Using Narcotics for Pain Relief During Labor: Types & Side Effects
Many women end up relying on some type of method to reduce the physical pain of childbirth. As you prepare for labor, it is important to become familiar with the pain medications that are available, how they work, their risks and their benefits.
The method you choose for pain relief will depend on your personal preference, your health care provider’s recommendation, and the availability of medications at your birthing facility.
Opiates are a type of analgesic given to relieve pain. When used during childbirth, opiates are considered the first option after natural methods for pain relief such as labor in water, deep breathing, and massage.
Opiates are given in small doses and usually administered during the early stages of labor in an attempt to avoid potential side effects for both the mother and baby.
What are the advantages of using opiates during childbirth?
Opiates offer pain relief and do not interfere with a woman’s ability to push during labor. Unlike an epidural, an opiate does not numb the pain; it instead helps to take some“edge” off of the pain. Opiates can help reduce anxiety and improve the mother’s ability to cope with painful contractions.
Mothers can experience the following side effects:
Opiates cross the placenta during labor and can produce the following side effects in the baby:
- Central nervous system depression
- Respiratory depression
- Impaired early breastfeeding
- Altered neurological behavior
- Decreased ability to regulate body temperature
For these reasons, your baby might need other medication to counteract the effects of the opiate. Naloxone is a medication given in small doses that can reverse the respiratory depression that opiates can cause in a baby. It is usually given intravenously and its effects can be seen within a few minutes and can last up to 2 hours.
The most frequently used narcotic medications are:
Demerol is a popular choice for pain relief during labor. Demerol alters how the mother recognizes the pain she is experiencing by binding to the receptors found in the central nervous system.
The advantages of Demerol include:
- Can be given by injection into the muscle, the vein or by a Patient Controlled Analgesia (PCA) pump
- Fast acting – starts working in less than 5 minutes
Demerol can cause drowsiness, nausea, vomiting, respiratory depression, and maternal hypotension (low blood pressure). If injected within 2-4 hours of delivery, Demerol has been found to cause breathing difficulties in some babies.
In recent years, morphine has not been routinely used as a method of pain relief during labor because it has been found to depress the baby’s ability to breathe.
Stadol has been found to relieve pain when given in the first stage of labor. This narcotic is considered more potent than Demerol. It is usually given intravenously in small doses, usually 1 to 2 mg.
The advantages of using Stadol include:
- Starts working in less than five minutes
- Is a sedative
- Has minimal fetal effects
- Causes minimal nausea
Stadol can cause the mother to have respiratory depression, dizziness, and dysphoria (a state of feeling unwell and unhappy). Stadol can cause respiratory depression in the baby.
Fentanyl is a synthetic opiate that provides mild to moderate sedation. The advantages of using Fentanyl include:
- Begins working quickly (although, usually only lasts 45 minutes)
- Minimal sedation
- Minimal fetal effects
You and your baby can experience some sedation and/or nausea. According to Danforth’s Obstetrics and Gynecology, babies born to mothers who used Fentanyl to relieve pain during labor were less likely to need naloxone (medication to help with breathing) than babies born to mothers who used Demerol.
Nubain is an opiate agonist-antagonist comparable to morphine. The advantages of using Nubain include:
- Begins working within 5 minutes of administration
- Minimal nausea
- Minimal fetal effects
Nubain can cause the mother to have sedation and dysphoria (a state of feeling unwell and unhappy).
Medication can be given in any of the following ways:
- A one-time injection into the spinal column.
- IV or Intravenous placement into a vein on the back of the hand or arm. A needle is inserted into a vein with a plastic tube connected to a bag holding fluid that slowly drips into your body. In a hospital setting, an IV is usually placed to help you stay hydrated throughout labor and ensure access to medications if they are needed.
- Patient Controlled Analgesia (PCA) pump is a way that a mother can control doses of pain medication during labor by pushing a button. The advantage of having a PCA is that it can give a mother an increased sense of control, and the mother does not have to rely on a nurse to bring pain medication. Fentanyl and Demerol are common narcotics that can be given using a PCA pump. The pump is pre-programmed to provide dosages small enough to relieve pain without releasing too much medication.
