Terms in this set (36)
An unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in such terms
- International society for the study of pain
A vital, protective mechanism that permits us to live in an environment fraught with with potential dangers.
Rare cases of congenitally absent nociceptors show continuous environmental injuries and self mutilation usually resulting in death at a very young age
Pain which lasts beyond the ordinary duration for the tame that an insult or injury to the body needs to heal
Chronic pain syndrome
No longer a symptom but a disease state. A condition of chronic pain often disproportionate to physical findings, associated with interference in function or coping in daily life (professional, social)
Perception of nociceptive input in terms of tissue damage, either somatic or visceral
Arises from damage to body tissues. Well localized by variable in description and experience
Arises from viscera and is mediated by stretch receptors. Poorly localized, deep, full, and cramping, e.g. appendicitis, cholecystitis, pleurisy
Arises from abnormal neural activity secondary to disease or injury of the nervous system. Persists in the absence of ongoing disease.
Examples: diabetic neuropathy, trigeminal neuralgia, thalamic pain syndrome
Disturbance of function of pathologic changes in a nerve.
Mononeuropathy: one nerve
Mononueropathy multiplex: several nerves
Polyneuropathy: in symmetric bilateral nerves
Central pain syndrome
Abnormal CNS activity
Phantom limb, pain from spinal cord injury, post-stroke pain
Pain perceived at a site other than the site of tissue damage
Sympathetically mediated pain
Pain that is mediated or maintained by NE secreted by the S-ANS. Often due to nerve injury and associated with autonomic changes. A sympathetic nerve block (stellate ganglion block) terminates the pain
Non sympathetically mediated neuropathic pain
Peripheral nerve damage without autonomic changes.
Post-herpetic neuralgia, neuroma formation
Presence of physical symptoms suggesting a medial condition despite the lack of any organic physical findings. Symptoms cause significant functional distress or impairment. Do not appear under voluntary control. Make diagnosis w/ caution. Pain doesn't always follow the expected dermatomal pattern, neural plasticity can also alter the presence of persistent pain
Polysymptom disorders involving multiple organ systems and often accompanied by a belief that one is sick. High utilization of medical resources. presentation is often dramatic but vague, imprecise or inconsistent history
Pain, numbness, weakness is the triad. Often there is an unconscious conflict or motivation and a temporal relationship between a psychosocial stressor and onset of symptoms. 30% of patients eventually develop a diagnosable physical disorder.
Preoccupation with a disease state. Either fear that one has it or misinterpretation of bodily sensation/function leading to the belief that a serious condition exists. Causes significant functional distress/impairment.
Intentionally created on the part of the patient (producing or faking) in order to assume the sick role
Intentional production of factitious disease with conscious external motivation
A process by which pain becomes sustained by modulation of factors within the PNS or CNS
Derived from the opium poppy
Natural and synthetic derivatives, including opium
Substances that produce narcosis, legal definition includes opioids and cocaine
Drugs used in pain management that may or may not have intrinsic analgesic properties. However, they provide pain relief in certain pain syndromes or potentiate that common analgesics. Be clear with your patients why these drugs are being used.
Increasing doses are required to elicit the same initial effect
Withdrawal symptoms develop with abrupt withdrawal of the substance or antagonist administration
Primary chronic neurobiological disease with genetic, psychosocial, and environmental factors. Characterized by cravings, compulsive, uncontrolled use of a substance resulting in physical/psychological/social harm. Continued use of the drug despite negative consequences.
Pattern of drug seeking behavior of patients with pain receiving inadequate pain management that can be mistaken for addiction.
Pain due to a stimulus that does not normally provoke pain. Ex: wisp of cotton brushed over a painful area is perceived as painful
Increased sensitivity to stimulation, painful or otherwise, excluding special senses
Perception of more pain in response to a noxious stimulus than would normally be evoked by that stimulus
Explosive response to a normally painful stimulus
Abnormal sensation in the distribution of a nerve. May be spontaneous or evoked. Ex: light tapping over the wrist of a patient with carpal tunnel syndrome evokes electrical shocks in the median nerve distribution (Tinel sign)
Abnormal and unpleasant sensation in the distribution of a nerve
Absence of pain in response to a stimulus that would normally be painful. Or a decrease in pain/increase in pain threshold. Results when analgesics such as opioids are used
An agent that produces analgesia. May be a pharmacological agent such as an opioid, or a nonpharmacological method such as a TENS unit
