Epidural anesthesia is the injection of a numbing medication into
the space around the spinal nerves in the lower back. The medication numbs the
body below the point of injection, but the person remains awake and may have
some control of the numbed area.
The skin where the needle will be inserted is first numbed with a
local anesthetic. A guide needle is inserted and then removed, and a catheter
remains in place. The anesthetic is then injected through the catheter.
Medication that makes the person sleepy also may be used by injecting it into a
vein, depending on the procedure being performed.
Epidural anesthesia may be used for certain types of surgery on the
lower body or to control pain during childbirth. When a woman has an epidural
anesthetic during childbirth, she will feel little or no pain from her
contractions.
