The evidence regarding the clinical effectiveness of stellate ganglion block for the treatment of post-traumatic stress disorder was mixed. A randomized controlled trial included in a systematic review did not detect significant differences in post-traumatic stress disorder symptoms in the stellate ganglion block versus sham groups, while another randomized controlled trial did detect significantly greater improvements in symptoms between these groups. Furthermore, the second randomized controlled trial detected significantly greater improvements in depression, anxiety, and distress, but not in pain and mental and physical functioning for participants receiving stellate ganglion block compared to sham.
Authors of the randomized controlled trial included in the systematic review did not detect significant differences in rates of adverse events between groups. Of the 6 adverse events reported in the second randomized controlled trial, 3 were deemed related to stellate ganglion block treatment (injection site pain, self-resolving bradycardia, and temporary laryngeal irritation); the statistical analysis was not reported.
Authors of 1 evidence-based guideline were unable to provide recommendations for or against the use of stellate ganglion block for the treatment of post-traumatic stress disorder because of insufficient evidence.
No relevant literature or guidelines regarding the clinical effectiveness or use of stellate ganglion block for the treatment of depression or anxiety were identified.
