  1. nociception = 
    • typical acute pain 
    • detected by the peripheral receptors (nociceptrors)
  2. acute pain travels what pathways
    A fibers
  3. chronic pain travels what pathway
    c fibers
  4. nociception route
    • 1 - noxious stimuli (transduction)
    • 2 - impulse travels from spinal cord to brain (transmission)
    • 3 - impulse at the cerebral cortex (ouch)
    • 4 - modulation = neurons release neurotransmitters that block the pain impulse
  5. transduction = 
    • injured tissue releases chemicals that propagate pain message
    • action potential travels along afferent fibers to the spinal cord
  6. transmission = 
    pain impulse moves across synapse in spinal cord to travel to the brain
  7. perception of pain happens where
    cerebral cortex
  8. modulation = 
    neurons from the brain stem release neurotransmitters that block the pain impulse at the opiod receptors
  9. neuropathic pain = 
    • abnormal processing of pain message 
    • pain at neurochemical level
  10. viseral pain = 
    organ/abd
  11. deep somatic pain = 
    muscle and tendon pain
  12. cutaneous pain =
    pain on skin
  13. referred pain = 
    pain felt in a place other than where it originates 
  14. acute pain = 
    • short term 
    • self-limiting
    • follows predictable trajectory
    • dissipates after injury heals
  15. chronic pain =
    • continues for 6 months or longer
    • malignant (cancer) or nonmalignant
    • does not stop when injury heals
  16. question to ask about pain
    • OPQRSTU
    • onset
    • provocation
    • quality
    • radiate
    • severity
    • time
    • what does pt think it is
  17. joint pain objective data =  
    limited range of motion 
  18. muscle/skin objective pain data
    • color/swelling
    • masses/deformity
    • sensation changes
  19. abdomen pain objective data
    • contour/semetry
    • guarding/organ size
  20. acute pain behaviors
    • guarding
    • grimacing
    • vocalizations
    • agitation
    • stillness
    • diaphoresis
    • change in vitals
  21. chronic pain behaviors
    • bracing 
    • rubbing
    • diminished activity
    • sighing
    • change in appetite
    • prayer 
    • sleeping
  22. reflexive sympathetic dystrophy
    • when light touch causes a sever pain
    • follows trauma to a nerve
    • most common in 40-60 yo
  23. what are some common causes of pain in a aging adult?
    osteoporosis, chronic constipation, PVD, cancer, osteoarthritis, angina
  24. breakthrough pain =
    pain restarts or escalates before next scheduled analgesic dose
  25. nociception is
    the process whereby noxious stimuli are percieved as pain; central and peripheral nervous systems are intact.
