Study Summary
This single-center study aims to evaluate both immediate and long-term outcomes of stellate ganglion block (SGB) in a cohort of rigorously phenotyped patients with Postural Tachycardia Syndrome (POTS). By assessing the effects of SGB, this study seeks to determine its viability as an intervention for symptom control in POTS.
Primary Outcome
The change in Composite Autonomic Symptom Score 31 (COMPASS-31) from baseline to first follow-up visit. The COMPASS-31 scale measures autonomic dysfunctions through 31 patient-reported questions. A higher score indicates worse autonomic dysfunction.
Interventions
- DRUG Normal saline
- DRUG Ropivacaine
- PROCEDURE Stellate ganglion block
- PROCEDURE Sham injection of saline
