Q

How does pentobarbitol work?

A
  • binds gaba receptors -> CNS depression
  • inhibits glutamate -> nerve depolarization in voltage activated calcium currents
  • loss of respiration, then brain dead in 73-261 secs, heart beat stops, brainstem reflexes stop, ECG activity will be the last to go

Q

How are KCl & Mg salts used in euthanasia for horses?

A
  • animal needs to be anesthetized prior in injection to be considered humane
  • powder is dissolved in warm water & rapidly injected IB
  • not a controlled substance, not environmentally toxic
  • KCl: cardiotoxic, colonic spasms
  • MgCl, MgSO4: suppression of neural activity

Q

How does intrathecal lidocaine work for euthanasia in horses?

A
  • 2% lidocaine hydrochloride administered at the atlanto-occipital space under general anesthesia
  • direct anesthetic effect on neural structures
  • halts brainstem function (breathing stops immediately)
  • loss of brain electrical activity in up to 226 seconds
  • heart stops in ~10 mins

Q

What is positive about using lidocaine for anesthesia?

  • inexpensive
  • readily available
  • drug residues in meat are not toxic to scavengers

Q

How do you administer intrathecal lidocaine?

A
  • anesthetize the horse
  • AO tap w/ 18g spinal needle or catheter stylet
  • 30-60 mL of CSF removed prior to injection (reduces pressure for ease of injection)
  • administer 30-90 mL of 2% lidocaine
17
Q

Where do you administer a gunshot or captive bolt in a horse?

A
  • just above the point of intersection of the lines drawn from the medial canthus of the eye to the middle of the opposite ear
18
Q

What is an alternative method to euthanize a horse?

A
  • laceration of the aorta via rectal palpation
  • difficult & dangerous
  • only perform if the horse is already down
19
Q

How do we confirm death in a horse?

A
  • absence of movement, absence of auscultable heartbeat & pulse, absence of respiration, fixed & dilated pupil, lack of corneal blink reflex
20
Q

how do we dispose of horse carcasses?

A
  • burial, landfill, rendering, cremation, chemical digestion
  • pentobarbitol is toxic so may not be accepted at rendering facilities & needs to be buried 6 feet deep
21
