Regional anesthesia technique used in childbirth and major surgeries that provides continuous pain control through a thin catheter placed in the lower back.
Indication
- Labor analgesia (painless childbirth)
- Cesarean delivery (when prolonged analgesia is required)
- Intra- and postoperative pain control in major abdominal, thoracic, and orthopedic surgery
- Vascular surgery and lower extremity operations
- Chronic pain treatment (in selected indications)
- Pain control for postoperative respiratory support in patients with lung disease
Preparation
- Anesthesia evaluation, blood tests, and coagulation tests
- Adjustment of blood thinners with physician approval
- Reporting prior back surgeries, spinal problems, and neurological history
- An IV line is placed and fluid administration is started
- For labor analgesia, the procedure is planned at an appropriate stage of labor
How it's performed
- The patient is placed in a sitting or side-lying position with the back curved forward
- The skin is cleaned with antiseptic and numbed with local anesthesia
- A special epidural needle is used to find the epidural space (outside the spinal cord membrane)
- A thin catheter is placed through the needle and the needle is removed; the catheter is secured to the skin
- Anesthetic/analgesic medication is administered continuously or intermittently through the catheter
- Vital signs and sensory-motor block are continuously monitored
Post-procedure
- Pain control can be provided through the catheter for hours to days as needed
- During labor, the mother can move; full pain relief is usually achieved in 10-20 minutes
- Brief tenderness at the insertion site may occur after the catheter is removed
- Blood pressure and urine output are monitored in the first hours
- Severe headache, back pain, or weakness in the legs should be reported to a physician
Risks
- Transient hypotension
- Post-dural puncture headache (PDPH) — may develop if the membrane is accidentally punctured; treated with bed rest, fluids, and an epidural blood patch if needed
- Inadequate or one-sided block (catheter may need to be repositioned)
- Difficulty urinating, nausea, and itching (medication-related)
- Very rare: permanent nerve damage, epidural hematoma, or infection
FAQ
What is the difference between epidural and spinal anesthesia?
In spinal anesthesia, the medication is injected directly into the cerebrospinal fluid; the effect is rapid and short-lasting. In epidural anesthesia, the medication is injected into the space outside the membrane; the effect begins gradually but can be sustained for hours via a catheter.
Does epidural anesthesia harm the mother or baby during childbirth?
With modern protocols, epidural anesthesia is considered safe for both mother and baby. There is minimal effect on the course of labor, and medication exposure to the baby is low.
Will I have permanent back pain after an epidural?
Brief tenderness may last a few days. A direct link between the epidural and permanent back pain has not been demonstrated; most chronic back pain is due to other underlying causes.
What is done if I get a headache?
Most cases resolve within 5-7 days with bed rest, plenty of fluids, caffeine, and simple pain relievers. If it persists, rapid recovery is achieved with an epidural blood patch.
