Intrathecal octreotide for relief of intractable nonmalignant pain: 5-year experience with two cases.
Somatostatin is distributed in the substantia gelatinosa in the dorsal horn of the spinal cord, and its application has been found to produce an inhibitory effect on nociceptive neurons. Although intraspinal administration of somatostatin-14 produces pain relief in patients with cancer and in postoperative patients, its short half-life limits its clinical usefulness. ⋯ This article describes the 5-year clinical course of two patients receiving intrathecal octreotide for severe, intractable nonmalignant pain. Included in this description are the results of blinded, randomized "N of 1" trials conducted in each of these patients.
