This study examined possible psychological differences between Reflex Sympathetic Dystrophy (RSD) and non-RSD chronic pain patients. Unlike the few previous studies in this area, this study controlled statistically for age and pain duration differences across diagnostic groups, and included a non-RSD limb pain control group. Subjects were a consecutive(More)
OBJECTIVES To examine the validity of several thermogram-derived indices of autonomic functioning in the diagnosis of reflex sympathetic dystrophy (RSD). DESIGN A series of chronic pain patients were classified diagnostically based on thermogram results using discriminant function analysis, and validity measures (e.g., sensitivity, specificity) were used(More)

OBJECTIVE To compare pain relief in metastatic pancreatic cancer patients between neurolytic celiac plexus block (NCPB) and epidural 5% butamben suspension (EBS), a material-based delivery system of a local anesthetic that produces a long-lasting differential nerve block. DESIGN Open-label patient-selected parallel groups. SETTING Urban tertiary care(More)
UNLABELLED Butamben, a lipophilic local anesthetic of the ester class, produces a differential nerve block of long duration. Epidural and peripheral nerve blocks with butamben, formulated as a 5%--10% suspension, result in prolonged analgesia without significant motor blockade. We evaluated the effect of butamben sciatic nerve block on antinociception using(More)
