FIRST AID FOR WOUNDS
Horses and ponies often
receive cuts and other wounds particularly on their face
and legs. Many require just simple first aid measures, while
others require the attention of your veterinary surgeon.
Simple first aid measures can help reduce the risk of infection
or further damage.
Basic First Aid Kit
Your first aid kit
should contain the following items;
Sterile non-stick dressings
(10 x 10 cm or 10 x 20 cm sizes)
Cotton wool or Gamgee roll
Bandaging materials including self adhesive sticky and non-sticky
bandages
Spare clean stable bandage
Small bottle of disinfectant, such as Betadine, Hibiscrub,
Savlon or Dettol etc.
Scissors
Wound poultice dressing
Antibiotic wound spray and/or wound powder
What should I do first?
If your horse has sustained
a cut or wound the most important thing to do is to stop
the bleeding. This can be done by applying direct pressure
to the wound using a clean piece of Gamgee roll or cotton
wool, either held or bandaged in place until the bleeding
has stopped or your veterinary surgeon has arrived. Tourniquets
are less favoured now because of the risk of causing thromboses
(blood clots) in the veins and arteries. If there is foreign
material protruding from the wound, pressure should be applied
immediately above and around the wound. This can be done
by hand or where possible by creating a ring of bandaging
material so that pressure can be applied to the surrounding
area without applying any more pressure to the foreign body.
If this is small and can safely be removed, it is best removed.
Always tell your veterinary surgeon if you have removed
a foreign body, and keep it for his examination, as he will
wish to make sure that no more are left more deeply in the
wound.
If an artery or vein
has been cut it may take 20 minutes to half an hour for
bleeding to stop. In some cases of arterial bleeding, this
cannot be stopped until the artery has been clamped or tied
off by a veterinary surgeon and in such cases it is important
to continue to apply pressure till he or she arrives. Once
bleeding has stopped or if the wound has not bled excessively
it should be cleaned to reduce the risk of infection. Be
gentle and careful not to re-start the bleeding. Liberal
dowsing with water, using a hose, is effective at flushing
off dirt and debris and helping to minimise swelling and
inflammation. Cold water also helps to stem bleeding.
Minor wounds can be
cleansed using a dilute solution of disinfectant. If the
wound is in an amenable area, a non-stick dressing should
be applied, covered with a piece of cotton wool or Gamgee
roll and held in place by a self adhesive bandage. If the
wound is large or deep or there has been extensive bleeding
your veterinary surgeon should be called. While waiting
for your veterinary surgeon the wound should be left covered
where possible. Wounds on the upper limbs, body and head,
not amenable to bandaging, should just be cleaned and left
open or continually cold-hosed. Do not apply wound powder
or ointment just in case the wound needs stitching, unless
your veterinary surgeon is going to be delayed, when it
is helpful to cover the wound with anti-bacterial ointment
such as Betadine or Savlon just to keep the tissues soft
and help prevent them from drying out. Some improvisation
may be called for in the presence of large skin flaps such
as those which may occur on the belly or upper limb. With
these wounds it may be necessary to try to use clean towels
or sheets held in place with bandaging materials just to
try to prevent further damage occurring to the skin and
underlying tissues.
Which types of wounds
need stitching?
Wounds which penetrate
the full thickness of the skin or deeper, wounds on the
nostrils, lips and eyelids, wounds where a flap of skin
has been created and wounds where underlying tissues have
been exposed should always been seen by a veterinary surgeon
as in most instances they will require suturing. Small wounds
however, even if full thickness can very often be left unsutured.
Most heal uneventfully. If your horse has a wound that you
think may require suturing it is important to call your
veterinary surgeon as soon as possible. Wounds sutured within
4 hours of occurrence tend to heal much more successfully
that those that are repaired later, after the tissues have
started to dry out. When sutured later, wounds may have
already developed a considerable amount of swelling are
therefore less amenable to suturing and are more susceptible
to the development of complications.
Wounds over joints,
tendon sheaths and penetrating body cavities
Wounds involving joints
and tendon sheaths are always potentially life-threatening
as infection in these structures can be extremely difficult
to resolve even if undertaken very quickly. Inflammatory
responses can result in joint surface or sheath membrane
damage and, with associated infections, can cause long term
or permanent incapacity. If unsure whether a wound has penetrated
a joint or sheath, your veterinary surgeon may wish to take
a sample of joint or sheath fluid (joint or sheath tap)
to test the cell count and the appearance of the cell types
(cytopathology) to determine if the joint or sheath will
require to be flushed with large quantities of sterile saline
solution and antibiotics to remove the associated infection,
its toxins and the inflammatory proteins. The sooner this
is done following injury the better are the chances for
a successful recovery. Your veterinary surgeon may wish
to take x-ray pictures of the area to make sure that there
are no fractures and to look for demonstrable foreign bodies.
Similarly, penetrating
wounds into the chest and abdomen may cause immediate death
or serious life-threatening complications. Wounds into the
chest affect a horse’s ability to breath and will
result in the development of pleuropneumonia. Penetrating
wounds into the abdominal cavity will result in the development
of peritonitis and may cause damage to any of the internal
organs. These cases, if resolvable, will need intensive
treatment. Your veterinary surgeon should be called immediately,
stressing the emergency nature of the injury.
Tetanus Protection
Any wound can result
in contamination with environmental bacteria, which may
include Clostridium tetani, and your horse developing tetanus.
This is a particular risk if the injury has been a puncture
wound and the skin surface has closed over relatively quickly,
resulting in the air-less conditions in which these bacteria
like to grow and produce their toxins. Every horse should
be fully and regularly vaccinated against tetanus, to reduce
the risk of this disease and avoid the worry that minor
wounds may result in such unnecessary complications. Tetanus
vaccine is initially administered on two occasions a month
apart. A third vaccine is given at 12 months and booster
vaccinations are given every 24 months. In most cases this
vaccination regime can be combined with that for influenza
and there are no excuses for not taking advantage of this
life-saving vaccine.
