nerve transmission in a region of the body - in this case a fine catheter (tube) is passes into the epidural space around the spinal cord and the local anaesthetic is injected here.
Usually the chemical agent include a long acting local anaesthetic, such as mepivacaine, and maybe also a painkiller such as fentanyl citrate, so that the effect lasts for some hours. By positioning the patient, the anaesthesia can be controlled to only block the sensation in the lower limbs.
The dose can also be controlled so that after surgery some movement is possible in the limbs although pain remains blocked.
