PY - 2016 T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - Acute pain is defined as pain that is caused by noxious stimulation due to injury, a disease process, or the abnormal function of muscle or viscera. Nociceptive pain, which entails four physiological processes (transduction, transmission, modulation, and perception), is usually implicated in acute pain. Posttraumatic, postoperative, obstetric pain, and acute medical illnesses, such as myocardial infarction, pancreatitis, and nephrolithiasis are various forms of nociceptive pain. Acute pain is typically self-limited, but when it persists beyond the usual course of an acute disease or after a reasonable time of healing (1–6 months), it is classified as chronic pain.
