How to Make a Surgical Birth a Great Experience
Q. I had a cesarean with our last baby, and I'm worried I might need to
have one again. Am I at higher risk for having another cesarean?
A. The main reason for sentencing a first-time cesarean mother to life-long
birthing in the operating room was the fear of uterine rupture. Years ago,
cesarean incisions were made vertically, in the upper part of the uterus -- the
area most prone to rupture. Nowadays, most cesarean incisions are made
horizontally, in the lower part of the uterus (even in emergencies). This cut,
a low-transverse incision or "bikini cut," is unlikely to rupture. With a low-
transverse incision, authorities now estimate the risk of uterine rupture in
subsequent labors to be around 0.2 percent, which means there is a 99.8 percent
chance of mother going through a labor without rupturing her uterus. In a
survey of 36,000 women attempting VBAC (vaginal birth after cesarean, pronounced
Vee-back), no mother has died of uterine rupture, regardless of the type of
prior uterine incision. In a study of 17,000 women attempting VBAC, no infants
died as a result of uterine rupture. (Don't let the term rupture scare you --
it does not mean that your uterus will suddenly explode. Instead, the first
cesarean scar gradually pulls apart. Fortunately, uterine rupture can be
suspected by electronic fetal monitoring.) So the numbers are greatly in your
favor -- having a VBAC is of negligible risk to you and your baby and certainly
less risky than a surgical birth.
Whether you are a candidate for a VBAC may depend upon the reasons for your
previous cesarean. If you needed a surgical birth because your baby was in a
breech position, you had an active herpes infection, you had toxemia, or the
baby was experiencing true fetal distress, there is no reason to expect you will
need a cesarean again. These factors were unique to the earlier pregnancy and
may not recur. If the diagnosis leading to your previous cesarean was
"cephalopelvic disproportion" (CPD) -- your baby's head was thought to be too
big to pass through your pelvis, there's still no reason to worry. New studies
show that this diagnosis does not lessen your chances of having a VBAC. True
CPD is very uncommon, and in most instances the births could just as easily have
been labeled "failure to progress." Studies report a 65-70 percent chance of
successful VBAC despite a previous diagnosis of CPD. A woman's pelvic outlet
often becomes more flexible with each delivery, and various changes of position
during labor can make it easier for baby to find the way out.
Q. I had a previous cesarean and I haven't yet gotten over feeling that
I was a failure. I'm afraid this will affect my next birth and I'll have
another cesarean.
A. You are no less a woman if you had a cesarean. After all, you nourished
this baby through pregnancy, and your baby grew in your womb, even though the
exit was not the one you planned on. Medical circumstances beyond your control
may have led to your previous surgical birth. In all likelihood, you were doing
the best you could at the time.
This time around you can avoid feelings of regret by being informed and
prepared, and following the suggestions we have given throughout this book on
having a healthy pregnancy and efficient delivery. In our experience, women who
begin studying up for a VBAC often realize that there were things they could
have done to lessen their chances of having the cesarean. Mothers who can
satisfy themselves that they did all they could to influence a positive birth
outcome typically do not experience feelings of guilt and failure, because they
realize they had a truly necessary cesarean.
Truthfully, you are not guilty for what happened to cause a cesarean. This
is easy to see when you know you didn't "bring on" a breech position, a cord
tightly wrapped around your baby's neck, a multiple pregnancy, or even an active
case of herpes. Your most likely reaction would be "Thank God for modern
obstetrics." Yet if the situation is less clear cut, no concrete physical
reason you can point to, it would be easier to need to cast blame. If there is
some doubt as to your performance ("I didn't walk enough," "I took the drug too
soon," "I didn't relax enough" and on and on the list could go) the easiest
person to blame would be yourself, and you would feel loaded with guilt. But
that is hardly realistic. In many ways you are the victim in the scenario.
Resolve in your mind that you did the best you knew how and blame the system if
that helps. Move on from there to forgiveness and the resolve to learn from the
past -- perhaps the greatest gift of all next to your precious baby.
Q. Could my baby be less healthy if delivered by cesarean rather than
vaginally?
A. Your baby should not be any less healthy if delivered by cesarean. In
fact, depending on why the cesarean is done, he could turn out to be healthier.
