The Success of Lumbar Sympathetic Ganglion Block Using Lower Extremity Perfusion Index: A Prospective Observational Study
In Brief
A clinical study evaluating Lumbar Sympathetic Ganglion Block for Chronic Pain and 3 related conditions. Completed, enrolled 40 participants across 1 site.
Detailed Summary
The patient, who is experiencing chronic pain in the lower extremities persisting for more than three months, is scheduled to undergo lumbar sympathetic ganglion block. To evaluate the technical success of the sympathetic blockade, temperature and perfusion index (PI) will be measured at one-minute intervals over a 20-minute period before and after the procedure on the treated side and the opposite side foot. Additionally, other variables related to the procedure will be assessed before the procedure, after the procedure, before discharge, and during follow-up outpatient visits or phone surveys at 1 week and 1 month after the procedure.

Timeline
Interventions
A needle will be inserted at the L3 on the side experiencing pain, either right or left, under fluoroscopy guidance. Once the needle is positioned in front of the desired vertebral body, its location is confirmed using a contrast medium. If the position is well visualized in lateral and anteroposterior (AP) views, 7 mL of 0.5% ropivacaine will be injected.
