The pathophysiologic mechanisms for complex regional pain syndrome (CRPS) are complex and elusive. The proposed etiologic mechanisms for CRPS include inflammatory responses, peripheral or central sensitization, and sympathetic dysfunction. Anesthesia care of patients with CRPS is challenging. Treatments including physiotherapy, peripheral vasodilators, sympathetic blockade, analgesics, and other systemic medications can help optimize mobility, perfusion, and pain relief for affected patients.
