NRSG 1030 Unit 11 Pain
pain - ANS-an unpleasant sensory and emotional experience associated with actual or
potential tissue damage
pain is - ANS-the most common reason people seek medical care and is a subjective
experience; significantly interferer's with quality of life
Cutaneous or superficial pain - ANS-arises in the skin or the subcutaneous tissue;
burning pain
visceral pain - ANS-caused by stimulation of deep internal pain receptors; abdominal
cavity, cranium or thorax, not well localized. Presents as tight, pressure, crampy pain
deep somatic pain - ANS-originates in the ligaments, tendons, nerves, blood vessels,
and bones; localized and presents as achy or tender
radiating pain - ANS-starts at the origin but extends to other locations
referred pain - ANS-occurs in an area that is distant from the original site
phantom pain - ANS-pain that is perceived to originate from an area that has been
surgically removed, burning, tingling, stabbing - gets better over time
psychogenic pain - ANS-refers to pain that is believed to arise from the mind
Nocieptive pain - ANS-most common type of pain experienced, occurs when pain
receptors (nociceptors) respond to stimuli that are potentially damaging
-may occur from trauma, surgery or inflammation
VISCERAL or SOMATIC
neuropathic pain - ANS-a complex and often chronic pain due to injury to nerves;
repeated transmission of pain signals even in the absence of painful stimuli
nerve injury can originate from a variety of conditions such as poorly controlled
diabetes, stroke, tumor, alcoholism, amputation, viral infection
(burning numbness, itching, and "pins and needles"
acute pain - ANS-short duration and rapid onset, varies in intensity and can last up to 6
months
, -generally from injury or surgery and is protective in nature
chronic pain - ANS-pain that lasts longer than 6 months, interferes with daily activities
-may experience periods of remission and exacerbation and often viewed as
insignificant
-may lead to withdraw and depression
intractable pain - ANS-both chronic and highly resistant to relief and should be
approached with multiple methods of pain relief
characteristics of pain - ANS--Sharp -Aching
-Throbbing -Dull
-Cramping -Shooting
-Burning -Electric like - searing
periodicity of pain - ANS-episodic, intermittent, constant
intensity of pain - ANS-Mild, distracting, moderate, severe, or intolerable
transduction pain - ANS-nociceptors become activated by stimuli:
-mechanical: external forces that result in pressure or friction against the body
-thermal: exposure to heat or cold
-chemical: internal or external
transmission pain - ANS-peripheral nerves carry the pain message to the dorsal horn of
the spinal cord
a-delta fibers and c-fibers
a-delta fibers - ANS-transmit FAST sharp, intense but short lived pain of immediate
injury
-large, myelinated fibers
pain perception - ANS-recognition and definition of pain in the frontal cortex
pain threshold - ANS-number and intensity of stimuli necessary to produce pain
pain tolerance - ANS-duration or intensity of pain a person can endure
