Equine Anesthesia Flashcards
why is anesthesia mortality high in horses
-prey animals, run away
-myopathies bc of size
-prone to hypotension, hypoxaemia
prep for anesthesia
-fast (8h)
-IV catheter
-remove shoes
-mouthwash
-AB + anti-inflammatories
who should you not give ACP to?
foals,
hypovolaemic bc of vasodilation (colic),
stallions bc of priapism
how long before sedation to give ACP
30m (anxiolytic)
alpha 2 agonist - used for sedation or TIVA?
either
why urinary catheter w alpha 2 agonists
increase urine production
adverse effects of alpha 2 agonists
bradycardia
low RR
arrhythmia
general example for each multimodal analgesia approach:
transduction
transmission
modulation
transduction - NSAID
transmission - local
modulation - opioid
flunixin vs phenylbutazone:
which is visceral, which is somatic
flunixin is visceral
phenylbutazone is somatic
what age should not get alpha2 agonist
under 6 weeks foals
what anesthesia protocol can you give to foals under 6 weeks
midaz + butorphanol
propofol
main induction protocol
ketamine + a benzodiazepine
maintenance protocol: TIVA pros and cons
pros: cheap, good DV, good recovery if short
cons: hard to maintain depth, hard to give O2 in field, bad for 90+ min procedures
TIVA protocol for short (15-20m)
ketamine + (a2agonist, benzodiazepine, or butorphanol)
TIVA protocol for 20-90m
ketamine +
a2 agonist +
muscle relaxant
