Why was “emotional” added as an amendment to the IASP’s definition of pain?
- original definition did not account for non-verbal patients
- VERBAL DESCRIPTION IS ONLY ONE OF SEVERAL BEHAVIOURS to express pain (inability to communicated does not negate the possibility that a human or nonhuman animal experiences pain)
- although pain usually serves as an adaptive role, it may have adverse effects on function & social & physiological well-being
how are pain and behaviour associated?
- pain is not just about how it feels, but also how it makes you feel
- personal experience
- affected by past experiences
- behaviour is the most sensitive and specific way to assess pain
What are the limitations of the relationship between pain and behaviour?
- not all animals display pain-related behaviour
- assessing pain behaviour is difficult in stressed and sick animals
What was the effect of neonatal circumcision on the pain response during subsequent routine vaccination?
- used to not use pain control in neonates b/c they believed their pain pathways were not fully developed yet
- past experiences of having past non-treated pain leads to a greater pain response in the future
What are some things to be aware of when assessing spontaneous pain behaviours?
- pain is almost always associated w/ changes in normal animal behaviour
- there is a difference btwn acute and chronic pain
- knowledge of the animal’s normal behaviour is beneficial
- the owner’s assessment can be a valuable aid
- assessing pain behaviour can be difficult in situations of chronic pain (this requires information from O)
- influenced by stress, anxiety, fear, sedation
