Pain Management Flashcards
Define: Algesia
Increased sensitivity to pain
Define: Algogenic
Pain producing
Define: Allodynia
A normally non harmful stimulus is perceived as painful
Define: Analgesia
The absence of pain in the presence of a normally painful stimulus
Define: Dysethesia
An unpleasant painful abnormal sensation, whether evoked or spontaneous
Define: Hyperalgesia
A heightened response to a normally painful stimulus
Define: Neuralgia
Pain in the distribution to a peripheral nerve(s)
Define: Neuropathy
An abnormal disturbance in the function of a nerve(s)
Define: Parasthesia
An abnormal sensation, whether spontaneous or evoked
What is the time length to be termed acute pain
< 1 month
What is the time length to be termed chronic pain
> 3 months
What is nociceptive pain
Stimulation of SPECIFIC nociceptors
- Somatic
- Visceral
What is non-nociceptive pain
- Neuropathic
- Inflammatory
Describe Somatic pain
- Identifiable _____
- Tissue damage is from…
- How is the pain described?
Identifiable focus
Tissue damage – chemical release modulates pain
Well localized, sharp, hurts at area
Describe Visceral pain
- localized of diffuse?
- How is pain described?
- Associated with what autonomic reflexes
- What is an example
Diffuse, referred
Dull, cramping, squeezing
Autonomic reflexes - nausea, vomiting, diarrhea
Ex. Distention of organ capsule, obstruction of a hollow viscus
Neuropathic pain - damage to peripheral or central neural structures resulting in…
an abnormal processing of painful stimuli
Neuropathic pain is dysfunction of the…
central nervous system
How is neuropathic pain described
Burning, tingling, shock like
Describe the process of inflammatory pain
Sensitization of the nociceptive pathway from multiple mediators being released at the site of the tissue inflammation WITHOUT neural injury
What is the order of nociceptive pain transmission
Transduction, Transmission, Perception, Modulation
Define: Transduction
Stimuli is converted to action potential
Define: Tranmission
Action potential conducted through nervous system
First-, second-, third-order neurons
Define: Perception
Integration of painful input into the somatosensory and limbic cortices
Define Modulation
Altering afferent transmission along pain pathway
