ICVA Exotic Animal Anesthesia 2

Question 1

Which inhalant anesthetic is most commonly recommended for reptiles due to its rapid induction and recovery profile?

Accepted Answer

Isoflurane

Answer

Isoflurane is preferred in reptiles because it provides smooth induction, stable cardiovascular effects, and rapid recovery compared to older agents.

Question 2

What is the primary concern when anesthetizing a chelonian (turtle or tortoise) regarding respiratory monitoring?

Accepted Answer

Ability to breath-hold voluntarily for extended periods

Answer

Chelonians can voluntarily breath-hold for prolonged periods, making respiratory rate an unreliable anesthetic depth indicator.

Question 3

Which analgesic class has demonstrated the least clinical efficacy in birds due to differences in opioid receptor distribution?

Accepted Answer

Mu-opioid agonists

Answer

Birds have a different distribution and density of mu-opioid receptors compared to mammals, making mu-opioid agonists less effective analgesics in avian patients.

Question 4

A ferret presenting for adrenalectomy requires premedication. Which combination is most appropriate?

Accepted Answer

Medetomidine and butorphanol

Answer

Medetomidine combined with butorphanol provides reliable sedation and analgesia in ferrets with a manageable cardiovascular profile.

Question 5

What is the recommended body temperature range to maintain during anesthesia in most lizard species?

Accepted Answer

25–35°C

Answer

Lizards are ectotherms and their metabolic and anesthetic drug metabolism is optimized within their preferred optimal temperature zone of approximately 25–35°C.
