General Anesthesia
With general anesthesia, you are unconscious and have no awareness of the surgical procedure or other sensations.
Epidural Anesthesia
An
anesthesiologist injects medicine and usually puts a catheter in a
space near the spinal cord (above it and separated by a thick membrane)
to give you numbing and narcotic medication to stop pain signals from
the surgery site from being perceived by your brain. Epidural analgesia
is most often used in obstetrics and orthopaedic and thoracic surgery.
Nerve Block Anesthesia
An
anesthesiologist injects medication near a cluster of nerves to numb
only the area of your body that requires surgery. You may remain awake
or you may be given a sedative so that you are not aware of the
operation being performed. Sometimes you can go home with the numbing
medication being given through a special pump to keep your pain under
control.
Spinal Anesthesia
A small amount of numbing medicine
is inserted into the fluid around the spinal cord (well below
where the spinal cord ends) to numb the lower half of your body to
allow an operation to be performed there without any sensation. Spinal
anesthesia usually lasts between two and six hours.
