Hospitalisation and Nursing of Rabbits, Rodents and Ferrets Flashcards
what are the main musculoskeletal features of rabbits?
skeleton is very light but have hugely powerful hind limbs which means they can damage themselves
what are the main respiratory tract features of rabbits?
obligate nasal breather
larynx is hard to visualise so are difficult to intubate
small lungs relative to size
what are the main digestive features of rabbits?
hypsodont aradicular teeth
large, thin walled stomach
small and large intestine designed to digest grass
GI tract makes up large proportion of body weight
coprophagia
are rabbits able to vomit?
no
does the stomach fully empty in rabbits?
stomach is never fully empty and contains hair balls which may be problematic if animal becomes dehydrated
what are the main urogenital features of rabbits?
males have open inguinal ring which should be closed on castration
females have 2 cervices and large thin walled vagina
lots of fat in uterine ligament
why are rabbit spays difficult?
lots of fat in uterine ligament
what are the main eye features of rabbits?
prominent, forward facing eyes
have large venous plexus at medial canthus
how may increases pressure in the vena cava be seen in rabbits?
eye will protrude due to large venous plexus at medial canthus
when should the rabbit be first assessed?
in the cage alone before it is handled
what must be assessed about a rabbit?
posture HR RR temperature droppings weight
is HR easy to monitor in rabbits?
no - very rapid
describe the RR of rabbits
fast and shallow
what is the correct temperature range for rabbits?
38.3-39.4 degrees
what should rabbit droppings look like?
round, plump and produced regularly
what is one of the most crucial things to monitor in the hospitalised rabbit?
droppings
what can be done to make hospitalisation as good as possible for rabbits?
secure non-slip floor correct temperature to avoid heat stress no predators offer water from bottle and bowl bring food from home companion should be brought as well wherever possible out of cage exercise to increase gut motility
what veins can be used for blood sampling in rabbits?
lateral saphenous
marginal ear vein
cephalic
jugular
how should the rabbit be restrained for lateral saphenous blood sampling?
lateral recumbancy
what is the marginal ear vein useful for?
small samples
IV catheterisation
what is the jugular vein useful for in rabbits?
large volumes e.g. blood transfusion
what level of restraint is required for jugular vein sampling?
very good conscious restraint or sedate to reduce risk of jugular laceration
what volume of blood can be safely taken from rabbits?
max 1ml/100g but less is better
via what routes can rabbits be medicated?
oral SC IM IV topical shampoo cream pesticides (spot on)
what muscle is most commonly used for IM injections in rabbits?
quadriceps
why is it vital that rabbits have pain controlled?
improve QOL and encourage eating to avoid gut stasis
why is pain so difficult to assess in rabbits?
natural response is to hide signs due to prey status
what signs of pain may a rabbit show?
quieter than normal teeth grinding (severe pain)
what can be used to assess rabbit pain levels?
rabbit grimace scale
what analgesia may be given to rabbits?
NSAIDS - e.g. meloxicam
Opioids - e.g. buprenorphine or methadone
when should rabbits not receive NSAIDs?
if dehydrated
if in doubt about a rabbits pain status what should you do?
give analgesia
are buster collars tolerated by rabbits?
not that well - can be stressful and prevent coprophagia
when may it be necessary to put a buster collar on a rabbit?
to prevent chewing through drip lines and dressings although some will still chew through drip lines with one on!
what is the prefurrable type of buster collar for rabbits?
soft
what is the fluid maintenance calculation for rabbits?
100ml/kg every 24 hours
why is rabbits fluid maintenance rate high than dogs and cats?
due to higher metabolism
through what routes can fluid therapy be provided to rabbits?
oral
SC
IV
what is the disadvantage of oral fluid therapy?
difficult to get volume in to replace deficits
what volume of fluid can be given subcutaneously?
~100 mls
what veins may be used in the rabbit for IVFT?
marginal ear
cephalic
lateral saphenous in an emergency as hard to secure
how may IVFT be given to rabbits?
drip
bolus - no fluid line so may be better tolerated by rabbit
what fluids are most commonly used for IVFT in rabbits?
crystalloids (0.9 NaCl or Hartmann’s)
what may colloids be used for in rabbits?
raising BP or in the case of blood loss
are blood transfusions used in rabbits?
yes - not much known about blood types so matching is recommended
what test can be used to match blood in rabbits before transfusion?
slide agglutination cross match
how may rabbits be fed if unwilling to eat on their own?
syringe feeding
what size syringe is needed to syringe feed rabbits?
1ml
describe how to syringe feed rabbits
1ml at a time so rabbit can eat without spitting anything out
small tip of syringe into side of mouth
what type of food should be syringe fed?
finely ground grass based
what type of fibre must be supplied to rabbits?
long chain fibre
what can be used to get long chain fibre into a rabbit’s diet?
strong flavored herbs or dandilions
what parasites are rabbits affected by?
mites
fleas
coccidia
worms
how can rabbit mites be diagnosed?
hair plucking
what mites are commonly found on rabbits?
Cheyletiella paristivorax
Listrophrus gibbus - fur mite
what are the signs of mites found on rabbits?
hair loss and irritation
how are mites on rabbits treated?
ivermectin
what sort of fleas do rabbits often get?
rabbit fleas rare in domesticated rabbits
most often cat fleas
what is caused by Coccidia in rabbits?
GI upset
how is Coccidia diagnosed in rabbits?
faecal floatation or wet prep
are rabbits routinely wormed?
no as worms are rarely of clinical significance
what is the main GI issue found in rabbits?
gastrointestinal stasis
is gut stasis in rabbits an emergency?
yes
what is gut stasis?
reduced or stopped intestinal motility so food doesn’t pass through
what are the presenting sings of gut stasis?
anorexia
absence of droppings
abdominal pain (quiet, hunched up, bruxism)
what are the main causes of gut stasis in rabbits?
pain
stress
inappropriate diet
other concurrent disease
how is gut stasis treated?
analgesia fluids prokinetics syringe feeding - crucial look for underlying cause
what prokinetic drug is used for rabbits?
metaclopromide - although not ideal
what level of substance in the blood is useful for assessing pain levels?
glucose
what does a glucose reading of <5 indicate in rabbits?
low due to pathology or inappetance
what does a glucose reading of 5-10 indicate in rabbits?
