Stellate Ganglion Block (SGB)—a medical procedure that effectively treats symptoms associated with posttraumatic stress disorder (PTSD)—is an injection of local anesthetic in the neck to temporarily block the cervical sympathetic chain which controls the body’s fight-or-flight response.
SGB has been safely used for over 80 years for many other reasons but was discovered ten years ago to provide relief of PTSD symptoms as well. Since that time, along with a handful of other physicians, I have pioneered the use of SGB for treating posttraumatic stress within the US Army. Due to its safety, success rate, and rapid onset of relief, SGB has gained wide acceptance in several locations at US military hospitals where it has been available.
