Why an epidural is likely to exert effects on nerves with slower and prolonged action than a spinal tap?
Essentially, when a spinal tap is given, a needle is inserted into the spinal canal in the lumbar area, medicine (or an anesthetic) is inserted directly into the cerebrospinal fluid (CSF). Numbness is usually immediate. However, in an epidural, a hollow needle and a catheder are inserted into space between the spinal column and the outer membrane of the spinal cord (EPIDURAL space). Hence the name "epidural".
