Spinal anesthesia : A needle will be passed into space around the spine. The medicine will be sent into the fluid that surrounds the spinal cord. It will be given in 1 injection.
Epidural anesthesia : A needle will be passed into space around the spine. The medicine will be sent into the fluid that surrounds the spinal cord. A tiny, flexible tube may be left in place just outside of the fluid sac. This will allow more doses to be given if it is needed.
A bandage will be placed over the area when the process is done.
