Labor and delivery: Pain medications
Epidural block
Description
An epidural block is a regional pain-blocking procedure that can be used during labor. An epidural block uses one or more pain medications called anesthetics injected via a catheter into a small space outside the spinal cord in the lower back (epidural space). This allows for repeated or continuous administration of medications. You might be given a test dose to make sure the epidural is positioned correctly. It takes about one to 15 minutes for the medication to take effect, depending on the type of anesthetic used. Your health care provider will discuss with you the best time to request an epidural during labor. You might not be able to have an epidural if you have had major surgery in your lower back, have low blood-clotting factors, have an infection in your lower back or are on certain blood thinners.
Pros
An epidural alleviates most pain in the lower body without significantly slowing labor. You'll remain awake and alert but you will still feel pressure and some stretching during delivery. A combined spinal-epidural block, which takes effect quicker than does an epidural and has lower doses of anesthetic medications, might leave you with more muscle strength.
Cons
You could experience an inadequate or failed epidural. An epidural might decrease your blood pressure, which might slow the baby's heart rate. You could develop a fever or itchiness or experience postpartum soreness in your back. Rarely, you might develop a bad headache. Even if you have a combined spinal-epidural block, sometimes called a walking epidural, you will likely not be able to walk during labor.
