AbstractEpidural opiates were administered to 139 patients with pain due to malignant diseases via a chronic indwelling catheter inserted percutaneously. So far, 9,716 days of treatment can be evaluated. In 87% of the patients whose pain previously could not be controlled with conventional analgesic approaches, epidural opiates resulted in remarkable pain relief. With a mean daily dose of 15.6 mg morphine (range 2-290 mg) or 0.86 mg buprenorphine (range 0.15-7.2 mg) half of the patients could be treated as outpatients. The mean duration of therapy was 72 days (range 1-700 days), 26 catheters being in place for more than 100 days and one catheter being in place for 510 days. Two severe side-effects (meningitis) were observed, both patients being free of symptoms after catheter removal and antibiotic therapy. Epidural opiates proved to be a valuable method of pain control in terminal illness. The method should be reserved for those patients, for whom oral opiates fail to produce effective pain relief.
