Fourteen patients were implanted with drug pumps to provide chronic epidural or intrathecal morphine to relieve pain due to cancer. A new programmable pump was used in 7 of the patients and a constant infusion device was used in the other 7 patients. Results, judged by subjective pain reports (on a 0 to 10 scale), decrease in oral narcotics, and change in activity level, were excellent in 8 patients, good in 5 patients, and poor in one patient. The programmable device has the obvious advantage of being able to vary dose according to patient need and requires less frequent refilling. Four programmable pump failures occurred, two requiring replacement.
