Epidural anesthesia is the most commonly utilized method for pain relief during childbirth. Many women specifically request an epidural over other pain management options, with over 50% of hospital births in the United States involving this technique. As you prepare for your “big day,” it’s beneficial to explore different pain relief options to make informed decisions during labor and delivery. Familiarizing yourself with the various types of epidurals, their administration, benefits, and potential risks will help you navigate your childbirth experience more comfortably.
What is an Epidural?
An epidural is a form of regional anesthesia that specifically targets pain in certain areas of the body. The primary aim of this anesthesia is to provide analgesia, or pain relief, rather than complete anesthesia, which would eliminate all sensation. An epidural works by blocking nerve signals from the lower spinal segments, resulting in reduced sensitivity in the lower half of the body.
The medications used in epidurals belong to a class known as local anesthetics, including options like bupivacaine, chloroprocaine, and lidocaine. These local anesthetics are often combined with opioids or narcotics, such as fentanyl and sufentanil, to enhance pain relief while minimizing the required dosage of local anesthetic. The addition of medications like epinephrine or clonidine can also help prolong the effects of the epidural or stabilize the mother’s blood pressure.
How is an Epidural Administered?
Before active labor begins and prior to placing the epidural, intravenous (IV) fluids will be initiated, typically around 1-2 liters during labor. An anesthesiologist, obstetrician, or nurse anesthetist will perform the procedure. You’ll be asked to arch your back and remain still while lying on your left side or seated, which is crucial for the successful placement of the epidural.
The area around your lower back will be cleaned with an antiseptic to reduce the risk of infection. A local anesthetic will be injected to numb the skin, followed by the insertion of a needle into the space surrounding the spinal cord in your lower back. A small catheter is placed through the needle into the epidural space, after which the needle is removed, leaving the catheter in place to deliver medication either through continuous infusion or periodic injections. The catheter is secured to your back to prevent dislodgment.
Types of Epidurals
There are two primary types of epidurals in use today, and practices may vary among hospitals and anesthesiologists. It’s a good idea to discuss specific practices with your healthcare provider.
- Standard Epidural: Once the catheter is in place, a combination of narcotics and anesthetics is administered either through a pump or via periodic injections. This approach utilizes narcotics like fentanyl or morphine to reduce the amount of local anesthetic required, potentially minimizing adverse effects. You should inquire about your hospital’s policies regarding movement and eating during labor.
- Combined Spinal-Epidural (CSE) or “Walking Epidural”: This technique involves an initial injection of narcotics or anesthetics directly into the intrathecal space, which is the area just below the outer membrane surrounding the spinal cord. This method allows for greater freedom of movement while in bed and enables you to change positions more easily. With the catheter in place, you can request additional epidural pain relief if needed. It’s worth asking about your hospital’s policies on mobility, eating, and drinking after the epidural is administered.
These medications can decrease muscle strength, balance, and reaction times. Typically, a CSE provides pain relief for 4-8 hours.
Benefits of Epidural Anesthesia
- It allows you to rest if labor is prolonged.
- By alleviating discomfort, it can lead to a more positive birthing experience.
- Generally, an epidural enables you to stay alert and actively participate in your delivery.
- If a cesarean section becomes necessary, an epidural allows you to remain awake while still providing effective pain relief during recovery.
- When other coping strategies fall short, an epidural can help manage fatigue, irritability, and exhaustion, allowing you to relax, focus, and gather the strength needed to continue as an active participant in your childbirth journey.
