Sympathetic Blocks Provided Sustained Pain Relief in a Patient with Refractory Painful Diabetic Neuropathy
Figure 2
Sympathetic block-induced changes in temperature and NRS pain scores. (a) The peak temperatures, monitored at the plantar surface of the toes with an electronics device, increased significantly in both sides after bilateral lumbar sympathetic blocks (post) compared to the baseline values taken before the blocks (pre). (b) The NRS pain scores, evaluated in the preprocedure room before the blocks (pre) and in the recovery room after the block (post), decreased significantly after each lumbar sympathetic block.