If a baby is found to be in distress during labor, waiting for a vaginal birth
could compromise his health. Cesarean-birthed babies do often display the
picture book round newborn head when compared to the typical "conehead" of a
baby who worked his way through the narrow vaginal passage. Surgically birthed
babies do sometimes require more suctioning right after birth. They tend to be
a bit more mucusy, probably because fluid was not squeezed out of the lungs, as
it would have been in vaginal birth. Cesarean-birthed babies are sometimes
slower to breastfeed, which may be more a result of mother and baby being
separated and the drugs used in labor.
One possible health complication from cesareans is when a baby is delivered
too early. This may happen when a section is performed before the mother goes
into labor, perhaps because she is diabetic or has a heart problem. The due
date may suggest that the baby is mature enough to be born, when in fact he
wasn't ready. If there is uncertainty about your dates or the maturity of your
baby, and you need a pre-scheduled cesarean, your doctor may elect to do
ultrasound and tests on the maturity of the baby's lungs to be sure she is ready
for life outside the womb. If there is any doubt and there is no reason to
suspect baby is in jeopardy by being in the womb a week or so longer, it is best
to wait. There are benefits and risks of not doing a cesarean until mother
begins labor. But, you may think, why should I go through any labor if I'm
going to have a cesarean anyway? Besides indicating the baby is ready to be
born, contractions give baby and mother the benefit of the natural hormones of
labor, endorphins . Studies show that babies
delivered by cesarean after mother has labored a while have fewer breathing
problems in the first few days after birth than those whose mothers never
entered labor. On the other hand, the surgical complication rate for mother may
be slightly less for a scheduled cesarean than when the surgery has to be done
because of a complication during labor. When in doubt, best not to hurry baby
out.
Q. So many women are having cesareans nowadays. It seems to be no big
deal. What complications might happen?
A. True, with modern surgical techniques and better anesthesia, cesarean
sections have never been safer. Yet a surgical birth is a big deal. Cutting
through all the layers of your abdomen and into your uterus is major surgery.
Though minimal, there are risks of complication such as hypersensitivity to the
anesthetic, excessive bleeding, post-operative infection, and pain. Also, you
are required to do double duty: healing yourself while learning to care for a
newborn. Not the most joyful way to enter motherhood. Best to do what you can
to lessen your chances of needing a surgical birth.
Q. My due date is almost here and my baby is still butt-down in the
breech position. My doctor says it's safest for my baby to be delivered by
cesarean. Is a cesarean necessary, or are there alternatives that are just as
safe?
A. Studies show that breech babies have a lower risk of birth injury and
newborn complications if delivered surgically rather than vaginally. Hence, the
trend toward cesareans for babies in the breech position. Some specialists
wonder whether the statistical increase in complications with vaginal delivery
could be related to the breech position itself rather than to the mode of
delivery, but presently in most hospitals, from 80 to 90 percent of breech
babies are delivered by cesarean. The main concern in the vaginal delivery of a
breech newborn is that, with the feet or buttocks presenting first, the head
will not have enough time to mold itself to the pelvic canal and may get stuck
once the rest of the body is out. Also, a breech delivery can cause damage to
the major nerves leading to the arms and hands. Both of these complications are
less likely when baby presents buttocks first rather than feet first (frank
breech). Prolapse of the umbilical cord (the cord slips through the cervix
before baby's body and gets pinched), an emergency requiring an immediate
cesarean delivery, is more common in all breech deliveries.Baby's being in the
breech position does not mean you absolutely must have a cesarean birth. The
American College of Obstetricians and Gynecologists officially sanctions vaginal
births for breech babies as safe in selective situations. Your doctor will
weigh the risks of the surgical versus the vaginal birth and recommend the
course of action that is best in your situation.
Q. I had a vaginal herpes outbreak early in my pregnancy, but seem to
be okay now. Will I need a cesarean section because of herpes?
A. A newborn baby can contract herpes during passage through an infected
birth canal, so it is considered prudent obstetrical medicine to deliver all
babies whose mothers have active herpes at the time of delivery via cesarean
section. Herpes infections are life threatening in newborns. If you have
herpes, your doctor may do monthly or weekly vaginal cultures throughout your
pregnancy to monitor your body's response to the stress of pregnancy (stress can
cause genital herpes to flare up). Women with prior herpes outbreaks actually
pass some immunity to their newborns. Women who acquire herpes for the first
time during their pregnancy and have active sores at the time of delivery pose
the greatest risk of infecting their babies. When you begin labor, your doctor
may judge that it is safe for you to deliver vaginally if he or she sees no new
herpes sores. If, however, your vaginal cultures continue to show herpes
throughout your pregnancy, or you have herpes sores when you begin labor, you
will need a surgical delivery.
