Many laboratory investigations have established that peripheral tissue injury during surgery can trigger a prolonged state of spinal cord excitation. A reduction in neuronal thresholds in the central nervous system (CNS) is thought to amplify pain in postsurgical patients. Preemptive analgesia is an antinociceptive treatment targeted to block CNS hyperexcitability and leads to a reduced postoperative pain state. This treatment also has the long-term goals of facilitating rapid return to usual baseline function as well as decreasing the risk of chronic pain. However, despite numerous investigations, the clinical relevance of such treatment remains in controversy.
