AbstractSixty-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). Twenty-four of the 46 patients received pain relief without developing tolerance or side effects or experiencing mechanical failure of the application systems. 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.
