Dear finz -
One of the key techniques in blocking the spread of RSD in sugery is the use of something called "continuous regional anesthesia" during the procedure. The idea is that while a genereal anesthetic knocks you out, only the application of a local to the affected area prevents the flow of pain processing signals to the dorsal horn of the spinal cord, and ultilmately the brain, which in turn may trigger greater sensitization and the spread of RSD.
A good group of articles in pdf formats on the subject appears under the heading of "CRPS and Surgery
" on the RSDSA Medical Articles Archive page at http://www.rsds.org/2/library/articl...ve/index.html:
