Pain
-
Sixty-two patients with intractable pain secondary to cancer of the pelvic organs were managed with intrathecal injections of morphine. Forty-six patients experienced pain relief from an initial test dose that ranged from 0.5 to 2.0 mg. In order to provide long-term pain relief, these 46 patients were further treated with repeated single injections (14 patients), external catheter (28 patients), or implanted pump (4 patients). ⋯ When side effects developed, they were generally itching, sphincter disorder and somnolence. No serious respiratory depression was noted. Intrathecal morphine offers a hopeful alternative to systemic narcotics or ablative neurosurgical procedures in the management of terminal cancer pain.
