Effective Perioperative Pain Control Reduces Hyperalgesia – MM1504
Pain arising from impending or actual tissue injury has an important physiological role, protecting the body from injury and promoting healing once injury has occurred. However, if pain persists in the absence of ongoing nociceptive input from the periphery, or exceeds the pain normally caused by ongoing nociceptive input, it loses its physiological function. Pain of this nature is therefore called maladaptive or dysfunctional pain. Dysfunctional pain is thought to arise from altered processing of nociceptive information in the central nervous system.
