ReviewRole of epidural and intrathecal narcotics and peptides in the management of cancer pain.
The spinal administration of opioids may provide analgesia of long duration to patients with bilateral or midline lower abdominal or pelvic cancer pain. However, cross-tolerance to orally and parenterally administered narcotics and the rapid development of tolerance to spinal narcotics have limited their usefulness. ⋯ Further clinical and pharmacokinetic studies are required to provide the information regarding: the optimal opioids for use as spinal analgesics; equieffective dose ratios of spinal opioids in comparison to parenteral or oral opioids; strategies useful to forestall the development of tolerance of spinally administered opioids; the analgesic efficacy of this therapy in opioid-tolerant patients; and the role of spinally administered nonopioid analgesics in the management of cancer pain in the tolerant patient. These questions will need resolution before this therapy can be recommended for routine use in the management of cancer pain.

Modern techniques available for the relief of pain following major surgical procedures or trauma in childhood receive scant attention in pediatric surgical textbooks. A range of options for pain relief have been offered to children in our hospital, which include: regional analgesia; appropriate use of intermittent intramuscular narcotic injections; and variable-rate intravenous narcotic infusions. Since 1982 regional analgesia has been used in more than 2,000 patients following operations on the penis and in the inguinoscrotal region. ⋯ Assessment of effective pain relief has been made on the basis of observation and comment by parents and patients and by medical and nursing staff. The steady increase in demand for the use of this technique is an index of its value. It is concluded that there is a real need to improve pain relief for children by better education of medical and nursing staff and inclusion of this important subject in pediatric surgical text books.

Randomized Controlled Trial Clinical TrialContinuous-plus-on-demand epidural infusion of buprenorphine versus morphine in postoperative treatment of pain. Postoperative epidural infusion of buprenorphine.
In a randomized, double-blind study, buprenorphine was compared with morphine in the treatment of pain after major abdominal operations by means of continuous-plus-on-demand epidural infusion for constant analgesia. The patients received bolus epidural injections of 0.15 mg buprenorphine or 2 mg morphine-HCl prior to an on-demand epidural infusion of 0.03% buprenorphine or 0.25% morphine HCl at a basal rate of 0.06 ml/h. ⋯ Under the treatment, no discomfort or side-effects necessitating treatment occurred. We conclude that buprenorphine is a useful substitute for morphine in the treatment of pain after major abdominal operations by continuous-plus-on-demand epidural infusion, and that the relative analgesic potency ratio of epidural buprenorphine is 8.

This study used behavioral assessment techniques to analyze pain in osteoarthritis (OA) patients. Eighty-seven OA patients having chronic knee pain served as subjects. Pain behavior was evaluated using a standard observation method and functional impairment was assessed using the Arthritis Impact Measurement Scales. ⋯ Patients receiving disability support payments were much more functionally limited than those not receiving this financial support. Patients scoring high on the Pain Control and Rational Thinking factor of the CSQ were much less functionally impaired, walked a 5 m course more rapidly and moved from a standing to a sitting or reclining position more quickly than patients scoring low on this factor. The implications of these results for behavioral treatment of OA knee pain are discussed.

The concept of psychogenic pain is discussed and reviewed from multiple theoretical perspectives. The validity of psychogenic pain disorder as a clinical diagnosis is also examined, as are regional pain syndromes such as psychogenic abdominal, facial, pelvic, chest, and headache pain. The term "psychogenic pain" is considered to have limited clinical or diagnostic usefulness and the preferred term "idiopathic pain syndrome" used in DSM-III-R is advocated.
