Key result
Stellate ganglion block resulted in immediate improvement of long COVID symptoms, including a 50% reduction in fatigue and a 40% reduction in shortness of breath.
Why the study?
Many prolonged sequelae of long COVID are thought to be mediated by autonomic nervous system dysregulation, prompting investigation of stellate ganglion block for symptom management.

Does stellate ganglion block improve symptoms in a patient with long COVID?
Stellate ganglion block may be an effective treatment modality for alleviating sympathetically-driven long COVID symptoms such as fatigue, shortness of breath, and gastrointestinal disturbances.
May support SGB for long COVID autonomic symptoms; hypothesis-generating and requires randomized trials before practice change.
Stellate ganglion block (SGB) is gaining increasing acceptance as a treatment modality for various medical conditions. It works by blocking neuronal transmissions which in turn alleviates sympathetically-driven disease processes. Many of the prolonged sequelae of long COVID are thought to be mediated by dysregulation of the autonomic nervous system, and SGB is being investigated as a potential option for symptomatic management of long COVID. This case report demonstrates the efficacy of SGB in a previously healthy patient for the management of long COVID symptoms including fatigue, post-exertional malaise, shortness of breath, and gastrointestinal symptoms. .

Khan et al. (2022) conducted a case report in Long COVID (n=1). Stellate Ganglion Block was evaluated on Symptom severity (1-10 scale). Stellate ganglion block resulted in immediate improvement of long COVID symptoms, including a 50% reduction in fatigue and a 40% reduction in shortness of breath.
