Intraspinal analgesic delivery, through an implanted infusion pump, has been considered one of the most important breakthroughs in pain management over the past 3 decades. The discovery of specific opioid receptors in the spinal cord in 1970s, made it possible for spinal application of opioid, to obtain spinally mediated analgesia. By infusing small amount of opioid directly into the cerebrospinal fluid, in close proximity to the receptor sites in the spinal cord, one is able to achieve the spinally mediated analgesia, sparing some of the side effects caused by systemic opioids. Intraspinal drug delivery therapy i.e., “intrathecal pain pump” has been increasingly utilized since 1980s in patients with intractable, chronic, nonmalignant pain. However, it has been increasingly recognized that intraspinal drug delivery therapy may also be associated with complications and side effects.
