Vaginal Birth After Cesarean Section
(VBAC; Trial of Labor after Cesarean [TOLAC])

Reasons for Procedure
- Unsuccessful VBAC—Some women attempting VBAC require a repeat C-section. Most often, this is due to fetal distress during labor and failure to progress during labor. This may be caused by ineffective labor contractions.
- Uterine rupture—This rare but life-threatening condition occurs when the uterus tears along the prior C-section scar. This is due to poor healing of the prior uterine incision. An emergency C-section is performed in this situation.
- Uterine infection
- Tear of tissue around the vagina
- Complications requiring forceps or vacuum extraction
- Injury to the baby
- Type of previous uterine incision—This may influence your risk of the uterine scar tearing during VBAC.
- Reason for prior C-section—The chances of having a successful VBAC are lower for women who had a prior C-section for a reason that could recur with their next labor and delivery. Reasons include a difficult labor and the cervix not opening fully.
- Number of prior C-sections—A higher number of prior C-section deliveries decreases the likelihood for a successful VBAC, because the uterine wall has been weakened.
- Large baby or a baby in the wrong position inside the womb
- Induced labor—Some labor-inducing drugs can increase the risk for uterine rupture. Because of this, your doctor may advise against a VBAC if you require these drugs.
- Mother’s health—Conditions like diabetes , heart disease , and high blood pressure increase the risk of complications.
What to Expect
Prior to Procedure
- Be sure to go to all prenatal care visits with your doctor.
- Eat nutritiously and drink plenty of fluids.
- Get as much sleep as possible.
- Read about giving birth and take a childbirth class.
- Choose a support person to be with you during labor and delivery.
- Write a "birth plan" that explains what you want and helps you to think about possible complications.
Talk to your doctor about:
- Ways to contact her after hours and when you should call
- Steps you should take when in labor
- Whether you want pain relief during labor
- Perineal massage—The perineum is the area between the anus and the vagina. Massaging this area may help to reduce your chance of trauma to the area.
- How you will travel to the hospital
- Arrangements for home and work
Be aware of the signs of labor, which include:
- "Water breaks" (amniotic fluid that surrounds the baby leaks out through the vagina)
- Back pain
- Slight vaginal bleeding
Pain medicines by IV or intramuscular injection:
- Given when contractions become stronger and more painful
- Can cross into the baby's bloodstream
- Injected near spinal cord
- Given in small amounts by an anesthesiologist (a doctor who specializes in anesthesia)
- Drug does not cross into baby's bloodstream
- Decreases pain and feeling in your lower body
- Provides good pain relief and allows you to continue with delivery
- Can cause headaches after delivery and drop in blood pressure, as well as changes in baby's heartbeat
- Injected into spinal fluid
- Used for pain relief during delivery, especially if forceps or vacuum extraction is needed
- Often used for C-section
- Numbs lower half of the body and reduces your ability to push
- Provides good pain relief and works quickly
- Can cause headaches and drop in blood pressure, as well as changes in baby's heartbeat
- Injected into vagina or surrounding area
- Used if an episiotomy (cutting near the vagina) is needed
- Also used when vaginal tears are stitched
- Does not relieve pain of contractions during labor
- Causes you to be asleep during delivery
- Rarely used for routine vaginal deliveries
- Often used for C-sections or emergencies

Immediately After Procedure
- Stitches if the perineum is cut or torn

- Cleansing of the vaginal area, perineum, and rectum
- Ice pack to soothe and decrease swelling of the perineum
- A shot of oxytocin (Pitocin) to help decrease bleeding
- Pain medicines
How Long Will It Take?
How Much Will It Hurt?
Average Hospital Stay
- Sore breasts—Your breasts may be painfully engorged when your milk comes in. Also, your nipples may be sore.
- Constipation —You may not be able to move your bowels until the third or fourth day after delivery.
- Stitches may make it painful to sit or walk.
- Hemorrhoids —Hemorrhoids are common. They may make it painful for you to move your bowels.
- Hot and cold flashes—This is due to your body trying to adjust to the change in hormones and blood flow levels.
- Urinary or fecal incontinence—During delivery, your muscles were stretched. This may make it hard for you to control your urine and bowel movements.
- "After pains"—The shrinking of your uterus can cause contractions. These can worsen when your baby nurses or when you take medicine to reduce bleeding. It is normal to have this after delivery.
- Vaginal discharge—This is heavier than your period and often contains clots. The discharge gradually fades to white or yellow and stops within two months.
- Weight—Your postpartum weight will probably be about 10 pounds below your full-term weight. Water weight drops off within the first week as your body regains its salt balance.
- "Baby blues"—About 80% of new moms have irritability, sadness, crying, or anxiety . This begins within days or weeks of giving birth. These feelings can result from hormonal changes, exhaustion, unexpected birth experiences, adjustments to changing roles, and a sense of lack of control over your new life.
- Postpartum depression (PPD)—This condition is more serious and happens in 10%-20% of new moms. It may cause mood swings, anxiety, guilt, and persistent sadness. Your baby may be several months old before PPD strikes. It is more common in women with a personal or family history of depression.
- Postpartum psychosis—Postpartum psychosis is a rare, but severe condition. Symptoms include difficulty thinking and thoughts of harming the baby. If you feel this way, call your doctor right away.
- Sexual relations—You may not feel physically or emotionally ready to begin sexual relations right away.
- When your baby sleeps, take a nap.
- Set aside time each day to relax with a book or listen to music.
- Shower daily.
- Get plenty of exercise and fresh air.
- Schedule regular time for you and your partner to be alone and talk.
- Make time each day to enjoy your baby. Encourage your partner to do so, too.
- Breastfeeding is encouraged unless your doctor tells you otherwise.
- Clean less and have easier meals. Take a break from having visitors if you feel stressed.
- Ask for help when you need it.
- Talk with other new moms and create your own support group .
- Delay having sexual intercourse and putting any objects in the vagina until you have had your six-week check-up.
- Be sure to follow your doctor's instructions .
