Etomidate vs Ketamine

it provides a temporary relief of breakthrough pain for patient,

I have had over 10- 4 hour ketamine infusions for rsd/crps pain. Ketamine is the only drug that has helped decrease the pain, swelling and burning associated with the rsd. I had very little side effects and the results last about 4 to 6 months. Most insurance plans will not pay for the procedure and it is expensive, but worth every cent.
