Optimizing clinical outcomes with stellate ganglion block and trauma-informed care: A review article.

Abstract

For decades, thousands of active-duty service members have sought treatment for trauma exposure. Stellate ganglion block (SGB) is a fast-acting nerve block documented in medical literature for nearly a century that has shown promise as a potentially life-altering treatment for post-traumatic stress (PTS). This review aims to answer the practical questions of those who support individuals suffering from trauma: (1) SGB's safety profile (2) efficacy data (3) potential advantages and limitations, (4) a cross-cultural application example, (5) and the use of SGB in combination with talk therapy to optimize clinical outcomes. The current body of literature, to include several large case series, meta-analyses, and a sufficiently powered randomized controlled trial, were reviewed, and presented to describe the history of SGB for emotional trauma symptoms and address the objectives of this review. Critical consideration is given to the safety and efficacy data on SGB and the evolution in safety-related technologies. Advantages such as decreased barriers to care, rapid onset, and decreased dropout and limitations such as treatment non-response, potential adverse effects, and misconceptions about the treatment are then described. Finally, the cross-cultural application of SGB is explored based on the deployment of SGB in Israel. Stellate Ganglion Block is associated with level 1B evidence and a reassuring safety profile. Evolving the model of care through the combined use of effective biological treatments like SGB with trauma informed talk therapy offers a hopeful path forward for supporting those who suffer from post-traumatic stress.
