Constant infusion of morphine for intractable cancer pain using an implanted pump.
In the past, pain control for chronic pain syndromes using narcotic infusion has been carried out primarily via the intrathecal (subarachnoid) route. This report presents one of the first large series of terminally ill cancer patients with intractable pain treated with continuous epidural morphine infusions by means of implanted pumps and epidural spinal catheters. The purpose of the study was to demonstrate that the epidural route is effective with minimal complications, and that screening with temporary epidural catheter infusions results in a high rate of subsequent pain relief. ⋯ One patient developed apparent drug tolerance and three patients required further catheter manipulations. This series strongly suggests that significant reductions in cancer pain can be obtained with few complications and a low morphine tolerance rate using chronic epidural morphine infusion. Anesthesiology and psychiatry input, along with temporary catheter infusion screening and quantitative pain evaluations using analog scales, are essential.

Effect of bullet removal on subsequent pain in persons with spinal cord injury secondary to gunshot wound.
The prevention or minimization of future pain is often cited as a reason for removal of the bullet from patients who have incurred a spinal cord injury secondary to a gunshot wound. In an attempt to examine this assumption, multimodal pain ratings were recorded for 14 patients with spinal cord injury due to a gunshot wound in whom the bullet was still present, 14 neurologically matched patients with spinal cord injury due to a gunshot wound in whom the bullet was removed, and 28 control patients with spinal cord injury unrelated to a gunshot wound who were neurologically matched to the first two groups. ⋯ The location of the bullet and the type of pain that subsequently developed were not correlated with the initial decision to surgically remove the bullet. Implications for further study and clinical practice are discussed.
