Stellate Ganglion Block Relieves Long COVID-19 Symptoms in 86% of Patients: A Retrospective Cohort Study, 2023, Pearson et al

Abstract

Post-COVID-19 condition, also known as long COVID-19 syndrome and post-acute sequelae of SARS-CoV-2, encompasses an array of symptoms that persist well beyond the initial phase of the viral infection. These symptoms can range in intensity, from mild and manageable to severe and incapacitating. Due to the evolving nature of the SARS-CoV-2 pandemic, treatment protocols for the illness are in a constant state of evolution. The early stage of long COVID-19 syndrome contributes to a dearth of treatment protocols based on empirical evidence, while the absence of a conclusive pathophysiological understanding further complicates the development of such protocols.

Current treatment regimens include homeopathic medicine, specialist system-focused treatments, infusion therapies, hyperbaric oxygenation, antivirals, and polypharmacy. The physiological, psychological, and societal impact of long COVID-19 cannot be approached casually and must govern the intensity with which the healthcare community approaches the treatment of long COVID-19 syndrome.

In this 41-patient cohort study from a chronic pain management practice, the use of either unilateral or bilateral stellate ganglion block (SGB) was explored to manage symptoms associated with long COVID-19 syndrome. Results indicated that a substantial proportion of patients (86%) experienced a reduction of their symptoms following SGB treatment.

Basically they retrospectively asked people treated with the therapy at their clinic about their symptoms and the results are based on their replies. No control group or anything. I just took a quick glance but I'm not sure we even know how many didn't reply, probably we don't. There may be even more to unpack here. Also, they say they have no conflict of interest interestingly, although these people were treated at their clinic?
