Hi.

These two articles, both courtesy the RSDSA http://www.rsds.org/index2.html may be useful.

The first article is written for the patient's perspective, "Overview of Ketamine Infusion Therapy," by Philip Getson, DO at http://www.rsds.org/3/treatment/ketamine.html

And the second, while more technical, is from one of the leading RSD practitioners in the U.S., Robert J. Schwartman, M.D., and the first to show in a double-blind controlled trial that at least the Drexel protocol for "low dose" ketamine appeared to be of substantial benefit in a small controlled trial, surprisingly suggesting that the benefit extended even to a patient population that included a lot of people who had had the disease for a year or more. "Outpatient intravenous ketamine for the treatment of complex regional pain syndrome: A double-blind placebo controlled study," Schwartzman RJ, Alexander GM, Grothusen JR et al, Pain 2009 Dec 15;147(1-3):107-15.

Hope these help.
