The
diagnosis and management of
Complex Regional Pain Syndrome, formerly known as
Reflex Sympathetic Dystrophy
has always been a
controversial issue. However, the Social Security Administrations ruling in the Federal Register
on October 20, 2003 provides helpful diagnostic
guidelines. There is, however, still no consensus on how to appropriately treat CRPS.CRPS is diagnosed by documenting a history of injury in any
part of the body, especially the limbs, followed by complaints of severe pain, skin
sensitivity, swelling and reddish purple discoloration, sweating, hair loss or growth,
atrophy, and warmth in the acute setting but cold in the chronic setting. Contrary to
popular belief CRPS can spread to any part of the body, including internal organs and can
also affect hormone regulation.
CRPS is classified into Type I and Type II. The clinical features are basically
the same in both categories. The only difference is that no specific nerve injury can be
identified in Type I, whereas in Type II, nerve injury can be documented. In addition to
obtaining a good history and physical examination, some useful diagnostic tools include
thermography, bone scan, quantitative sensory testing and sweat output measurement.
Although there is no known cure for this
disease, it can be controlled if treated within three months of actual onset, not
diagnosis. We have more than seven years of experience in the diagnosis and management of
CRPS
using a multi-disciplinary, non surgical approach with
the proper combination of medications, nerve blocks, massage, and physical and
occupational therapy. Our protocol has been most effective in reducing pain and suffering,
thereby improving quality of life and activities of daily living.
We do not recommend surgery for the
management of CRPS unless there is a critical or life threatening problem.
The pain of CRPS can mimic symptoms of carpal tunnel syndrome, ulnar
neuropathy and disk herniation, and it is wrong to operate in such cases.
Ganglion
blocks may be helpful if given within three months of disease
onset, but not in chronic cases. In our experience, no patient referred to us has ever
benefited from the use of a spinal cord stimulator.
Conventional opiates such as Oxycontin,
Dilaudid, Lorcet, Lortab, MS Contin are excellent analgesics in the acute setting but have
limited value in chronic cases due to their long term side effects. Antagonist opiate
analgesics such as Buprenex or Nubain are better alternatives because of their lesser
addicting properties. We have found that antidepressants such as Trazodone and Effexor XR,
muscle relaxants like Klonopin and Zanaflex, anticonvulsants like Trileptal and Neurontin,
and anti-inflammatories like Mobic, when used in the appropriate circumstances,
are helpful in reducing the symptoms and signs of
CRPS.
