In Nov 2005 I had a e 3 level fusion in my lumbar back. I have had RSD in my feet since 2003, exacerbated in the left by having 2 neuroma's removed cause the podiatrist said that they were causing the pain. I have 2 in the right foot but they are still in there & my left is still worse than the right. Anyway during my back surgery they bathed my spine with Ketamine & I had NO spread to the surgical site. The spine surgeon, anesthesiologist & my PM Doctor talked before my surgery & several times during my surgery. It was a 4 hr surgery. It did take me alot longer to wake from this surgery than from any previous surgery but no other adverse effects from the Ketamine either. No hallucinations etc.

Hope this is helpful.
