The epidural space
is a space very close to the spinal chord which is located
over the dura mater. An injection into this area is
usually called the epidural, and the injection causes
the patient to lose sensation in the pelvic region.
Epidurals are used in prostate cancer treatments such
as temporary brachytherapy
treatment or other treatments where patients do not
wish to undergo general anaesthesia. Prostate cancer
patients who opt for epidurals are often given sedatives
in addition to decrease anxiety and involuntary movements
that could complicate the prostate cancer treatment.