Q. I'm scheduled to have a cesarean section. I know that in my
situation it's best for my baby, but I'm disappointed. I wanted so much to have
a natural birth. Besides, I'm scared of surgery.
A. It's normal to feel disappointed when the birth you hoped for will not be
the birth you get, but the end result will be the same: you'll see your baby!
A healthy baby is your main goal, even if you will need some technological help.
You have grown this baby inside of you. He or she will be your most important
accomplishment; regardless of what route this special little person takes to get
here.
All the natural childbirth information that is now available to women is
great, yet it does set women up to feel like failures if they have to have
surgery. Remember that a hundred years ago surgical birth was not a safe
option, and be thankful that your cesarean will help ensure your baby's health.
It's nice that you know about the surgery ahead of time so you can cope with the
change of plans and not fight disappointment at the time of birth. You can also
plan ahead and make the birth a positive experience for you and your baby. It
takes maturity and a willingness to set aside your own desires to make the best
of this situation. Having your baby surgically will be no less of an
accomplishment than having a natural birth.
1. Select birth attendants and a birth place friendly to VBAC's.
Be sure both your practitioner and your hospital are up on the latest studies.
The nationwide success rate is around 20 percent. Yet if a mother is under the
care of a practitioner who regards VBAC as no riskier than any other delivery,
the mother delivers in a hospital that does not consider VBAC women "high risk,"
and the mother uses the suggestions for helping the labor progress that are
mentioned below, the VBAC success rate is 75-90 percent. This means that a
mother choosing a VBAC may, in fact, have an even smaller chance of having a
cesarean than the general population. Find out what your prospective birth
attendant's VBAC success rate is. For normal low-risk pregnancies, it should be
at least 70 percent. Shun practitioners and hospitals that try to label you
"high risk" even if you have no risk factors besides a previous section.
Studies show that even mothers with two or three previous cesarean births have a
70 percent success rate with VBAC if they deliver in a birthplace supportive of
VBAC's. Obstetrical centers that specialize in VBAC's do not consider most VBAC
candidates as high risk, and treat them no differently than any other
obstetrical client. In fact, they consider it counterproductive to attach the
"high risk" label to VBAC mothers. Most women wishing a VBAC should be treated
like any other woman delivering a baby. They require no more or less
technology, intervention, or monitoring. Beware especially of birth attendants
who have a "pelvic prejudice" against small-hipped mothers wanting a VBAC. Many
petite women have successfully pushed out big babies.
2. Employ a professional labor assistant. If you're serious about
delivering your next baby vaginally, a PLA is a must. In our
experience, mothers using a PLA were much more likely to have the birth they
wanted.
3. Don't let technology or the measurements it produces scare you.
VBAC studies fail to show any correlation between the size of the baby and the
chances of uterine rupture. Also, estimates of fetal size and weight by
ultrasound are not always accurate, especially in the final month.
4. Join a support group. There are support groups for mothers who
need help in grieving about their previous cesarean or in avoiding another one.
ICAN (International Cesarean Awareness Network) is one of the best, and has
chapters nationwide. This support group will help you deal with feelings of
regret from your previous cesarean while arming you with information on how to
avoid another one. You will hear helpful suggestions from mothers who have gone
the surgical route once and were highly motivated to try a VBAC the next time.
One great piece of advice from this and other support groups is to keep your
mind in your present labor and not allow yourself to have flashbacks from the
labor that led to the cesarean. Otherwise, you may panic at the first monitor
alarm and undo all the good work of a previously efficient labor. If you want
to feel fully empowered for VBAC, a support group is your best bet.
1. Consider the possibility that your baby might turn. Around half of all
babies start out bottom down early in pregnancy. Most turn head-down by 32-34
weeks. If baby hasn't turned by 36 weeks he or she is likely to remain in the
breech position. For some unknown reason, three to four percent of babies never
turn head-down.
