Somatic or sympathetic block for reflex sympathetic dystrophy. Which is indicated?

Abstract

Patients with reflex sympathetic dystrophy (complex regional pain syndromes) are often referred to pain medicine physicians for assistance in providing pain control during rehabilitation of their painful upper extremity. When deciding which pain control technique to use in an individual patient, physicians must consider both somatic and sympathetic blocks. Each of these nerve blocks has advantages and disadvantages that may be tailored to an individual patient's pain state and rehabilitation program to optimize recovery.
