Sympathetic nerve blocks: In search of a role*1

Abstract: Changes in the understanding of CRPS disorders and the role of the sympathetic nervous system in neuropathic pain has changed both the diagnostic and management strategies for these pain states. The sensitivity and specificity of response to sympathetic blocks in establishing their value at diagnostic aids will not be fully established without further clinical study. Further use of intravenous regional blocks or diagnostic intravenous infusions remains questionable. Preventive and therapeutic use of sympatheti… Show more

“…Usually, blocks are performed by (repeatedly) administering a single dose (single-shot) of local anaesthetic around the sympathetic chain. The duration of action of such blocks varies from 1 to 12 h depending on the active agent, dose and concentration used [3]. We believe that this duration of blockade may be too short and may explain failures of the technique in some patients.…”

“…Patients who benefit from continuous blockade of their thoracic sympathetic chain by local anaesthetic most probably will respond to neuroablation [14]. There are numerous feasible methods of disrupting the sympathetic nervous system including surgical sympathectomy, percutaneous chemical neurolysis and radio frequency thermoablation [3]. We performed chemical neurolysis using ethanol, as the use of phenol for neurolytic procedures in non-malignancy pain syndromes is not approved by local authorities in Germany.…”
