HPM Questions Flashcards
What are the components of Total Pain?
Physical, Psychological, Social, and Spiritual
What is acute pain?
Occurs suddenly due to illness, injury, or surgery, that is generally short-lived that resolves as the acute illness heals
What is chronic pain?
Pain that lasts longer than the expected healing process (3 months for IASP), and that affects a person’s activities of daily living
What is nociceptive pain?
Arises from actual or threatened damage to non-neural tissues due to activation of nociceptors
What are common symptoms of somatic nociceptive pain?
Arises from bone, joint, muscle, skin, or connective tissue that is well-localized, aching, and throbbing
What are common cymptoms of visceral nociceptive pain?
Arsises from visceral organs (such as the GI tract), that is aching if related to capsular pain or poorly localized cramping if due to hollow viscus organ pain
What are the stages of nociceptive pain?
Transduction -> Conduction -> Transmission -> Perception -> Modulation
What are the characteristics of pain conducted by C-fibers?
C-fibers are small, unmyelinated, slow-conducting fibers that transmit dull, poorly localized, diffuse, burning/aching pain, and are sensitive to mechanical, thermal, or chemical stimuli
What are the characteristics of pain conducted by A-delta fibers?
A-delta fibers are large, myelinated, fast-conducting fibers that transmit well-localized, sharp pain, and are sensitive to mechanical and thermal stimuli
What are the characteristics of pain conducted by A-beta fibers?
A-beta fibers conduct non-noxious input (i.e., touch), and do not transmit pain signals
Which of the stages of nociceptive pain is not responsive to drug therapy?
Perception
What is an example of transduction of pain?
Nociceptors translate physical stimulus into an electrical signal and action potential
What is an example of conduction of pain?
Pain impulse traveling up or up to the spinal cord
What is an example of transmission of pain?
Transfer of an action potential from one neuron to the next
What is an example of perception of pain?
The conscious experience of pain
What is an example of modulation of pain?
Inhibiting descending pain impulses
What medications help reduce the transduction of pain signals?
NSAIDs, anticonvulsants, Capsaicin, Lidocaine, and TCAs
What medications help reduce the conduction/transmission of pain signals?
Opioids (endogenous and exogenous), Gabapentin, Pregabalin, Ketamine, and anticonvulsants
What medications help reduce the perception of pain signals?
None
What interventions help reduce the perception of pain signals?
Relaxation and guided imagery
What medications help reduce modulation of pain signals?
Opioids, Tramadol, Tapentadol, TCAs, SNRIs, and Baclofen
What processes lead to the development of neuropathic pain?
Abnormal nerve regeneration, increased expression of membrane sodium channels, disinhibition of the modulatory process, or decreased expression of mu-opioid receptors
What is allodynia?
Pain from a non-painful stimulus, such as touch
What pain assessment tool has been validated for patients with advanced dementia?
PAINAD – a 5 item observational tool
