=Management of Complex Regional Pain Syndrome Type 1 with Barbiturate Coma Therapy-A case report-Tae Kyu Park, M.D., Kyung Ream Han, M.D., Dong Wook Shin, M.D., Young Joo Lee, M.D., and Chan Kim, M.D.Pain Clinic, Department of Anesthesiology and Pain Medicine, Ajou University Hospital, College of Medicine, Ajou University, Suwon, KoreaAlthough various treatments for complex regional pain syndrome (CRPS) have been proposed, no well recognized treatment for CRPS has been established. Herein, a case using barbiturate coma therapy for the refractory pain management of a 24-year-old male patient, who suffered from constant stabbing and burning pain, with severe touch allodynia in the left upper extremity following blunt trauma on his forearm is described. Interventional treatments, including permanent spinal cord stimulation and large doses of oral medications, were performed. However, the pain could not be controlled, which lead to frequent emergency room treatment for about 1 month prior to his therapy. He then underwent barbiturate coma therapy due to the uncontrollable pain, with repeated sedation therapy due to his outrageous behavior. His pain became increasingly tolerable and the allodynia was markedly decreased after 5 days of coma therapy. (Korean J Pain 2006; 19: 213 217)
