Handling
the Avian Emergency:
Do's and Don'ts |
|
The avian practitioner
will be presented with three classes of
birds: the well-bird, the obviously sick
bird, and the bird harboring a sub-clinical
infection. The first two classes of birds
are very straightforward to deal with, but
it is the sub-clinically ill bird that is
most problematic for most avian practitioners.
Birds are masters at hiding signs of illness
as a protective mechanism. A sick bird will
attract predators to the flock, so a bird
will hide that it is ill for as long as
possible. A sick bird will usually be pushed
out of the flock when it can no longer keep
up with it. So, the ill bird will act as
normal as it possibly can for as long as
it can. This means that the bird that is
presented to you for clinical illness has
been sick for quite some time. Inexperienced
or unknowledgeable owners are likely to
miss the subtle signs of illness, such as
decreased vocalization, change in volume,
character or consistency of droppings, change
in appetite, weight loss or decreased activity
level.
DO educate your
staff about what to tell bird owners
prior to the bird coming in to your
office
Instruct your staff to make sure to
emphasize to bird owners that all
birds coming in to your practice MUST
be contained in a cage or carrier,
for the safety of the birds. A bird
on a human hand or shoulder of an
owner is at risk, because if it is
frightened, it may bite the owner,
and your clinic may be responsible.
If it is startled and jumps off the
shoulder, it may be attacked by a
dog or cat, resulting in the death
of the bird. Your clinic may be responsible
if this occurs, as well. If the bird
is flighted, it could end up flying
out an open door, and your clinic
could be responsible if the bird is
lost.
Are you beginning to see a trend here?
Owners should be instructed to bring
small birds in their cage, which has
not been cleaned, so that the vet
can evaluate the droppings. Large
birds may be brought in a carrier.
Ask the owners to bring in papers
from the bottom of the cage, if possible.

If the bird is very ill, on the bottom of
the cage, instruct the owner to bring the
bird in a dark, warm box instead of its cage.
An easy way to keep an ill bird warm during
transport is by having the owner fill a few
jars with hot water, then wrap them in towels,
and placing them in the box with the bird.
In place of jars, ziplock baggies, latex gloves
or hot water bottles can also be used.
The receptionist should also instruct the
owner to bring in any medications, supplements
or alternative medicine treatments that
he or she has been giving. It must be stressed
that this is very important, and the owner
should not be embarrassed if they sought
to use over-the-counter or alternative treatments
prior to seeking professional help.
DO see a sick bird as soon as possible
It is very important to teach your staff
about the differences between avian medicine
and dog and cat medicine. If an owner calls
about a sick bird, it is vital that the
bird be seen as soon as possible, even if
there are no scheduled openings in the appointment
book. I can't tell you the number of letters
I have read that were written to me at Bird
Talk magazine by very unhappy and inconsolable
bird owners who were told by the staff at
a clinic that their sick bird couldn't be
seen for several days, and the bird died
before the scheduled appointment! Remember,
a sick bird that has "crashed"
and is showing clinical signs has been ill
for quite some time, so any delay in providing
diagnosis and treatment may result in the
death of the bird! If a sick bird needs
to come in and you have no openings, suggest
that the owner drop off the bird. Make sure
that the staff gets a thorough history and
lets you know when the bird comes in, so
that you may take a few minutes to evaluate
the bird. Most sick birds require supplemental
heat, which is easy to provide with an incubator,
aquabrooder or heating pad. If the bird
appears critical, provide the bird with
heat and supplemental oxygen before you
attempt to do anything else to it. But,
please don't allow your staff to put off
a bird owner who feels that their bird is
ill. You may occasionally make room for
a bird that could have waited, but more
often than not, you will make the correct
decision by seeing the bird immediately.
DON'T handle a sick bird until a thorough
history and visual evaluation have been
performed
Any bird presented for a check up or even
grooming should not be handled until a thorough
history has been taken by the veterinarian.
While taking the history and after, observe
the bird in the cage or carrier. A bird
can be emaciated and weak, yet when it fluffs
out its feathers, it may look normal. By
carefully observing the bird prior to catching
it up for examination, you can be prepared
and know what to expect. Nothing is worse
than catching up a bird for routine grooming
and having it expire in your hands because
it was on the threshold of death. If the
bird looks bad, you can warn the owner about
the possibility that the stress of handling
may be enough to precipitate a crisis. This
way, if the bird does "crash"
in your hands, the owner will be better
prepared. Have oxygen ready, warmed lactated
ringers in a syringe, perhaps a syringe
of warm hand-feeding formula and a stainless
steel feeding tube, and any other equipment
or medications that you feel might be necessary.
DO assess the avian
patient's condition every moment during
the time it is being handled
This means that while you are examining
the bird and procuring the tests, your technician
is focusing all of his or her attention
on how the bird is handling the stress.
It doesn't help if you successfully draw
enough blood for a CBC and chem panel, but
the patient died two minutes ago! Actually,
you both must remain focused on the bird
at all times while it is in your hands.
