I've had 7 intravenous lidocaine infusions since July 2009. They have been maybe 20-30% effective, for 2 weeks or so, at a time, in controlling my pain. What they helped with most was the deep burning bone pain in my leg, a little over a year after I was diagnosed. Before I started the infusions I could barely sleep because of the pain. My infusions built upon each other, such that I felt better and better after each one, and generally they were scheduled 3-4 weeks apart when my doctor's schedule permitted.
I did have a continuous anesthesia drip left in my shoulder for 4 days after my 2nd rotator cuff repair, I don't know what was in it. I was pain free for the first time in months after the surgery - it was awesome! My RSD was diagnosed 6 weeks later. I haven't had any complications from the drip.
I know I have read at least one article on lidocaine infusions by Schwartzman at RSDSA. org. The amount of lidocaine that most PM centers are authorized to provide in one infusion is 300 mg (I almost certain). Dr. S has done continuous infusions for 5 or 7 days at much higher amounts with fairly good results.

I'm now a little leary of lidocaine because of an issue with a friend. She tore her rotator cuff and had surgery to fix it. After the surgery they used a lidocaine infusion device locally to help decrease the pain. It has been very effective in drastically cutting down the amount of systemic narcotics that they give those patients after surgery. Unfortunately, they are now discovering that many of these patients developed further shoulder issues. It seems the lidocaine destroys the bone and other tissues. They are guessing because of the continuous infusion.......it's not like a one time shot like we all get with the steroids in a trigger point injection. My friend has had 9 shoulder surgeries now and multiple procedures to drain infections and remove scar tissue to try to fix the problem. Her ortho wants her to have a shoulder replacement done, but that specialist can not do it because there is not enough healthy bone left for them to connect the hardware to.
I've always been kind of a lidocaine 'fan' When get trigger point injections I don't get much long term relief but I love the next 3 or 4 hours when my pain is G O N E ! I've been a nurse for over 20 years and I had never heard about an allergy to lidocaine or any issues with it until my friend's shoulder issues came to light.
While I happy new research is being done, the news that it is with a lidocaine infusion worries me now. Please do all the research that you can and read all of the fine print on those consent forms !
