The Case Against Valsalva Pushing in the Second Stage of Labor

The-Case-Against-Valsalva-Pushing-in-the-Second-Stage-of-Labor

Natural childbirth is as old as time itself…if it weren’t, none of us would be here! For most of human history, childbirth has been the purview of women, mostly midwives and female relatives, who assisted a laboring mother as she did what comes naturally.

However, shortly after World War II, that all changed as modern medical intervention hijacked childbirth and turned it into a medical condition, subverting the natural biological process and placing it in the hands of mostly male physicians.

As more and more women began giving birth in hospitals, much was lost in terms of spontaneity during labor, and expectant mothers became patients, with all the implications that medical meddling brings with it. In effect, women gave up their rights to manage how they gave birth, and allowed themselves to be subjected to the whims and commands of medical personnel.

Second-Stage Labor Pushing and Perineal Tearing

One unfortunate and unnecessary outcome of medical childbirth is perineal tearing, often a consequence of second-stage labor pushing, where the mother is encouraged to bear down as hard as possible once the cervix is fully dilated. Called Valsalva pushing, this approach was adopted to shorten the second stage of labor, purportedly to reduce health risks to the baby.

With forced pushing, tearing to the perineum can be severe, sometimes leading to incontinence and even lifelong nerve problems that sometimes do not manifest until after menopause. In many cases, an episiotomy is performed routinely to make a clean incision that is easier to repair than a ragged tear. However, recent research reveals that perineal tearing is much less likely to occur when the mother is not encouraged to push, allowing natural childbirth to take its course.

One study by Kelly et a. (2010) found that delaying pushing for 90 minutes after full cervical dilation actually shortened the time of labor significantly, by a margin of 51%, with no significant increase in overall time for the second stage of labor.

Changing the Way Mothers Labor

One reason perineal tearing became common during medical childbirth is that for decades women were confined to bed, to labor on their backs. Yet prior to the 1950s, women were encouraged to change positions by standing, leaning, or kneeing. Using alternative postures during labor often facilitates childbirth while reducing stress and discomfort to the mother.

Now, new guidelines by the by the Royal College of Obstetricians and Gynaecologists (RCOG) and the Royal College of Midwives in the UK discourage pushing during the second stage of labor and encourage alternative postures, along with breathing through contractions and letting the body and gravity help move the baby through the birth canal. The guidelines also discourage pulling the baby by the shoulders as it can put more pressure on the mother’s perineum.

Physical Therapy for Pre- and Post-Partum Care

Women in peak physical condition are likely to have easier and safer experiences during labor and delivery, and to recover more quickly. Working with a physical therapist can help you get your body ready for a safe and beautiful childbirth experience by stabilizing your pelvis and strengthening the muscles of your pelvic floor.

The women’s health professionals at NYDNRehab can assist you in obtaining optimal health in preparation for childbirth, and after the baby is born.
