Q

How to control H&S risks?

A
  • Limit those at risk:
    – staff
    – volunteers
    – general public

    assessments and SOPs:
    – staff
    – volunteers
  • Provide suitable facilities,
    equipment and training:
    – gloves
    – gauntlets
    – graspers
    – cages
    – swan bags etc.
  • Vaccination where
    recommended (rabies, bTB).

Q

Triage definition:

A

‘The assignment of degrees of urgency to wounds or
illnesses to decide the order of treatment of a large
number of patients or casualties’
* ‘The process of determining the most important people
or things from amongst a large number that require
attention.’

19
Q

Most common usage of triage:

A

initial assessment of a casualty to
make a decision to treat or
euthanasia’

20
Q

Legalities regarding non-indigenous species (eg grey squirrels, muntjac deer):

A

require licenses to keep. Cannot legally be released

21
Q

Considerations for initial assessements of wildlife casualty:

A

From a distance, quite and safe environment, experienced person, ASAP.
Consider mentation, demeanor, movement, breathing, wing position.

22
Q

Examining head:

A
  • Eyes – ophthalmic examination
    especially in birds of prey
  • Ears and nares for discharge or
    bleeding
  • Jaw – fracture, dislocation
  • Oral cavity of birds - bleeding,
    white plaques (Trichomonosis),
    parasites (Syngamus trachea)
  • Beak - not soft, closes normally,
    normal length, no excess scaling,
    not unevenly worn
  • Take care regarding health and
    safety.
23
Q

Skin, feathers, coat and spines

A
  • Examine the whole of the outer
    body for evidence of wounds,
    bruising or bleeding
  • Wounds (e.g. from cat bites) may
    be very small on the outside but
    extensive inside the animal
  • Look for any abnormalities in the
    skin and coat or feathers
  • Notice any missing or damaged
    feathers, lack of pigmentation,
    stress (fret) marks
  • Look for ecto-parasites.
24
Q

Anus, cloaca, reproductive system

A
  • Look for excessive soiling around the
    anus or cloaca and anal abnormalities
    (e.g. prolapses)
  • Look for discharge from the vulva in
    female mammals
  • In birds check for a ‘brood patch’
  • In female mammals check the
    mammary glands for evidence of
    feeding young or other abnormalities
  • In male mammals check the prepuce
    for discharge or wounds and the
    scrotum for wounds
25
Q

What is a brood patch?

A

also known as an incubation patch, is a patch of featherless skin on the underside of birds during the nesting season.

26
Q

Limbs, feet, wings and tail

A
  • In birds consider the wing position
  • Check each wing separately, palpate
    and gently manipulate the joints
  • Look and feel down each leg, gently
    move the joints
  • Look at the feet and claws for
    evidence of sores, thickening, or
    abnormal wear
  • In water birds check the foot web
  • Look and feel down the tail in
    mammals with large tails. Check the
    tails of reptiles in a similar way.
27
Q

Body weight (clinical exam):

A
  • Weigh the casualty if you can either directly or using a
    pre-weighed box/cage and subtracting the known weight
  • Record the weight (g or Kg) on a record sheet
  • Weight can be compared to average weight charts for
    that species, but will vary with age, sex, health and
    season of the year
28
Q

Body temp considerations:

A
  • May be possible to take a rectal / cloacal temperature
    safely.
  • Remember body temperature varies with:
    – disease
    – environmental temperature (time of year)
    – stress
  • Can be useful for prognosis (e.g. in oiled birds)
29
Q

Badger body temp

A

36.0-38.0°C

30
Q

Fox body temp

A

35.9-40.4°C

31
Q

Otter body temp

A

37.8-40.0°C

32
Q

Deer body temp

A

38.6-39.3°C

33
Q

Hedgehog body temp

A

35.4-37.0°C

34
Q

Rabbit body temp

A

38.5-40.0°C

35
Q

Bird body temp

A

41.0-44.00°C

36
Q

Checking for identification:

A
  • Look for evidence of:
    – rings on birds and bats
    – tags or tattoos on birds and
    mammals
  • Scan with a microchip
    reader, microchips are
    usually:
    – mammals: between the
    scapulae
    – birds: pectoral muscle.
37
Q

First aid for wildlife casualty?

A
  • Fluid therapy
  • Analgesia
  • Stopping haemorrhage
  • Fracture support
  • Temperature
    maintenance
  • Nursing care
  • Accommodation
  • Food and water.
38
Q

Medical reasons for euthanasia

A
  • Behavioural abnormalities
  • Damage to jaw or beak
  • Loss of hearing
  • Blindness
  • Loss of an eye, or vision in an
    eye, where essential
  • Loss of a limb (or wing) or
    permanent loss of function
  • Fracture of a limb or wing
    involving or very close to a joint
  • Permanent feather damage or
    loss of waterproofing
  • Fracture of the pelvis resulting in
    narrowing of the pelvic canal
  • Loss of reproductive function.
39
Q

Accomodation in vet practice:

A
  • Not really ideal places for wildlife
  • Appropriate level of isolation
  • Appropriate place in the practice
