  1. Are pigs easy to restrain?
    • no they are very strong
    • a 40 pound pig is harder to handle Labrador retriever
  2. Why do we need to give pigs a higher dose of anesthetics?
    because they have a higher body fat %
  3. What kind of injections do give for anesthetics in pigs?
    • IM for sedation followed IV or IM for induction
    • IV is limited  and ears are really the only option
  4. Are pigs easy to intubate?
    no, can not see the larynx so it is a blind intubation
  5. Pigs can easily get malignant hyperthermia when under anesthesia.  What is this and what is another name for it?
    • acute severe hyperthermia associated with anesthesia, exertion, transportation or other stress
    • also called porcine stress syndrome
  6. Do we often do local or regional blocks in pigs?
    not frequently done due to conformation and high % body fat, but if we do do them then we do it the same way as we did for ruminants
  7. What kind of sedatives/premeds do we give to pigs?
    • anticholinergics
    • alpha 2 agonists
    • acepromazine
  8. What do anticholinergics do for pigs?
    • better at drying secretions in swine than in ruminants
    • prevents/treats bradycardia
    • GI stasis is not much of a concern in pigs
  9. What are the alpha 2 agonists that can be used in pigs and which one is the most commonly used?
    • xylazine
    • dexmedetomidine (dexdomitor)
  10. How do pigs react to xylazine?
    least sensitive and most resistant than other large animals so we use a higher dose
  11. How long does acepromazine take to work in pigs?
    20 - 30 minutes
  12. What can xylazine cause pigs to do?
    vomit
  13. What are the different inductions agents we can use for pigs?
    • thiobarbiturates (thiopental)
    • dissociates (ketamine and telazol)
    • GKX
  14. Which dissociative do we use the most commonly in pigs and why?
    ketamine because its cheaper than telazol
  15. How do we give the triple drip in pigs and how is it different than in ruminants?
    • 1/2 L bag of 5% guaifenesin, 5cc of ketamine, 5cc of xylazine
    • administer about 1ml/kg for IV induction or give to effect then CRI for maintenance (2ml/kg/hr)
    • we can put xylazine in the bag bc pigs aren't as sensitive to it as ruminants
  16. What are the different ways to maintain a pig on general anesthesia?
    • repeat doses of induction agents (1/2 initial dose of ketamine IM)
    • CRI of GKX
    • inhalants
  17. How is anesthesia different for pot belly pigs than for food animal pigs?
    • not held to the same economic concerns and can use more expensive drugs
    • pre-meds followed by mask induction 
    • can use propofol
