Exotic anaesthesia
- Pre anaesthetic considerations
- Fasting
- REPTILES
- Insectivores: 24 hours
- Snakes: 2 days (reduces
pressure on heart &
lungs)
- Chelonians: 30mins-1 hour
- Insectivores: 24 hours
- BIRDS (to ensure crop is empty)
- <100G: 30 mins
- 100-300g: 1 hour
- >300g: 8-10 hours
- Bird of prey: 12 hours
(make a cast ??)
- <100G: 30 mins
- MAMMALS
- Can vomit: Depends
largely on animal
(Ferrets = 2- 4hours)
- Can't vomit: 30mins-1
hour (ensure mouth is
empty)
- Can vomit: Depends
largely on animal
(Ferrets = 2- 4hours)
- REPTILES
- Patient assessment
- REPTILES
- Recommend
warming prior to
anaesthetic
- Recommend
warming prior to

- Measure: Accurate weight, HH,
RR, Temp & blood pressure
- Clinical signs present? -
assess from a distance if poss
- Prey species - may be none

- Birds
- High metabolic rate
- This means that tissue oxygen
reserves will be used up rapidly
- This means that tissue oxygen
reserves will be used up rapidly
- Don't starve for
prolonged periods
- Due to high metabolic rate - hypoglycaemia
- Due to high metabolic rate - hypoglycaemia
- No diaphargm - Rely on keel
movement only
- Air sac system
- Air sacs are NOT involved in
gas exchange - rather act as a
"bellows" for the lungs
themselves, allowing
unidirectional air movement &
ventilation,
- However - in tracheal obstruction the caudal
thoracic air sacs can still be used to provide
oxygen to the animal
- Much more efficient than mammals as there is little to no
residual air left within the lungs during ventilation = more
oxygen content available to body
- However - in tracheal obstruction the caudal
thoracic air sacs can still be used to provide
