Question 1

swine GA risk

epidural anesth

what are swine under anesth prone to

Answer 1

malignant hyperthermia. extremely rare in potbellied pigs.

lumbosacral junction in swine. lido without epi common for swine blocks.
with xyla 2 mg/kg because lower will not work and higher can cause hind limb paresisfor 36h or more

**hypoventilation -> hypoxia. swine larynx sensitive to pressure or touch, even from saliva -> laryngospasm

hyperthermia. sweat glands do not function efficiently in thermoregulation**

Question 2

fasting swine

TKX protocol

atropine/ace/keta

atropine/xyla/keta

Answer 2

adults: no food 6-12h
piglets: no food 1-3h

telazol keta xyla mixed and IM. induction, 20-30 min anesth, ET intub poss, can repeat to extend duration

atropine and ace IM, then keta IM 20min later. minor and short procedures, 10-15 min anesth, if painful procedre must supp analgesia

Question 3

atropine/xyla/keta

xyla/telazol

intratesticular sodium pentobarb

Answer 3

atrop and xyla IM, then keta 10 min later. 10-15 min anesth

xyla then tela 5 min later IM. plane may be light and short duration. prolonged drowsiness post also poss

5 min, remove testes remove anesth

Question 4

inhalants

what may be safest anesth for pigs susceptible to malignant hypertherm

what can be used for arterial blood sampling in pigs and cathing for BP monitoring

Answer 4

avoid halothane, malignant hyperthermia. can use small or heavily sedated swine

IV thiobarbiturates ear vein

The auricular artery on the dorsal aspect of the ear pinna

Question 5

anesth HR

rec fluid admin rate

castration

herniorrhaphy

Answer 5

50-150 bpm, auricular and femoral arteries best locations

10 ml/kg/hr

In US and Canada, intact males cannot be marketed for meat because boar taint–distinct nasyy odor released during cooking, bad flavor to meat. begins with puberty onset

stagging = castrated after sexual maturity, odor disappears 3-4 wks after castration
