Cesarean delivery, also called c-section, is surgery to deliver a baby. The baby is taken out through the mother's abdomen. Most cesarean births result in healthy babies and mothers. But c-section is major surgery and carries risks. Healing also takes longer than with vaginal birth.
Most healthy pregnant women with no risk factors for problems during labor or delivery have their babies vaginally. Still, the cesarean birth rate in the United States has risen greatly in recent decades. Today, nearly 1 in 3 women have babies by c-section in this country. The rate was 1 in 5 in 1995.
Public health experts think that many c-sections are unnecessary. So it is important for pregnant women to get the facts about c-sections before they deliver. Women should find out what c-sections are, why they are performed, and the pros and cons of this surgery.
Your doctor might recommend a c-section if she or he thinks it is safer for you or your baby than vaginal birth. Some c-sections are planned. But most c-sections are done when unexpected problems happen during delivery. Even so, there are risks of delivering by c-section. Limited studies show that the benefits of having a c-section may outweigh the risks when:
A growing number of women are asking their doctors for c-sections when there is no medical reason. Some women want a c-section because they fear the pain of childbirth. Others like the convenience of being able to decide when and how to deliver their baby. Still others fear the risks of vaginal delivery including tearing and sexual problems.
But is it safe and ethical for doctors to allow women to choose c-section? The answer is unclear. Only more research on both types of deliveries will provide the answer. In the meantime, many obstetricians feel it is their ethical obligation to talk women out of elective c-sections. Others believe that women should be able to choose a c-section if they understand the risks and benefits.
Experts who believe c-sections should only be performed for medical reasons point to the risks. These include infection, dangerous bleeding, blood transfusions, and blood clots. Babies born by c-section have more breathing problems right after birth. Women who have c-sections stay at the hospital for longer than women who have vaginal births. Plus, recovery from this surgery takes longer and is often more painful than that after a vaginal birth. C-sections also increase the risk of problems in future pregnancies. Women who have had c-sections have a higher risk of uterine rupture. If the uterus ruptures, the life of the baby and mother is in danger.
Supporters of elective c-sections say that this surgery may protect a woman's pelvic organs, reduces the risk of bowel and bladder problems, and is as safe for the baby as vaginal delivery.
The National Institutes of Health (NIH) and American College of Obstetricians (ACOG) agree that a doctor's decision to perform a c-section at the request of a patient should be made on a case-by-case basis and be consistent with ethical principles. ACOG states that "if the physician believes that (cesarean) delivery promotes the overall health and welfare of the woman and her fetus more than vaginal birth, he or she is ethically justified in performing" a c-section. Both organizations also say that c-section should never be scheduled before a pregnancy is 39 weeks, or the lungs are mature, unless there is medical need.
Most c-sections are unplanned. So, learning about c-sections is important for all women who are pregnant. Whether a c-section is planned or comes up during labor, it can be a positive birth experience for many women. The overview that follows will help you to know what to expect during a nonemergency c-section and what questions to ask.
Cesarean delivery takes about 45 to 60 minutes. It takes place in an operating room. So if you were in a labor and delivery room, you will be moved to an operating room. Often, the mood of the operating room is unhurried and relaxed. A doctor will give you medicine through an epidural or spinal block, which will block the feeling of pain in part of your body but allow you to stay awake and alert. The spinal block works right away and completely numbs your body from the chest down. The epidural takes away pain, but you might be aware of some tugging or pushing. (See managing labor pain for more information). Medicine that makes you fall asleep and lose all awareness is usually only used in emergency situations. Your abdomen will be cleaned and prepped. You will have an IV for fluids and medicines. A nurse will insert a catheter to drain urine from your bladder. This is to protect the bladder from harm during surgery. Your heart rate, blood pressure, and breathing also will be monitored. Questions to ask:
The doctor will make two incisions. The first is about 6 inches long and goes through the skin, fat, and muscle. Most incisions are made side to side and low on the abdomen, called a bikini incision. Next, the doctor will make an incision to open the uterus. The opening is made just wide enough for the baby to fit through. One doctor will use a hand to support the baby while another doctor pushes the uterus to help push that baby out. Fluid will be suctioned out of your baby's mouth and nose. The doctor will hold up your baby for you to see. Once your baby is delivered, the umbilical cord is cut, and the placenta is removed. Then, the doctor cleans and stitches up the uterus and abdomen. The repair takes up most of the surgery time. Questions to ask:
You will be moved to a recovery room and monitored for a few hours. You might feel shaky, nauseated, and very sleepy. Later, you will be brought to a hospital room. When you and your baby are ready, you can hold, snuggle, and nurse your baby. Many people will be excited to see you. But don't accept too many visitors. Use your time in the hospital, usually about four days, to rest and bond with your baby. C-section is major surgery, and recovery takes about six weeks (not counting the fatigue of new motherhood). In the weeks ahead, you will need to focus on healing, getting as much rest as possible, and bonding with your baby—nothing else. Be careful about taking on too much and accept help as needed. Questions to ask:
Some women who have delivered previous babies by c-section would like to have their next baby vaginally. This is called vaginal delivery after c-section, or VBAC. Women give many reasons for wanting a VBAC. Some want to avoid the risks and long recovery of surgery. Others want to experience vaginal delivery.
Today, VBAC is a reasonable and safe choice for most women with prior cesarean delivery, including some women who have had more than one cesarean delivery. Moreover, emerging evidence suggests that multiple c-sections can cause serious harm. If you are interested in trying VBAC, ask your doctor if you are a good candidate. A key factor in this decision is the type of incision made to your uterus with previous c-sections.
Your doctor can explain the risks of both repeat cesarean delivery and VBAC. With VBAC, the most serious danger is the chance that the c-section scar on the uterus will open up during labor and delivery. This is called uterine rupture. Although very rare, uterine rupture is very dangerous for the mother and baby. Less than 1 percent of VBACs lead to uterine rupture. But doctors cannot predict if uterine rupture is likely to occur in a woman. This risk, albeit very small, is unacceptable to some women.
The percent of VBACs is dropping in the United States for many reasons. Some doctors, hospitals, and patients have concerns about the safety of VBAC. Some hospitals and doctors are unwilling to do VBACs because of fear of lawsuits and insurance or staffing expenses. Many doctors, however, question if this trend is in the best interest of women's health.
Choosing to try a VBAC is complex. If you are interested in a VBAC, talk to your doctor and read up on the subject. Only you and your doctor can decide what is best for you. VBACs and planned c-sections both have their benefits and risks. Learn the pros and cons and be aware of possible problems before you make your choice.
