In this case series of 285 patients, stellate ganglion block was associated with a significant reduction in anxiety symptoms, with mean GAD-7 scores dropping by more than half within one week and remaining improved at one month.

A comprehensive review examining the role of Stellate Ganglion Block (SGB) as an adjunctive treatment for PTSD, long COVID, chronic fatigue syndrome, menopause symptoms, and other autonomic disorders.

Review of the clinical evidence regarding IV ketamine treatment for major depressive disorder (MDD)

This foundational study evaluated cervical sympathetic block (Stellate Ganglion Block/SGB) in multiple PTSD patient cohorts and found meaningful symptom improvement across a wide range of individuals. It remains an important piece of the growing body of evidence supporting nervous system-focused treatment for PTSD.

Does everyone respond to a right-sided Stellate Ganglion Block (SGB)? This study suggests not. Researchers found that many patients who did not improve after a right-sided SGB experienced significant symptom relief following a left-sided procedure, reinforcing the importance of an individualized treatment approach.

This landmark randomized controlled trial (RCT) demonstrated that Stellate Ganglion Block (SGB) produced significantly greater improvements in PTSD symptoms than a sham procedure. The study remains one of the strongest pieces of evidence supporting nervous system-focused treatment for PTSD.
