- HR - 180-300
- T - 38.5-40
- GI - 2-4/min
what might exopthalmous in a rabbit suggest
thymoma (partic if increases when you lift it)
why can the lacrimal duct get so easily blocked
2 bends - px-maxillary and cd incisors
what might an ear base swelling suggest
OE (partic if a lop-eared rabbit) - pressure build up, TM might pop!
what cheylietalla spp do rabbits get
c. parasitovorax
what gauge is suitable for IV
24-26G
what needle is suitable for IO
1.5inch spinal needle and 18-22G
what local ana do you use in rabbits
lignocaine 2% (SC, IM, Intra-periosteum)
what type of drug would you use for premed
A2 AGONIST + KET fentanyl + fluanisone med + ket + buprenorphine xylazine diazepam midazolam
how often do you need to flush an IO catehter
3x/d AND before and after any medication
how much IM med can you give
1ml max
how much SC inj vol can you give
100ml/5kg rabbit — in different places (if fluids for example)
how small do nebulisation droplets have to be to reach LRT
<5um
how often do you nebulise
3-4x/d, for 10mins
which is the best v for blood sampling
lat saphenous - position and size are good
when inserting a naso-lacrimal cannular, desc the basic method
- evert lower eyelid
- ventral punctae
- V-M direction
- use 20-27G cannular (depending on rabbit size)
what would use use to sedate a rabbit
midazolam
alfazalone
what do you use to euthanase a rabbit
pentobarb - I/v. use a catheter
what are the agonal actions which may shock O
sneezes
agonal gasps
urine voiding
muscle twitches
why would you give a rabbit a barium meal
if recurrent GI stasis
what is there in the thorax which might make you worry abour a mass
lots of fat
should rabbit intestines be gassy
yes
is there normally sludge in bladder
yes often - though do ask more q about diet
what are rabbits vacc against
myxomatosis
rabbit haemaorragic disease 1 (and know 2 )
- novibac = RHD 1 + myxi
- felivac = RHD 1 +2 + myxi
what is the difference bw RHD1 and 2
RHD 1 - kill adults; kittens survve; fast incubation
RHD 2 - kill all, BUT slower incubation (3-9d) so more transmission. European rabbits only.
WHAT ARE THE SIGN SOF rhd 1
bleeding syndrome
100% mort
quite, pyrexic, inc RR
acute haemorrhage - no clotting factors made
what happens to kits infected <4wo with RHD1
they survive and get lifelong immunity
what nursing strategy might save a rabbit with myxomatosis
keep it warm! myxi is nastier when cold
what is the usual causes of death for rabbits with myxi
2ry bacterial infection (eg pasteruella)
what type of virus is myxi
pox
what type of virus is RHD
calici
how is myxi spread
insect vectors
direct contact
how is RHD spread
direct
insect vectors
lorries (RHD1)
rabbit show (RHD 2)
why and when should you neuter female rabbits
6mo
most will get a uterine adenocarcinoma by 3yo
stop pseudopregnancy
stops nasty-doe
when shoul dyou neuter male bunny
4mo+
should you routijely worm rabbits
no
there are 11 spp of coccidian for rabbits; 1 is fatal - which>?
e. stiedae
- -> hepatic coccidiosis (hepatomegaly, icterus, kg loss)
name a mite that causes facial crusting and might look like myxi
treponaema cuniculi (rabbit syphilis)
what ectoparasiticide with kill rabbits
FIPRONIL
how do you tx syphilis
penicillin
should you fast rabbits preop?
NO, because they cant V or regurg - but do remove pellets and greens 1 hr before and hay at 10mins before
how would you induce a rabbit for sx
injection! (they breath hold - gas is useless)
alfaxalone + midazolam + propofol (slowly to prev apnoea)
whats the most impt thing to check if decide to use a ‘v gel’ (laryngeal mask)
check mouth empty of food!
what rate of IVFT should be given
4ml/kg/hr of crystalloids - can increase this under GA if want
what impt changes to the anaesthetic protocol will you make for a compromised rabbit
- IVFT +- SC FT (use HA to inc aborption)
- emeraid
- motilin (metoclopramide + ranitidine)
- smaller doses, more drug types
what are the best analgesics for rabbits
buprenorphine & butorphenol both okay for DH patietns
NSAIDS + buprenorphine
CRI of ket, dexmedetom and morphine best
local - bupivacaine or lidocaine
name pro-kinetics
domperidone
metaclopromide
ranitidine
cisapride
name some diff methods of haemostasis
electro and radio cautery
ligatures
haemoclips
CATGUT (AND OTHERS) CAUSES SUTURE REACTION (adhesion and caseous inflam) IN RABBITS, instead use:
verapamil
- has a Ca++ blocker in it – prev adhesions
what is unusaly about the rabbit uterus
2x horns (normal)
no uterine body
2 x cervices!
also really fatty - bloooddd
why do you lavage a rabbit OVH
reuce adhesions
in a rabbit OVH do you remove cervices or like in dogs - doesn’t really matter
remove them - or will get adenocarcinoma
close or open rabbit castrates?
Closed – open inguinal rings!
what pathogens are often responsible for abscess formation
pasteurella staph proteus e coli f necrophorum corynebacterium pyogenes klebsiella strep
if you cant completely remove abscess - what do you do?
use gentamycin, amikacin, cefazoin IV or IM etc NOT ORAL
