Preliminary reports of continuous intraspinal morphine analgesia have been enthusiastic regarding the resultant cancer pain control. Reports of continuous intraspinal infusion have not documented the duration of useful analgesia, need for concomitant analgesic therapies, or complication rates. Thus, the overall outcomes and complications of six chronic intrathecal and eight epidural morphine infusions were analyzed in the first 14 cancer pain patients implanted with continuous intraspinal morphine infusion reservoirs at this clinic. ⋯ Three patients ultimately required neurolytic blocks. No clear difference was found in pain control requirements between epidural and intrathecal morphine infusion. No infection or respiratory depression occurred as a direct result of the intraspinal morphine implanted system.
