Pain

Epidural and intrathecal techniques are well established techniques in cancer pain. However, several questions remain unresolved. The several problems of long-term spinal opioid treatment in advance cancer patients were reviewed. ⋯ Different ranges of technical complication rates have been reported in the literature, most of them being associated with epidural catheters. Subcutaneous tunneling and fixation of the catheter, bacterial filters, minimum changes of tubings, careful exit site care weekly, site protection and monitoring of any sign of infection to prevent infection, and training for family under supervision, are recommended. Areas for additional research include the use of spinal adjuvants, the ideal spinal morphine-bupivacaine ratio. methods to improve spinal opioid responsiveness and long-term catheter management with appropriate home care programs.
