What is the Stellate Ganglion Block (SGB)?

The Stellate Ganglion Block (SGB) treatment is a widely used procedure shown to provide relief from symptoms like continual sleep disturbance, surges of anxiety and irritability, hypervigilance, difficulties concentrating and jumpiness. These symptoms are commonly observed in those who are exposed to extreme stress, or traumatic events. Stella’s SGB procedure, the Dual Sympathetic Reset, involves an injection, by a trained Stella doctor, into a group of nerves in the neck – which is typically completed in less than 20 minutes.

The Stellate Ganglion Block (SGB)

SGB is an injection of a local anesthetic into the stellate ganglion, a nerve bundle in the neck connected to the fight or flight system, to help people feel calm again in their own bodies.

We adapted SGB for PTSD

In 2006, Dr. Eugene Lipov, our Chief Medical Officer, pioneered the procedure for use in alleviating PTSD symptoms by reducing amygdala (“fear center”) overactivity. The procedure ‘unsticks’ the brain from the continuous state of fight or flight.

SGB Treats the Physical Injury of Trauma

Exposure to high stress or traumatic events often results in debilitating symptoms that can originate from the sympathetic nervous system’s fight or flight response. When individuals suffer from trauma-related symptoms, the fight or flight response can stay in “high gear” long after the trauma.

The SGB procedure interacts with the sympathetic nervous system to help restore normal biological function and can efficiently address many of the most severe symptoms associated with trauma – usually within one or two clinical visits.

Using image guided, a highly trained Stella doctor injects a local anesthetic into the Stellate Ganglion – a bundle of nerves found near the base of the neck. The entire process is completed in under 20 minutes. The treatment can help support the brain’s natural fight or flight response and can lead to a restored sense of safety and calm for many patients.

SGB has been shown to have dramatic positive effects in many patients and can also help accelerate the positive impact of other therapies.
