pain management Flashcards
physiologic effects of pain
hyperglycemia, increased cardiac workload, immune system dysfunction, altered coagulation, GI ileus, urinary retention, decreased lung volume and fatigue
psychological effects of pain
social isolation, disability and lost work productivity, decrease in quality of life, depression, and demoralization
pain is
“whatever the experiencing person says it is, exciting whenever he (or she) says to does
physiology of pain: four processes
transduction, transmission, perception, modulation
transduction
converts noxious stimuli to electrical impulses (move from periphery nociceptors to dorsal horn of the spinal cord), nociceptors are stimulated by release of histamine, lactic acid, bradykinin, prostaglandins, substance P, serotonin
nociceptors are stimulated by release of
histamine, lactic acid, bradykinin, prostaglandins, substance P, serotonin
transmission
A delta fibers, C fibers, reflex arc
perception
individual interpretation of stimuli, increased sensitivity to thermal pain and reduced subcutaneous lidocaine efficacy in redheads, adaptation
modulation
regulation or inhibitor of pain sensation, neuromodulators (endogenous opioid compounds) endorphins/ enkephalins
gate control theory
provides ideas for pain relief emphasizing multiple dimensions of pain; relationship between pain and emotions; sensory, emotional, behavioral, cognitive
types of pain: duration
acute, chronic/ malignant- nonmalignant
types of pain: source
cutaneous, somatic, visceral
types of pain: mode of transmission
referred
types of pain: etiology
nociceptive, neuropathic, psychogenic
a patient who has bone cancer is most likely experiencing which of the following types of pain?
somatic, pain is scattered throughout the bones, tendons and ligaments
cutaneous pain is
superficial. ex. paper cut
somatic pain is
diffuse/ scattered. ex. sprained ankle
visceral pain is
body organs due to stretch/ spasm. ex. cholangitis
