Transition from Deep Regional Blocks toward Deep Nerve Hydrodissection in the Upper Body and Torso: Method Description and Results from a Retrospective Chart Review of the Analgesic Effect of 5% Dextrose Water as the Primary Hydrodissection Injectate to Enhance Safety

Figure 23

Graph showing the time course of changes in pain caused by hydrodissection with 5% dextrose water for chronic neuropathic pain. Time course of changes in 0–10 NPRS for all 26 cases (25 patients; one underwent bilateral treatment) grouped according to the number of treatment sessions. The last dot on each line represents the final pain score obtained by telephonic interview at 2 months after the last treatment session. The other dots at the beginning and along each line represent the mean pain scores for that group at each point during treatment.
