LP 12: Pain & Comfort Flashcards
What are the consequences of poor pain management?
-Sleep deprivation
-Poor nutrition
-Depression
-Anxiety
-Agitation
-Decreased activity
-Delayed healing
-Lower overall quality of life
What is the Nature of Pain?
“Whatever the experiencing person says it is, existing whenever he/she says it does”
Highly subjective
5th vital sign
What are the 3 types of location of pain?
-Radiate
-Reffered
-Visceral
What is Radiate Pain?
Pain that spreads to other areas (Low back pain spreads to legs).
What is Reffered Pain?
Pain that appears to to arise in different areas of the body (cardiac pain is felt in left shoulder or arm)
What is Visceral Pain?
Pain that arises from organs or hollow viscera.
What is Acute Pain?
Sudden. Short term.
*<3months
*Mild to severe
*Resolves with healing
*Abnormal VS (increased RR,PR,BP) ->Sympathetic nervous system
What is Chronic Pain?
Prolonged. Long term.
*>3months
*Mild to severe
*Continues beyond healing
*Pt. appears depressed and withdrawn
What are the intensity types of pain?
*Mild 0-3
*Moderate 4-6
*Severe 7-10
What is the Etiology of pain?
*Physiological (Nociceptors)
- Somatic (paper cut; sprained ankle)
- Visceral (obstructed bowel)
*Neuropathic (Nerves damaged)
- Peripheral neuropathic pain
- Central
What is Threshold?
Least amount of stimuli needed for pain sensation.
What is Pain Tolerance?
Max amount of pain a person is willing to withstand.
What is Hyperpathia/Hyperalgesia?
Heightened responses to a painful stimuli (severe pain to a paper cut)
What is Allodynia?
When non-painful stimuli produces pain (light touch, contact with linens, wind)
What is Dysesthesia?
Unpleasant abnormal sensation (needles, pinds, itching, burning)
What is Sensitization?
Increased sensitivity of a receptor after repeated activation by a noxious stimuli
What is Windup?
Progressive increase pain.
Pain gets out of control.
What are Nociceptors?
The make up the physiology of Pain
-Transduction
-Transmission
-Perception
-Modulation
Transduction
Harmful stimuli trigger the release of biochemical mediators which sensitize nociceptors.
-Affect PNS.
-NSAIDs are used (Ibuprofen, aspirin, naproxen)
Transmission
Process of transmiting pain from site of incident to the brain.
Pain travels through the spinal cord to the brain.
Opioids/Narcotics are used
