Pitocin and Birth Injuries

Child Birth DeliverWhen the time for a baby to be born finally arrives at the end of pregnancy, the mother's body starts releasing a unique hormone called oxytocin. Oxytocin is what triggers uterine contractions and basically fuels the process of labor and delivery. Pitocin (and Syntocinon) is a synthetic reproduction of the oxytocin hormone. Doctors often dispense Pitocin to pregnant mothers to induce the start of labor by stimulating uterus contractions and/or to accelerate labor and delivery. Pitocin is widely utilized in labor and delivery rooms and can be highly effective when used carefully and responsibly. However, the use of Pitocin to induce or speed up labor often results in overstimulation and fetal distress which increases the risk of birth injury.

What is Pitocin?

Pitocin is an artificial form of oxytocin. Oxytocin is natural hormone released by the pituitary gland and it serves a critical function in the childbirth process. Oxytocin stimulates the muscles of the uterus to contract and start the process of child labor. Oxytocin continues to fuel the labor and delivery process by prompting the body to release prostaglandins which further increases the frequency and intensity of uterine contractions.

Pitocin is a synthetically manufactured form of oxytocin that doctors can administer intravenously. The Pitocin is quickly absorbed into the bloodstream and triggers the same biological reactions in the mother's body as oxytocin. OB-GYNs typically use Pitocin for one of 2 reasons: (1) to induce the start of labor when the baby is overdue; and (2) to stimulate contractions and jump start labor that is not progressing fast enough.

Problems With Pitocin

Pitocin has its critics. Several studies have demonstrated that the use of Pitocin increases the risk of birth injuries and other negative events during childbirth. There are 2 underlying issues with Pitocin that account for this: (1) dosage response; and (2) hyper stimulation.

Administering the proper amount of Pitocin is very problematic because the effects of the drug on women vary dramatically. Some women who receive Pitocin tend to over respond to the drug and start having overly strong and frequent contractions. But in other women the same dose of Pitocin may have little or no effect at all. This problem is often compounded by the fact that once Pitocin is given doctors have no real way of measuring its effect. Adding yet another layer of complication is the delayed reaction time to Pitocin. The effects of Pitocin do not kick in until 30-45 minutes after it is administered. As a result, second doses of Pitocin are often given before the effects of the initial dose can be fully assessed.

The second issue that makes Pitocin so problematic is a potentially dangerous side effect known as hyper stimulation. When oxytocin is overdosed or a woman over responds it has a tendency to hyper stimulate the muscles of the uterus. This type of over stimulation can trigger contractions that are too powerful, too frequent or too long which can overstress the placenta and threaten the health of the baby.

The placenta is a key organ that develops inside the womb and attaches to the wall of the uterus. The placenta is responsible for delivering oxygen and nutrients from the mother to the baby until the baby is born and starts breathing on its own. Each time uterine contractions occur during labor, the placenta gets momentarily compressed and blood flow to the baby is restricted until the contraction subsides. This makes ample rest time between contractions very important because they allow the baby a chance to get oxygen before the next contraction.

Hyper stimulation from Pitocin can result in intense contractions with as little as 2 minutes of rest time in between. This can critically impair the functionality of placenta during labor and restrict oxygen delivery to the baby. Oxygen deprivation during childbirth is extremely dangerous and one of the leading causes of neurologic birth injuries which can result in permanent disabilities like cerebral palsy.

Anecdotally, some women believe that a delivery with a oxytocin enhancer is more painful. This may well be true but there is not medical literature that supports this theory.

Guidelines for Pitocin

The inherent dangers of Pitocin have led to the development of very strict medical guidelines for the appropriate use of the drug. These guidelines instruct that Pitocin should be administered conservatively starting at a very low dose with careful fetal stress monitoring. Once uterine contractions reach a normal pattern no further Pitocin should be given. Finally, if labor is still not progressing even after Pitocin has triggered normal contraction activity doctors should resort to C-section delivery NOT more Pitocin.
