Q

How do rabbit teeth wear?

A

By grinding against themselves

17
Q

What condition is described below?
- Anything causing uneven wear
- Incisors: congenital, trauma, or secondary to cheek teeth malocclusion
- Molar: acquired (Vit D deficiency or inadequate/improper chewing motion)
- CS: may not be noticed until condition is advanced, may see injury from teeth growing into the mouth

A

Rabbit Malocclusion

18
Q

What is the difference between rabbit cheek teeth malocclusion versus rabbit malocclusion?

A

You DO see clinical signs (slobbering, dropping food, weight loss)
- Secondary CSs: nasolacrimal duct blockage, exopthalmos, facial swellings from apical swellings/abscesses
- Lip and dewlap dermatitis from slobbering

19
Q

What are ways to prevent malocclusion?

A
  • Don’t breed affected lines
  • Feed Timothy or other hay
  • Direct exposure to sunlight for Vitamin D
20
Q

Which pocket pets only have elodont front teeth?

A

Rats, Mice, Hamster, Gerbil, Prairie dog

21
Q

What pocket pets have all teeth as elodont?

A

Guinea pigs, chinchillas, degus

22
Q

In guinea pigs, what kind of clinical signs will you see in guinea pigs with malocclusion?

A

Weight loss, excess salivation, change in food choices and prehension, facial swelling, exophthalmos

23
Q

What are some physiological and anatomical considerations for anesthesia?

A

Small size, high metabolic rate, high surface area: volume ratio —> hypothermia, catecholamine-driven prey animals, underlying cardiovascular or respiratory dz, GI ileus, tympany, high O2 consumption rates, difficult intubation, difficult vascular access

24
Q

What routes can you go for vascular access?

A

IV, IO, SQ

25
Q

Blood volume is approximately how much of pocket pet BW?

A

~10%

26
Q

For pre-anesthetic preparation, what is not recommended?

A

Fasting

27
Q

Which veins do you access for blood collection?

A
  • Jugular, Cephalic, saphenous, marginal ear vein
  • Rats: lateral coccygeal vein
28
Q

Where do you place IO catheters? What gauge?

A

Proximal femur, tibia, and humerus (18-22G)

29
Q

Injury of the auricular artery leads to thrombosis and ischemic necrosis in what species?

A

Rabbits

30
Q

This type of anesthetic induction requires minimal physical restraint, reduces injury to animal and handler, environmental contamination and difficult monitoring

A

Induction chamber

31
Q

What kind of anesthetic induction is not done in restrained un-premedicated animals?

A

Mask induction

32
Q

What should you consider for airway management in rodents?

A

Palatal Ostium

33
Q

How can you check anesthetic depth in pocket pets?

A
  • Pedal withdrawal (toe/tail pinch)
  • Pinna reflex (pinch ear)
  • Corneal and palpebral reflexes
