Patient Pain Flashcards
What is pain?
an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage
acute pain
intense, but time limited
result of tissue damage or disease
disappears as injury heals
lasts less than 6 months
chronic pain
often begins as acute pain
not dissipate after a min. 6 months
high anxiety, helplessness due to lack of medical treatment
interferes with daily life
three sub categories of chronic pain
recurrent acute
intractable-benign
progressive
recurrent acute
cause by benign or harmless condition
repeated intense episodes separated by period w/out pain
intractable-benign
benign but persistent pain
crying levels of intensity, but never disappears
Progressive
pain often originates from malignant condition
continuing pain and discomfort
Pain worsens over time, as underlying condition worsens
what is pain mediated by
mediated by nociceptors
theories of pain
specificity theory
pattern theory
the gate control theory
specificity theory
separate sensory system for perceiving pain
specific sensory receptors for detecting pain stimuli
specific peripheral nerves and pathway to the brain
specific area within the brain for processing pain signals
pattern theory
no separate system for perceiving pain
pain results from the pattern or type of stimulation received by nerve endings
intensity of the stimulation is key determination of pain
strong and mild stimuli of the same sense modality produce different patterns of neural activity
limitations of ST
incorrect - no specific receptor cells in the body that only transfer information about pain
limitations of PT
- requires stimuli triggering pain must be intense
- pain can be experienced without tissue damage
- tissue damage can exist without pain
- both fail to account for the important role of psychology in the perception of pain
Gate Control Theory
- Psychological factors AND physiological factors
- Explains why the same event can be interpreted by different people as more or less painful
- Explains why sometimes pain is not experienced immediately
- Describes the individual as having some control over the experience of pain
three different methods on the assessment of pain
physiological
self-report
behavioural
