One of the most important healthy birth pratices Lamaze promotes is: Avoid giving birth on your back and follow your body’s urges to push.

In today’s world of modern obstetrics, women are conditioned to give birth on their backs.  At the hospital, they are admitted to a labor room where everything is arranged around a birthing bed as the focal point.  Other than a rocking chair, there often is no other furniture or equipment that encourages the laboring woman to be out of bed and utilizing various positions for giving birth.

The media reinforces the idea that birth happens while lying on one’s back.  Try to recall the “births” you’ve watched on television dramas and sitcoms.  How many times have you seen a woman portrayed as being anywhere but in bed, reclining on her back, during labor and birth?  Most young women who will give birth in 2010 have never seen birth in an upright position.  Childbirth educators, rather than being able to correct the misconception that birth is best on one’s back, are often constrained by having to teach methods and procedures with which the obstetricians and hospital policy makers want their patients to comply.

What difference does it make, though, if a woman gives birth on her back?  It’s pretty much the way we’ve done it–at least in hospitals–for the last 100 years or so.  And why follow your body’s urges when it comes to pushing?  Wouldn’t most women rather start pushing as soon as they are completely dilated, and labor over with sooner?

There are many disadvantages to giving birth on your back.  Among them are:

  • Increased risk of perineal tearing and trauma (1)
  • Increased vulvar edema (swelling of the genitals after birth, which is painful and makes it difficult to urinate, sometimes necessitating a urinary catheter) (1)
  • Increased risk of fetal intolerance of contractions(2)
  • The laboring woman is pushing “uphill” against gravity. as the birth canal angles upward from the small of the back to the vaginal opening

Some providers pride themselves on “allowing” the laboring woman to push while in a semi-sitting position.  While this position does utilize gravity, there are still disadvantages.  One study showed that, compared to women who were in a kneeling or hands-and-knees position during labor, women who were sitting experienced increased pain, feelings of exposure, and vulnerability.(3)

Another study found that there was a higher rate of severe lacerations when the woman gave birth in a sitting position.  While the rates were not statistically significant, this result makes sense to me.  The tailbone is normally flexible.  When a woman sits on her buttocks to give birth, the tailbone’s flexibility is limited.  Rather than the tailbone being able to flex and expand the pelvic opening, the baby’s head is pushed directly into the perineum and upward toward the clitoris.  While I am not aware of research that specifies the location of lacerations that occur with various birth positions, it has been my personal experience that clients giving birth in a sitting position experience more tears around the urethra, clitoris, and inside the labia.  These tears are often more difficult and painful to repair than a perineal laceration.

What are the advantages of spontaneous pushing, rather than directed pushing?  Although many providers firmly believe that the “take a deep breath, hold it, and push as hard as you can to the count of ten” style of pushing is essential to a shorter second stage of labor, research does not support this belief.(4)  On the contrary, women who are not coached regarding how and when to push will spontaneously begin to bear down with short pushes, exhaling as they push, rather than holding the breath.  As the baby’s head moves down, women’s pushing efforts often become stronger and more prolonged, but typically will include several short pushes per contraction rather than three long pushes.  Finally, as the head begins to crown, most women feel the “ring of fire”, the burning sensation in the perineum, and instinctively hold back.  This instinctive reaction has the benefit of allowing the skin of the perineum to stretch slowly, avoiding tears.  Modern obstetrics coaches women at this point to do exactly the opposite of what their instincts tell them: “push through the pain!” “get mad at the pain and push it out!” “take a deep breath and push as hard as you can!”  These instructions cause more rapid delivery of the baby’s head, increasing the risk of lacerations.   

Rather than checking a woman’s cervix and telling her she can or can’t push yet, I prefer to simply offer support and encourage the laboring woman to follow her body’s cues.  The old belief that allowing the woman to push before she’s fully dilated will cause swelling of the cervix is out of date.  When a woman says she has the urge to push, I tell her to go ahead and push if she feels like it.  I’ve noticed that when the cervix is not ready for pushing, the woman will not consistently push with the contractions, or will hold back because it is more painful.  However, when the cervix is ready for pushing, even if it is not fully dilated, the woman will push spontaneously with her contractions, and will usually report that pushing is a relief.  This method is so easy to use, and doesn’t require a woman with a strong urge to push to pant and blow for a long period of time before she is allowed to follow her natural intincts.  Following this method, I’ve never had a problem with cervical swelling. 

Woman who are supported in pushing when they choose, in the position of their choice, seem much calmer during the second stage of labor.  I think of Carolina, a young woman having her second baby.  She had had a rapid labor with her first child, and despite the fact that the baby was descending down the birth canal quickly, Carolina was urged to “push harder! push! push! push!”   She felt frantic and out of control, and did not want to repeat the experience.  During her second labor, she shared with me her desire to try to breathe normally through her contractions, until her body took over–and that’s exactly what she did.  When she experienced the first urge to push, I noticed a very slight change in the rhythm of Carolina’s breathing at the peak of a contraction.  The room was quiet, except for the soothing music she had chosen, and the soft sound of her  breaths.  Carolina was bearing down gently with her contractions for several minutes, then made eye contact with me and said, “The baby’s coming”.    I couldn’t see anything, as she had her hand covering her perineum, but moments later, the baby’s head was out.  One more push, and the rest of the baby was born into Carolina’s waiting hands.  She smiled at me, “That was so much better than being yelled at to push!” 

Birth doesn’t have to be a panicked, pressured event.  It can be calm and peaceful, especially when women are supported in spontaneous pushing and choosing their own birth position.
