Effective Sufentanil Intrathecal Pump Treatment in a Patient With Refractory Complex Regional Pain Syndrome: A Case Report.

Treatment for CRPS includes pharmacotherapy, sympathetic nerve block, and/or various surgical procedures. However, some patients may receive little benefit from these treatments with persistent severe pain despite undergoing treatment. Thus, novel treatments have been attempted to lessen CRPS-mediated pain. We present a case where one of these unconventional therapeutic approaches was utilized involving the administration of sufentanil through an intrathecal pump providing effective pain reduction in a patient with CRPS.
