Pain Flashcards
(21 cards)
anesthesia
absence of sensation, especially sensitive to pain
analgesia
decreased or absent sensation of pain
hyperalgesia
extreme sensitivity to pain
hyperesthesia
extreme sensitivity of one of the body’s sense organs, like pain or touch
allodynia
experience of pain from non-painful stimuli, like from light touch
dysesthesia
abnormal, usually unpleasant sensation to touch
hyperpathia
hypersensitivity to sensory stimuli, includes hyperesthesia, allodynia, and hyperalgesia
WHO 3-step pain ladder
1= mild ASA acetaminophen, nsaids 2= moderate codeine, hydrocodone, oxycodone 3= severe morphine, hydromorphone...
neuropathic
pain without a painful stimuli
complex regional pain syndromes
pain due t o peripheral nerve fiber injury but with uncertain pathophysiology, etc, phantom limb pain
neuralgias
nerve pain
radicular
pain radiating to the lower like due to compression injury or inflammation of a spinal nerve root, (herniated disk)
nociceptive
related to tissue injury/damage
idiopathic
unknown origin or cause
psychogenic
somatization disorders or hysterical reactions
acetaminophen (tylenol)
peripheral agent
inhibits prostaglandin synthesis in the CNS
- has antipyretic and analgesic properties
- little anti-Inflammatory
opiods
mimics actions of endogenous opiod peptides by interacting with opioid receptors (mu,delta, kappa)
-inhibits neurotranmitter firing = no pain
bisphosphonates
some pain relief for bone metastases by decreasing osteclast activity and formation
neuropathic agents
local anesthetics block transmission of pain signals from PNS to CNS
anticonvulsant agents
inhibit Na+ and Ca+ voltage gated channels, decrease nerve firing
Gabapentin is used often
NSAIDS
peripheral agent
Aspirin, ibuprofen, naproxen
inhibits synthesis of prostaglandins by inhibiting the COX enzyme
