Condition: Long COVID · Sponsor: Centre intégré universitaire de santé et de services sociaux de la Mauricie-et-du-Centre-du-Québec
This single-center, randomized, controlled, single-blind clinical trial evaluates whether a stellate ganglion block (SGB) using bupivacaine can improve persistent symptoms in adults with long COVID. Participants are assigned in a 1:1 ratio to receive either an ultrasound-guided right-sided SGB or a placebo saline injection delivered to the sternocleidomastoid muscle. After the intervention, participants are followed for 26 weeks with scheduled evaluations that include symptom questionnaires and functional tests. The study assesses changes in functional status, fatigue, cognitive complaints, quality of life, dyspnea, lower-limb endurance, and orthostatic tolerance over time. Safety is monitored throughout all follow-up visits. Approximately 40 participants meeting predefined eligibility criteria will be enrolled. This trial seeks to determine whether a single stellate ganglion block has an effect on persistent long-COVID symptoms compared with placebo.The results will help determine the therapeutic value of SGB in the management of long COVID and inform future research and clinical practice.
