pain factors
age, sex, race, gender, socioecon class,
genetics, past trauma, undrlying mental health, co-morb.
emotional response pain
fear and depression
vital sign response pain
inc heart rate, bp and respir rate
acute pain
localized, < 3-6 mon, follows injury, HAS biological purpose
result tissue damage
chronic pain
time-limited or lifetime
inc resistance versus diff pain modalities
no bio purpose
cancer, osteoarth, peripheral neuropathy
breakthrough pain
chronic pain w/ acute exacerbations
nociceptive pain
physiologic- tissue injury
nocioreceptors in skin, bone, musc signal to spinal cord
neuropathic pain
pathophysiologic- damage to PNS or CNS
chronic
ex. diabetic neuropathy
numbness and tingling
somatic v visceral pain
somatic- skin, bones, muscles
visceral- organs
nociception processes- transduction
stimuli activate nociceptors
act neurons, sent sc, brain and received by sensory cortex
prostaglandins
responsible for pain and swelling
produced when COX inhib act on arachdonic acid
nociception processes- transmission
couples w/ transduction to get signals to brain
nociception processes- perception
altering factors for pain- imagery, distraction
nociception processes- modulation
process that changes/inhib signals in spinal tract via neurochem
ex. anti-depres.
