I happened to watch the 60 minute segment on Stellate Ganglion Block for PTSD. Stellate Ganglion Blocks have been around for a long time, and I performed them from time to time as an Anesthesiologist. The theory behind this for PTSD is that it might affect sympathetic activity (fight/flight) to quell the attacks of panic and despair in PTSD patients. It’s safe enough. I would like to point out, however, they have yet to do controlled studies!! So this could not pan out and turn out to be placebo. But I will keep watching this project. Pinpointing autonomic activity is ever more popular. I’ve been doing it for years in conjunction with acupuncture.
