I used a morphine pump twice after major spine surgery. Both times it was a complete failure. Later, I tried the Fentanyl Transdermal system and achieved an 80% reduction in chronic pain.
We're all different. That which helps one of us may do nothing for another one. That's why it's so important to try each and every long and short-acting pain drug before deciding upon a course of action. More often than not, for chronic pain, the answer lies in a combination of a long-acting pain medication (Kadian, Oxy-Contin, Fentanyl Transdermal, etc.) PLUS a short-acting drug (Hydrocodone, Oxycodone, etc.) for breakthrough pain. Often times, BOTH must be used together to accomplish the desired result.
To add efficacy, anyone with chronic pain should consider an anti-depressant (Cymbalta, etc.) because anti-depressants will inhibit the reuptake of Seratonin, one of the body's natural pain-fighting chemicals.
If the patient has referent pain, add an anti-convulsant, such as Lyrica or Neurontin.
If the patient has osteoarthritis or some other auto-immune/inflammatory condition, add an anti-inflammatory (Celebrex, etc.).
After 40 years of experimentation with my trusted family physician, we have isolated the best of each of the above-mentioned medications for my unique body chemistry. Remove any of these medications and my pain comes crashing back. But used together, like a fine symphony orchestra, my pain is kept at bay and my pain is tolerable. My point here is to say that chronic severe pain often requires the concurrent administration of long and short-acting opioids, plus anti-depressants, plus anti-inflammatories, etc. It is this "cocktail" of drugs that allows us to survive and thrive. Yet, so many physicians today are reluctant to prescribe combinations of medications. I can tell you that these combinations are the only way that many of us continue to survive.
The secret to this success is to have a physician willing to allow you to try dozens of different medications, in combination, until the BEST combination is realized. This can take many months or even years to accomplish. But, when it comes to your health, it's worth it.
If all of this fails, then it might be appropriate to seek the intrathecal infusion pump or the spinal cord stimulator. But beware that the long-term success rates for both mechanisms are in the range of 60% (see
http://www.painphysicianjournal.com/2009/july/2009;12;699-802.pdf ). And remember that surgery is required to implant and to remove these barely-successful mechanisms. And all surgery entails morbidity. Having a machine implanted in your body with a 60% success rate seems like a very last-resort option to me. On the other hand, those who cannot benefit from oral and Transdermal pain medications might see no other alternative.
