80-95% of women today get an epidural. They are so common that most hospitals include them in their standard billing for all vaginal deliveries.
I am not against epidurals. I have had two, one with each of my previous births. They definately have their purpose and place. However, I do not think women are educated enough about them to make an informed decision regarding getting an epidural. I believe getting an epidural has become a cultural norm along with many other birth related practices.
Do you know what is in your epidural? I don't think most women do. I sure didn't! I was never told what medication I was being given and what the side effects of those medications were. The assumption I had was that they give them all the time it must be safe.
Lets explore the epidural together. An epidural is a regional anesthetic agent with a narcotic and/or antihypertensive. Caine-derivative anesthetics used in epidurals. Caine derivatives block nerve impulses and anesthetize blood vessels, causing them to relax and dilate. An epidural is normally a combination of three of these types of drugs. One of the three is a slower acting one; Bupivacaine, which lasts about 1 1/2 to 3 hours. The other two are
Chloroprocaine, which lasts from 40-60 minutes and
Lidocaine, which lasts from 60-75 minutes. Novocaine and cocaine are the two Caine-derivative drugs we are most familiar with. Epidural dosages fall somewhere between these two extremes.
Additional drugs may also be combined with the Caine-derivative anesthetics. In certain cases a vasoconstrictor, Epinephrine, is added to prolong the absorption of the main drugs. Sometimes an opium derivative narcotic is added to prolong the pain relief. These may include Fentanyl and Morphine. A side effect to some of these drugs is blood pressure changes in the mother. To counteract these changes an antihypertensive drug, Cloridine, is added.
All dosages are determined by the mother's weight. Sometimes the drugs are administered once, repeated, or in a continues drip. One side effect of medication during pregnancy and/or delivery is the possibility that it will cross the placenta and be administered to the baby. In The Physician's Desk Reference (PDR), a well-respected guide to all drugs, their usage, cautions, and side-effects, states the following about Caine derivatives used in epidurals:
"Local anesthetics rapidly cross the placenta (by passive diffusion) and when used for epidural blocks, anesthesia can cause varying degrees of maternal, fetal, and neonatal toxicity. Adverse reactions in the mother and baby involve alteration of the central nervous system, peripheral vascular tone, and cardiac function."
The PDR lists the possible maternal side effects for Caine derivatives: "Hypostension, (low blood pressure: harmful to the baby) urinary retention, fecal and urinary incontinence, paralysis of lower extremities, headache, backache, septic meningitis, slowing of birthing, increased need for forceps or vacuum delivery, cranial never palsies, allergic reations, respiratory depression, nausea, vomiting, and seizures." As well as increased risk of cesarean deliveries and episiotomies. 70% of women experience side effects. Some very rare, but possible risks of epidural include: trauma to nerve fibers if the epidural needle enters a nerve and the injection goes directly into that nerve; a drug overdose resulting in profound hypertension with respiratory and cardiac arrest and possible death; and central nervous system toxicity resulting from an injection directly into the epidural vein.
Considering the weight of the mother and the weight of the baby, it is possible that the baby will receive an overdose. After the baby is born it must metabolize these drugs, partly through it's liver. The liver of a newborn is immature, metabolizing these drugs increases the likelihood and severity of
newborn jaundice.
Other side effects in the infant may include: lowered neurobehavioral scores, decrease in muscle tone and strength, lowered sucking ability, respiratory depression, increase in fetal heart rate variability, increased need for forceps, and vacuum.
In a previous post I spoke about how one medical intervention creates a chain reaction. An epidural is one of those medical interventions. When you are given an epidural you face the possibility of having continuous fetal monitoring (this limits your mobility, which increases your birthing time as well as increases your risk of c-section. I may talk about this more later), IV, use of additional drugs, bladder catherterization, frequent blood pressure monitoring, continuous administration of oxygen, and forceps, vacuum extraction, and episiotomies. Epidurals can prolong birthing, leading to the possible need to augment the birthing time with
Pitocin.
Learning about why we tend to experience pain during child birth can help to change our attitudes about the need for routine epidurals. Natural child birth is possible. Because of my exposure to
Hypnobabies I have realized that you don't have to experience any pain or discomfort during childbirth. It's not about dealing with pain, but relaxing yourself and giving yourself confidence in your body's ability to birth your baby so that no pain is felt at all.
