31
What are they key points to note on the physical exam of a patient with shock?

``` Bloods: • PCV • Total Proteins • Blood smear • Glucose +/- Urea Radiographs: • Specially on trauma cases • Always under sedation/GA • Only when patient stable ```
34
Describe ongoing rehabilitation of wildlife key points
- Limited contact with humans/other animals: • Biosecurity concerns • Stress • Changes in behaviour - Housing during treatment should meet the species requirements - Hospitalization area: ideally separated in avian, mammal and herp patients - Large outdoor enclosures
35
Describe release of wild animals
- Planning ahead release area: • Ideally same area where animal was found • Season and time of day - Pre-release general health-check and disease screening - Monitoring released animals
36
How can different wild animals be monitored following release?
* Birds – rings, wing marks, telemetry or GPS devices, data loggers, etc * Mammals – ID chip, telemetry colar * Reptiles – ID chip * Amphibians – not usually marked
37
When would orphaned bird need examination/treatment?
- Obvious trauma or lesions - Imminent risk of predation/injury - If still present on the same area after 12-24h
38
Describe the initial approach to orphaned birds?
- Provide supplemental heat - Once rewarmed provide fluids and supplemental feeding by crop tube - Reduce human contact to prevent imprinting and behaviour changes
39
Name the different traumas that birds may present with
``` Head trauma Wing fractures Leg fractures Lacerations and bite wounds Other less common trauma (luxation, spinal trauma, electrocussion) ```
40
What are signs to look out for in birds with head trauma?
- Altered mentation - Haemorrhage on oral cavity/ears - Hyphema (bleeding in the front (or anterior chamber) of your eye, between the cornea and the iris) - Anisocoria = unequal pupil size - Facial paralysis (check head feathers)
41
What is given to provide analgesia in birds?
Meloxicam
42
How are wing fractures managed?
- Immobilize wing as soon as possible - Different splinting techniques: • Coracoid/Humerus – figure of 8 bandage + body tape • Radius/ulna – figure of 8 bandage • Carpus/metacarpus – tape splint - Once stable, GA + radiographs - Ideally, orthopaedic surgery to restore normal wing function
43
How are leg fractures managed in wild birds?
- Immobilize leg as soon as possible - More difficult to stabilize than wing fractures Different splinting techniques: • Femur – difficult to stabilize hip joint, require surgery • Tibiotarsum – lateral splint with lightweight material • Tarso-metatarsum – lateral splint or tape splint (birds <150g) • Digits – cage rest (small birds), ball bandage or snowshoe splint. - Once stable, GA + radiographs - Ideally, orthopedic surgery for femoral and tibiotarsal fractures
44
What are the general principles of wound management?
- Consider sedation/GA for wound examination/ management - Flush with sterile Saline 0.9% - Remove any necrotic tissue - Cover wound with hydrocolloid gel, Manuka honey or Silver sulfadiazine creams - Wet-to-dry dressing or non-adhesive dressing applied - Most wounds are contaminated/infected – healing by 2nd intention, do not suture - Analgesia + Antibiotics (specially if bite wounds) – Amoxicillin + Clavulanic Acid
45
Which wild birds have an increased risk of lead poisoning?
Swans and waterfowl | Birds of prey
46
What are the sources of lead?
Gun pellets left in the environment/game
47
What are the clinical signs of lead poisoning?
- Variety of neurologic signs - Pale mucus membranes - Haemoglobinuria
48
How is lead poisoning diagnosed and treated?
- X-rays: look for metallic densities on GI tract - Lead blood levels: significant if > 0.02ppm Treatment (options): - Calcium EDTA - Penicillamine - Supportive care
49
What is the cause of botulism in wild birds?
Ingestion of toxin type C produced by Clostridium botulinum
50
What are the clinical signs of botulism?
- Progressive flaccid paralysis (+ neck muscles) - Associated with more or less high mortality - Outbreaks can last several weeks
51
How is botulism treated?
- Fluids - Activated charcoal - Supportive care - Anti-type C toxoid serum (not cost-effective) - Severe cases should euthanized
52
Describe treatment for oiled birds
1. Supportive care (fluids, activated charcoal, bismuth subsalicylate) 2. Provide supplemental heat 3. Clean mucosas and eyes first with sterile Saline 0.9% 4. Start prophylactic antifungals 5. Remove oil from plumage (water 40° C + Fairy®) 6. Remove detergent from plumage – soft warm water 7. Dry plumage 8. Restore feather structure
53
What are the common presentations for hedgehog casualties?
* Trauma (eg RTA, bite wounds) – nasal trauma carries poor prognosis * Complicated wounds – necrotic tissue, infection, flystrike * Emaciation * Neonates * Respiratory disease – incl. hedgehog lungworm * Limb entrapment * SC emphysema * Accidental poisoning
54
How must bats always be handled?
Always handle bats with latex + garden gloves due to risk of zoonosis
55
What are common problems in bats?
``` Trauma: • Cat bites • Wing tears and lacerations • Fractures - Entanglement - Contamination (glue, oil) + chemical burns - Intraspecific bites (during breeding season) + facial abscesses - Orphan pups ```
56
What are common problems in foxes
- Trauma (wounds, fractures) - Mange: Sarcoptes scabiei, potentially zoonotic! - Dental trauma (during capture/captivity) - Orphan pups
57
Describe the pathophysiology of capture myopathy
Intense muscle activity -> Tissue acidosis (Lactic acid) -> Metabolic acidosis -> Inflammation and muscle necrosis (incl. myocardium) -> Acute renal failure
58
What are the risk factors for capture myopathy?
- Acute stress - Capture/restraining - High temperatures
59
What are the clinical signs of capture myopathy?
- Paresis - Paralysis - Ataxia - Sudden death
60
How is capture myopathy treated?
- Fluids - Midazolam - Vitamin E + Selenium? - NSAIDs? - Even aggressive treatment is frequently unrewarding - Consider euthanasia if not responding in 24h
