Spinal cord stimulation revisited.

The proportion of patients with intractable pain successfully managed with spinal cord stimulation (SCS) remains disputed. We analyze 27 consecutive patients with intractable pain treated with SCS using identical hardware (Itrel II System; Medtronic Neurological, Inc Minneapolis, MN, USA) by a single satisfactory diagnosis 1992 through 1995. A rigid selection protocol was used: 1. A satisfactory diagnosis of the pathologic process resulting in pain was made. 2. A corrective surgical procedure was judged not feasible by surgeons experienced in the particular pathology, e.g., vascular peripheral nerve, spine. 3. Lack of satisfactory response to noninterventional pain management modalities by an interdisciplinary pain clinic. 4. Independent psychological evaluation, including a structured interview was performed by a psychologist specialized in chronic pain management. In the last eight cases, a battery of self-report tests designed to assess psychosocial and behavioral consequences of the chronic pain problem were administered as well. All cases were of nonmalignant pain, except for one patient. Thirteen cases were diagnosed with failed back surgery syndrome (FBSS), one older patient with lumbosacral radiculopathy who refused decompression, one cervical radiculopathy and Klippel-Feil syndrome, six with reflex sympathetic dystrophy (RSD), two with peripheral vascular ischemic disease, one with post-thoracotomy pain syndrome, one with leg pain following resection of angiolipoma, one with traumatic superficial peroneal neuropathy, and one with Pancoast's tumor. Fifteen patients were female and twelve were male. All were Caucasian. Their ages ranged from 27 to 84 years (mean:48). The average follow-up was 21 months (range: 48-6). All patients underwent a three day trial screening with Pisces-Quad/Resume epidural leads connected to a temporary external stimulator. An Itrel II System pulse-generator was internalized in each of the 24 patients who had successful trial (three cervical and twenty-one thoracic-lumbar). There was no morbidity. Pain reduction was sustained in 22 out of the 24 patients who continue to use the stimulator. The same number would choose to receive in an electrical stimulator again. Normalization or improvement in Quantitative Sudomotor Axon Reflex Test (Q-SART) and Thermography was documented in the patients with RSD. We conclude that rigid selection protocol can maximize the proportion of patients with intractable pain who are successfully treated with SCS. Strict neurosurgical technique eliminates infection risk. Hardware selection minimizes incidence of malfunction.

Management of patient-controlled analgesia: a comparison of primary surgeons and a dedicated pain service.

Although Patient-Controlled Analgesia (PCA) is routinely available in most hospitals in the United States, there appears to be little standardization regarding who provides this valuable service to postoperative patients. This study evaluates the differences in PCA management practices and patient outcomes between primary service (PS) physicians and acute pain service (APS) physicians. Over a 3-mo period, 40 patients prescribed PCA by PS physicians were prospectively studied without the knowledge of the physicians or nurses involved in PCA management. After collecting PS data, a proportionate stratified random sampling procedure was used to select 40 APS patients matched for gender, age, and type of surgery. Data regarding patient demographics, PCA prescription, changes in PCA orders, opioid consumption, reason for discontinuation of PCA, verbal analog scale pain scores, side effects, and post-PCA pain management were analyzed. Although pain scores were not different between groups, APS patients had fewer side effects, were more likely to receive a loading dose, had their PCA settings adjusted more often (P < 0.05), and used more opioid. PS patients were more likely to receive intramuscular medications after PCA discontinuation (P < 0.05). This study demonstrates potentially important PCA management differences between APS and PS physicians.

Effective management of chronic pain. The analgesic dilemma.

Despite the fact that pain is a common presenting complaint, its effective management remains an elusive goal surrounded by contradictions and controversy. In this article, Dr Stacey discusses the goals of chronic pain management and the treatment options available, with a focus on pharmacologic therapy and prescribing issues involving currently available analgesics.

Measuring treatment effects on repetitive lifting for patients with chronic low back pain: speed, style, and coordination.

The purpose of this study was to determine changes in the amount of work performed and lifting speed, style, and coordination during a repetitive dynamic-lifting task for patients with chronic low back pain (CLBP) after an intensive 3 1/2-week pain rehabilitation program. Subjects included 57 CLBP patients and an age- and gender-matched control group (n = 57). Patients' work indices increased by 71%, but remained significantly less than those observed for controls. Similarly, their lifting speed also increased significantly after treatment, but remained slower than the lifting speed of controls. Patients' posttreatment coordination indices, however, were not significantly different from those of controls. This finding suggests that treatment effectively normalized the dynamic lifting motion used by the patients. These findings, along with the basic kinematic patterns developed in this study, have important implications for determining improvements in functional capacity in the treatment of patients with CLBP.

Postoperative Guillain-Barré syndrome, arachnoiditis, and epidural analgesia.

BACKGROUND AND OBJECTIVES: A 58-year-old man developed progressive neurologic symptoms following a surgical procedure and postoperative epidural analgesia. METHODS: Neurologic evaluation, magnetic resonance imaging, computed tomography, and electromyography indicated the presence of both arachnoiditis and Guillain-Barré syndrome. The patient was treated with plasmapheresis and methylprednisone. RESULTS: The patient began to show clinical and electromyographic recovery but was lost to follow-up after his transfer to a rehabilitation facility. CONCLUSIONS: Anesthesiologists should be aware of the possible postoperative occurrence of rare neurologic disorders, both in patients who have received epidural analgesia and in those who have not, but they should not be deterred from using epidural analgesia by this isolated case.
