Brief summary (from the registry)
For patients scheduled to undergo upper limb sympathetic nerve block due to chronic neuropathic pain in the upper limb lasting more than 3 months, the ultrasound-guided stellate ganglion block group (S group) and the fluoroscopy-guided thoracic sympathetic nerve block group (T) Patients are randomly assigned 1:1 to one of the groups, and the procedure is performed. To evaluate the effectiveness of sympathetic nerve blockade, temperature changes in both palms are measured twice, 20 minutes before and 20 minutes after the procedure, using an infrared thermographer. Other variables related to the procedure are surveyed by outpatient visit or telephone before the procedure, after the procedure, before returning home, and 1 week and 1 month after the procedure.
