PTSD and Stellate Ganglion Block: 60 minute segment

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.
