A Breech Version May Avoid A First Cesarean Or Lead To A VBAC

12 Nov

A breech is one of the main reasons why women have a cesarean.  Yet it is also one of the most preventable.

With a prior cesarean and a low-transverse uterine scar (bikini incision),  an expectant mother with a breech who wants to have a VBAC  can ask her care provider about the option of an external version.

The current ACOG guidelines for VBAC state that an external cephalic version (ECV) is an option for low risk women with a low transverse uterine scar. If the ECV is successful women can labor for a VBAC rather than schedule a repeat cesarean.

Towards the end of pregnancy, most babies will align themselves in the uterus into a head down position, the safest position for birth. However, in approximately 3-4% percent of pregnancies, the baby will present as a breech, with its feet or buttocks positioned close to the birth canal.

External cephalic version (ECV), also known as a breech version, is a procedure in which external manipulation is used to change a fetus from a breech presentation to a vertex (head down) presentation.

External version is a relatively safe and successful procedure for most women when performed by experienced caregivers. About 65% of breech versions are successful. Complications from ECV are rare.

ECVs are more successful with an experienced care provider. Other factors such as the position of the baby and the level of amniotic fluid also play a role.

According to U.S.  birth data, in 2006 about 73 percent of ECVs were reported as successful. Women who had a successful ECV were more likely to have a vaginal delivery (77.7 percent) than women with a failed ECV (10.4 percent).

Preparing For  ECV

Before doing an ECV most care providers will want to do an ultrasound exam to see the position of the baby, locate the umbilical cord and placenta, and determine the amount of amniotic fluid.  Ultrasound is often used during the procedure. An electronic fetal heart monitor is used to measure the baby’s heart rate before and during the procedure. To make sure the baby’s heart rate has stabilized monitoring usually continues for about 30 minutes after. It is normal for the baby’s heart rate to increase while it is being moved. If the baby does not tolerate the procedure it will be stopped.

Care providers sometimes offer the mother a drug such as terbutaline to relax the uterine muscles, reduce contractions, and facilitate the breech version. Tocolytic drugs do have side effects for both mother and baby and women should find out what they are.

Mothers may be offered the option of having epidural anesthesia and should ask about the benefits and risks of an epidural for this procedure. If a woman has Rh-negative blood she will be offered Rh immune globulin to prevent incompatibility should her blood and her baby’s come into contact during the version. This happens in about 4.1% of external versions.

How A Breech Is Turned

To facilitate the movements of his hands over the mother’s abdomen, her care provider will rub a lubricant on her belly. With both hands on her abdomen, he will place one hand on her belly where her baby’s head would be and the other on the baby’s bottom. He will lift the baby’s bottom with one hand and gently push the head down with the other, backward or forward.

If the procedure is successful the expectant mother will likely go home. It is possible to have this procedure done again if the baby could not be moved into a head-down position. Some women find this procedure uncomfortable and sometimes painful.  Although complications are rare, after the procedure, her care provider should give her information about possible complications that may develop such as vaginal bleeding, going into labor, or the early rupturing of the bag of waters.

Studies show that with a breech version mothers are more likely to have a vaginal birth.

There are specific techniques through fetal positioning to help a baby in utero turn from a breech to a cephalic position (head down). Sometimes this method works and mothers can avoid an ECV.

Few hospital-based care providers today are skilled at attending a breech vaginal birth and many worry about malpractice liability. There is a growing interest, however in supporting women who choose to have a breech vaginal birth given that the evidence supports breech vaginal birth in specific circumstances.

The Power To Push Campaign Has It Right When It Comes To VBAC

5 Oct

The Power to Push Campain was created in 2010 by the British Columbia Women’s Hospital and Health Center to  reduce cesarean rates and help women make informed decisions about VBAC, elective primary or repeat cesareans.

Based on the latest evidence and respect for women’s ability to make their own decisions about how best to give birth, the Power To Push project has developed  well balanced, easy to understand consumer education booklets that tell it like it is. Resources in five different languages include brochures on VBAC, vaginal breech birth, and ECV, external cephalic version, a safe method of turning a breech around the 37th week of pregnancy. Their website also includes videos featuring real women sharing their personal birth stories and wisdom. Theresa’s VBAC story is honest, encouraging, and unusual given that her OB encouraged her to consider a VBAC. Women can also take the Birthing Misconception Quiz to increase their knowledge about cesarean and VBAC.

At the hospital’s Best Birth Clinic, women can be referred to the Choices in Childbirth Counselling Service where women can meet with a Registered Clinical Counsellor to discuss their concerns, and receive current, evidence-based information on the risks and benefits of cesarean birth.

Everyone involved in the Power To Push Campaign is committed to supporting women’s choices and helping them have the best birth possible. The U.S. can certainly benefit from this exemplary model of care aimed at reducing cesareans and increasing access to VBAC.