2. If your baby hasn't turned on her own by 36-37 weeks, your doctor (or a
specialist you are referred to) can attempt a maneuver called external version,
in which he or she manipulates your abdomen to turn baby into the head-down
position. External version is successful 60-70 percent of the time (40-50% for
first pregnancies), but some babies turn back and require a second attempt. A
few stubborn babies keep reverting to the breech position and remain there. A
version is generally a safe and only mildly uncomfortable procedure, yet
sometimes it can be painful to mother and can cause distress to baby.
3. Another alternative is to search out a doctor who has experience in
vaginal delivery of breech babies. He or she will most likely be affiliated
with a hospital that has the technology and support staffs to properly care for
the baby should a complication occur. We have found that most doctors
experienced in vaginal delivery of breech babies either practice at a university
hospital obstetrical center, or have gray hair and began delivering babies at
least twenty years ago, when over 90 percent of breech babies were delivered
vaginally. You may get discouraged. Many of the doctors who have this kind of
experience are now retired. Since in the past ten years most breech babies have
been delivered surgically, newly trained obstetricians may never even have
witnessed a vaginal breech birth. Also, if the obstetrical standard in your
community is that breech babies are to be delivered surgically, don't be
surprised if your doctor is forced to comply with this standard.
4. Obstetricians and hospital centers with a lot of experience in vaginal
breech deliveries usually follow the American College of Obstetricians and
Gynecologists Guidelines for breech delivery. The criteria you need for a safe
vaginal delivery of a breech baby include: baby is in the frank breech position,
bottom down instead of feet first or legs crossed in tailor sit; baby weighs
between 5.5 and 8 pounds (baby's head getting stuck during delivery is more
likely to occur in small and premature babies, probably because the head is
proportionally larger than the rest of baby's body); baby is mature or at least
older than 36 weeks; baby's head is tucked down, chin on chest, prior to
delivery; mother is judged to have an adequate pelvis as determined by a
technique called the fetal pelvic index; mother's labor progresses normally; and
the hospital facility and staff is equipped for an emergency cesarean within 30
minutes. (Mother having delivered a previous baby vaginally adds another plus
to the okay list.) If your baby is a footling or a complete breech, weighs over
nine pounds, or is premature, your doctor will probably choose to deliver your
baby surgically. Be aware that each specialist is likely to have his or her own
variations on these criteria. Also, remember that an x-ray diagnosis of
"inadequate pelvis" may be inaccurate since your pelvic outlet will enlarge
during delivery, especially in the squatting position.
5. If you wish to have a vaginal delivery of your breech baby and your doctor
feels that you meet the criteria, expect that your labor will be monitored more
closely than most. Even though you will experience careful surveillance during
labor, take special care not to let the fear factor interfere with your labor.
Here's where a professional labor assistant can help, making sure that birth
attendants are not hovering over you "waiting for something to happen."
- Ask your doctor for a spinal or epidural anesthetic so you can be awake for
the birth.
- Have your partner sit next to you at the head of the operating table. If
he's hesitant, remind him that the actual procedure takes place behind a sterile
curtain. He won't see anything upsetting.
- Ask your obstetrician to lift baby high enough so you can see him or her
right after delivery. It is a beautiful sight to see your newborn lifted "up
and out" during a cesarean birth.
- Immediately after your baby is delivered and quickly checked over
(temperature, breathing and pulse, and heart rates are stable) ask that baby be
brought to you to be held and hugged. You may need some help since you may be a
bit groggy and one arm may be immobilized for an intravenous. This mother-
father-baby bonding time, though brief, is an ideal time for pictures, and the
anesthesiologist or attending pediatrician will often act as photographer for
you.
- While your uterus and abdomen are being stitched closed (this takes about 30
minutes) and the operation completed, your husband should accompany baby to the
nursery so he or she will not be alone with strangers. This extra father-baby
bonding time will have a deep impact on both of them.
- To decrease postoperative pain, ask your anesthesiologist about using a
long-acting analgesic given in the anesthetic tubing. This do-it-yourself
analgesia, called "patient-controlled analgesia" (PCA), is set up so you can
administer your own medication through your intravenous. Just turn the pump on
and off, as you need relief. This medication is safe for your breastfeeding
baby.
- In most cases baby can be brought to your bedside within an hour or two of
surgery. If your husband or a nurse is present in the room and baby is healthy,
it's even possible for a cesarean-birthed baby to room in with mother. The best
postoperative "pain reliever" is an "injection" of baby in your arms.
- Be planning ahead for some good long-term help, one thing you'll need more
of since you'll be recovering from major surgery.