This means that this is NOT the time to
discuss treatment options or to answer the
owner's questions about diet. All discussions
should take place after the bird is safely
back in its cage.
At the first signs of distress, the procedure
should cease, and the bird should be immediately
placed back in its cage, released to the
owner or placed in a bird intensive care
unit.
In cases where the bird is very ill, it
may be most important to stabilize the bird
first, and procure tests later. With a critically
ill bird, tests may need to be performed
in stages, or sometimes, they must be forgone,
so that all efforts are directed towards
support care.
DON'T forget your sound
medical background when dealing with the
avian emergency
Remember your medical skills when working
on a critical, injured or traumatized bird.
The same medical skills apply, with some
exceptions. You already know the basics
of emergency medicine, so let's go over
the differences.
Remember that birds have air sacs, and if
there is serious damage to the beak, oropharynx
or glottis, and establishing an airway is
difficult, an air sac can be cannulated,
and the bird can safely and easily breathe
through the tube.
Birds may be treated for "shock"
although their physiological response to
injury does not result in shock as occurs
in mammals. We must always remember that
steroid use in birds has potentially more
serious and long-standing consequences than
its use in mammals does. One injection of
a steroid in a critical bird is worth the
risk, however, its use will increase the
chance that the bird may develop aspergillosis,
a serious fungal disease. Steroids have
limited benefit in avian species, and topical
preparations are also dangerous.
Birds also have some pneumatized bones,
and a fracture may result in extensive SQ
emphysema. This is often puzzling to the
beginning avian vet, who may suspect rib
fractures. However, SQ emphysema is a common
sequela to a fractured pneumatized bone
and will usually spontaneously resolve with
24 hours.
Many ill birds are dehydrated. Fluids may
be given SQ (over the back of the neck,
where there is lots of loose skin, just
beware of the jugular veins), intraosseously
or intravenously. Hydrating a critical bird
is very important.
Many sick birds also require supplemental
heat, as they are not thermoregulating properly.
Keeping a sick bird in a cage with a controlled
temperature and humidity is very important.
Birds will do well in an incubator set at
between 87-92 degrees F. Humidity should
be over 75%.
Sick baby birds often become ill from being
kept at too low of a temperature. When this
happens, the GI tract slows down dramatically.
Therefore, giving any medications orally
is usually not a great idea, as absorption
will be erratic and slower than normal.
Parenteral antibiotics and therapeutics
are a better choice.
When bandaging or splinting a bird, make
sure that the sternum moves freely. Birds
breathe like a bellows, in and out, not
up and down, as mammals do. If the sternum's
movement is restricted, the bird may asphyxiate.
DO plan to clip the wings of hospitalized
birds
If a very sick bird is flighted, request
permission to quickly trim the wings. If
a sick bird escapes and can fly, much metabolic
energy may be spent by the bird. Also, smaller
birds may fly from perch to perch, becoming
more stressed than necessary, when they
must be captured several times per day for
treatment. Clipping the wings prevents these
problems. If the owner does not wish the
bird to be clipped, you can wrap a rubber
band around the last four or five primary
remiges on each wing to temporarily render
a bird flightless.
DO minimize stress in sick birds
Keep critical birds in a stress-free environment.
Don't put them in Premier Cages
where they can see their reflection. Keep
them in a warm, quiet, dark environment.
Don't keep a sick bird in a cage on the
clinic floor. Birds are most comfortable
up high, so take that into consideration
when deciding where to put birdcages.
DON'T forget to weigh hospitalized birds
daily
Monitoring a bird's weight daily is very
important in assessing how your treatment
plan is working. Make sure that the bird
is weighed every morning prior to being
tube fed and medicated, and that the weight
(in grams) is recorded in the chart.
DO learn how to perform a complete physical
exam on a bird quickly and efficiently,
using magnification
A physical exam may be performed on a bird
just as it can be in a mammal. Make sure
to record the weight. Assess the choanal
slit and choanal papillae, as this area
is often the best area to visualize to determine
the overall health of a bird. Perform the
physical exam by organ system or from top
to bottom, methodically, however you prefer.
Make sure to evert the cloacal mucosa, as
this area also provides good diagnostic
information.
DO maintain total hemostasis when working
on a bird
Although it is not true that a bird will
die from losing a few drops of blood, it
is very important to minimize any bleeding.
If a bird is bleeding badly, it is vital
to stop the bleeding as quickly as possible.
If a bird won't stop bleeding after venipuncture,
a pressure bandage may be applied for 20
minutes or so, until clotting has occurred.
Clotisol, a liquid clotting agent, is safe
and effective to use in birds. Use of a
radiosurgical unit (and NOT an electrocautery
unit) is very helpful in stopping bleeding.
Avian emergency medicine requires the same
fundamentals as mammalian emergency medicine,
however, there are some major differences
that must be understood, as well. Once the
differences are learned, the practice of
avian medicine will prove much easier. A
good understanding of avian anatomy, physiology
and pharmacology is essential to the avian
practitioner.
