Pain Management In Veterinary Medicine Flashcards
What is the definition of pain?
“ PAIN is an unpleasant sensory and emotional experience associated with, or
resembling that associated with, actual or potential tissue damage
What is transduction?
Conversion of a noxious stimuli to an action potential at the level of the nociceptors
What is projection?
Nociceptive info transported into the brain
What is perception?
Brain’s process of integrating the nociceptive info or the conscious processing of pain
How would you classify acute pain?
- Results of trauma, surgical or infectious events
- Starts abruptly, resolves in days/weeks
- Self-limiting, biological purpose
How would you classify chronic pain?
- Persists beyond normal time of healing/absence of healing
- > 1-3 months in duration
- Disease
What is somatic pain?
Well localised, aching, sharp, intense
* Superficial or Deep
What is visceral pain?
- Dull, diffused, poorly defined sensation
- Referred pain
What is neuropathic pain?
Caused by injury of the somatosensory system (i.e., peripheral nerves, spinal cord or brain)
What is allodynia?
Pain sensation in response to a non painful stimulus
What is hyperalgesia?
Exagerated pain sensation in response to a normally painful stimulus
What is the facial pain scale?
Observation of the subject from a distance
* Different action units
* No direct interaction
* Developed in many species
Why should we treat pain?
Avoiding
* stress reactions
* Delayed wound healing
* Inflammation
* Decreased appetite
What is pre-emptive analgesia?
Administration of analgesics drugs BEFORE the onset of the noxious stimulus
* Reason to administer analgesic drugs in premedication
What is multi-modal analgesia?
Use > than one pharmacological class of analgesic medications targeting different
receptors along the pain pathway
* Produce superior analgesia
* To reduce individual class-related side effects
