Long-term use of subarachnoid clonidine for analgesia in refractory reflex sympathetic dystrophy. Case report.

BACKGROUND AND OBJECTIVES: A case is presented of intractable reflex sympathetic dystrophy resistant to all other types of treatment. METHODS: Twice daily subarachnoid clonidine was used to manage the symptoms via an implanted drug delivery system. RESULTS: The patient has successfully administered his own subarachnoid clonidine for over 18 months with no signs of tolerance or toxicity. CONCLUSIONS: Continuous subarachnoid clonidine may offer a solution to the management of some cases of intractable reflex sympathetic dystrophy.
