Abstract

The term "sympathetically maintained pain" (SMP) describes a symptom that might accompany a variety of diseases (CRPS, (post-) herpetic and post-injury neuralgia), which might transform into sympathetically independent pain (SIP) after some time. Patients with SMP present a bunch of disorders of the autonomic and sensory system, but the only reliable way to diagnose a pain as SMP is a positive response to an intervention at the sympathetic nervous system. Three ways of influencing the sympathetic system are commonly used: (a) local anesthetic sympathetic blockade (SB), (b) intravenous regional sympathectomy (IVRS) and (c) ganglionic local opioid application (GLOA). A review of current literature shows that SB has certain advantages in diagnostic sensitivity, whereas GLOA might be slightly superior in therapy of some diseases with longstanding pain history. Obviously, the therapeutic benefit of all interventions is complete independent of the accompanying autonomic disorder and of a blockade of efferent fibers. A new heuristic model of the SMP mechanism is presented, including both experimental and clinical data. For reducing the risks of false positive or negative diagnosis of SMP and SIP, a diagnostic algorithm is proposed. This includes optimizing the technique, changes of interventional measures, and adequate monitoring both of analgesia and as well of the extend of efferent sympathetic blockade (e.g. measurement of sympathetic reflexes). The treatment recommendations in patients with SMP vary in dependence of the kind of disease. In SMP, invasive measures play an important, but only limited role within the comprehensive treatment concept. As an example a three-stage, symptom-adapted treatment algorithm is demonstrated for CRPS, including also drug therapy, psychologic and physiotherapeutic approaches.
