[Physiological Basis of Pain Mechanisms for Pain Management].

Physician anesthesiologists should ensure a future leadership position in perioperative medicine and pain medicine. In order to establish the missions, anesthesiologists need to know how to relieve pain in surgical patients, critically ill patients and patients with cancer and non-cancer chronic pain. Thus, anesthesiologists should realize physiology of pain representation from pain management I will review physiological basis of pain mechanisms in this manuscript which includes 1) evolutional aspect of pain perception, 2) transduction of noxious stimuli, 3) the types of nociceptors and conduction of noxious stimuli, 4) the ascending pathway of pain and central modulation of pain, 5) the descending inhibitory pain system, and 6) various types of pain. Finally, anesthesiologists should manage pain from physiological basis of pain mechanisms.
