. An intravenous (IV) line will be started in your arm or hand.

5. For safety reasons, straps will be placed over your legs to hold you on the table.

6. Hair around the surgical site may be shaved. The skin will be cleaned with an antiseptic solution.

7. Your abdomen (belly) will be draped with sterile material. A drape will also be placed above your chest to screen the surgical site.

8. The anesthesiologist or nurse anesthetist will continuously watch your heart rate, blood pressure, breathing, and blood oxygen level during the procedure.

9. Once the anesthesia has taken effect, your provider will make an incision above the pubic bone, either transverse or vertical. You may hear the sounds of an electrocautery machine that seals off bleeding.

10. Your provider will make deeper incisions through the tissues and separate the muscles until the uterine wall is reached. He or she will make a final incision in the uterus. This incision is also either horizontal or vertical.

11. Your provider will open the amniotic sac, and deliver the baby through the opening. You may feel some pressure or a pulling sensation.

12. He or she will cut the umbilical cord.

13. You will get medicine in your IV to help the uterus contract and expel the placenta.

14. Your provider will remove your placenta and examine the uterus for tears or pieces of placenta.

15. He or she will use stitches to close the incision in the uterine muscle and reposition the uterus in the pelvic cavity.

16. Your provider will close the muscle and tissue layers with sutures. He or she will close the skin incision with sutures or surgical staples.

17. Finally, your provider will apply a sterile bandage.
