A review of the use of stellate ganglion block in the treatment of PTSD.

Current treatments for PTSD are often not effective or acceptable to the patient. There are a number of emerging new treatments. One promising new one is stellate ganglion block, an anesthetic treatment for pain which relieves symptoms of severe and chronic PTSD in some patients. The focus of this chapter is to summarize clinical evidence available for the effectiveness of cervical sympathetic ganglion injection called stellate ganglion block (SGB), as well as demonstrate possible clinical applications of its use. Cervical sympathetic blockade involves injecting a local anesthetic next to a group of nerves (ganglion) in the neck. The technique has been used clinically since 1925 with very few side effects. Finally, the neurobiology of SGB is discussed. Challenges to the use of SGB include the lack of randomized clinical trials and practitioners familiar with the use of SGB for PTSD.
