PY - 2015 T2 - Atlas of Pain Medicine Procedures AB - The presence of abundant opioid mu receptors in the dorsal horns of the spinal cord was discovered in the 1970s. Subarachnoid injection of morphine was soon utilized to control cancer pain. Since intrathecal delivery of opioids provides direct access to the mu receptors, a much lower dose can achieve analgesia than by other routes of delivery. Thus, significant activation of systemic mu receptors, such as occur in the gut, is avoided thereby reducing unwanted side effects of opioid therapy such as constipation. The first clinical use of an implanted intrathecal drug delivery system (IDDS) was described in 1981. Introduction of effective bacteriostatic filters allowed safe long-term infusion. By 1991, commercially available fully programmable implanted IDDS became available (Medtronic, Inc, Minneapolis, MN).
