Seattle Stellate Ganglion BlockDr. Forest Dobbs is performing the stellate ganglion block (SGB) procedure for the treatment of post-traumatic stress disorder and other conditions related to trauma, chronic pain and chronic stress.  This a 15 min procedure that involves injection under ultrasound guidance of a long-acting local anesthetic at the base of the neck.  Benefits are seen in as little as 30 minutes.

How does it work?

The anesthetic bathes the stellate ganglion in the cervical sympathetic chain, the main bundle of nerves that controls the “fight or flight” response (the sympathetic nervous system), which is overactivated in PTSD and chronic pain.  By temporarily blocking signaling in the cervical sympathetic chain, it is believed that amygdala and other brain centers involved in the fight or flight response are allowed to completely reset, resulting in long-term relief of the associated anxiety symptoms.  Patients report minimal to no discomfort with the procedure.  It is generally repeated twice over a two-week period and can be repeated as needed.  Outcomes are tracked with the PCL-5 checklist instrument which can be viewed here.

Beyond PTSD and pain

SGB can potentially treat these additional conditions based on emerging evidence listed below:

  • Long COVID symptoms (include fatigue, brain fog, anosmia, dysgeusia, orthostatic intolerance, cough)
  • Dysautonomia
  • POTS (Postural orthostatic tachycardia syndrome)
  • Chronic fatigue syndrome (ME/CFS)
  • Dysgeusia (perception of taste is altered; everything seems sweet, sour, bitter, or metallic)
  • Ageusia (loss of taste)
  • Parosmia (Inability to properly identify an odor’s “natural” smell)
  • Anosmia (loss of smell)
  • Tinnitus
  • Sudden Deafness
  • Migraine

Stellate Ganglion Block Pricing*


Covered Service Fee Non-Covered Service Fee Late Cancellation Fee
(Within 48 hours of Visit)
SGB Injection under Ultrasound Guidance $240 $655 $150

*Stellate Ganglion Block for conditions other than select pain syndrome is currently considered an experimental procedure by major insurance companies. AIMS can directly bill contracted insurance companies for the management and coordination of care before and after procedure and for nurse safety check visit ($35 if direct pay).  If SGB includes ketamine prescribed and administered by appropriately licensed clinicians, an additional $45 charge will be added.

Effect of Stellate Ganglion Block Treatment on Posttraumatic Stress Disorder Symptoms A Randomized Clinical Trial

JAMA Psychiatry | Original Investigation

November 2019

Kristine L. Rae Olmsted, MSPH; Michael Bartoszek, MD; Sean Mulvaney, MD; et al.

CONCLUSIONS AND RELEVANCE In this trial of active-duty service members with PTSD symptoms (at a clinical threshold and subthreshold), 2 SGB treatments 2 weeks apart were effective in reducing CAPS-5 total symptom severity scores over 8 weeks. The mild- moderate baseline level of PTSD symptom severity and short follow-up time limit the generalizability of these findings, but the study suggests that SGB merits further trials as a PTSD treatment adjunct.
