Applying Pressure Bandages
When a
horse sustains a serious leg injury, it is sometimes
necessary to stabilize the limb and control bleeding and
swelling until your veterinarian arrives. A pressure bandage
is an effective first aid tool that can be used to
accomplish this task.
Keep in mind, however, that any leg injury serious enough to
require a pressure bandage is serious enough to require
immediate professional attention. You should also
recognize that pressure bandages can be potentially harmful
if not applied correctly. If you know how to correctly apply
a pressure bandage, you can come to the horse's aid without
causing further damage.
Purpose
The
purpose of the pressure bandage is to protect the injured
area and control bleeding without constricting normal
circulation.
Pressure bandages are used to:
-
Control bleeding
-
Minimize swelling
-
Provide support for an injured limb
-
Absorb fluids (exudate) from a wound
-
Protect a wound from contamination or additional trauma
Wound
Care
The
severity or type of injury will determine the best course of
action. If there is an open wound with profuse bleeding - or
it appears that a major blood vessel has been cut (blood
appears to spurt not trickle) - your primary concern will be
to stop the bleeding. You will probably need to forego
cleaning and apply pressure to the wound immediately.
If bleeding is light to moderate, it may be best to cleanse
the wound using cool running water from a hose prior to
bandaging. Avoid prolonged hosing (not more than 10-12
minutes) as it may increase swelling. A commercially
available sterile saline solution or a
solution of 2 tablespoons plain table salt to one gallon of
water can also be used.
Ideally the saline solution should be applied with pressure
to loosen and flush dirt and debris from the wound. Avoid
scrubbing as this may further damage tissue, increase
bleeding, or drive dirt and debris deeper into the wound.
An antibacterial soap can be used to wash the surrounding
area, but care should be taken to avoid getting soap into
the wound itself.
Stress or traumatic injuries, such as bowed tendons, will
benefit from being hosed or iced for 5-10 minutes prior to
applying a pressure bandage.
Pressure
Bandaging Materials
If an
open wound is involved, gauze pads, a clean cotton
washcloth, sanitary pads or other sterile non-stick dressing
should be placed over the wound.
Do not use sheet or roll cotton directly against a wound.
While cotton is absorbent and provides excellent padding,
the fibers will stick to the tissue and contaminate the
wound.
Once the wound is covered, you should use roll cotton, sheet
cotton or leg quilts to pad the bandage.
Adequate padding is essential to distribute pressure evenly
around the limb. Padding should be at least 2 inches thick.
This will allow you to apply sufficient tension to the
support bandage to control bleeding and swelling. The extra
padding will also absorb drainage
Generally, the longer a bandage is to remain in place, the
greater the amount of padding needed.
Track or polo wraps, cotton flannels, roll gauze,
3MTM™, Vetrap™, Bandaging Tape, Elastikon™, Ace™ bandages or
even duct tape can be used for the external (pressure)
layer.
Bandaging material should be at least 2-3 inches wide. This
will help prevent a tourniquet effect and allow for
sufficient overlap of the layers.
Using stretch fabric makes bandaging easier, allows for
movement, and is less apt to restrict circulation as long as
it is not pulled too tightly.
General
Guidelines
If you
have never bandaged a horse's legs, ask your veterinarian or
an experienced equine professional to demonstrate the proper
techniques. Practice under his or her supervision before
doing it on your own.
Follow these basic guidelines:
-
If blood loss does not appear excessive, clean the
wound, removing as much dirt, hair and debris as
possible prior to bandaging.
-
Cover open wounds with sterile, non-stick gauze or
dressing. Do not apply sprays or chemicals to wounds
that may need to be repaired. Water-soluble ointments
can always be used; petroleum based ointments should not
be used in surgically repairable injuries.
-
Apply soft, absorbent padding, such as roll cotton, at
least 2 inches thick around the injured limb. Make sure
it lies flat and wrinkle-free against the skin.
-
To prevent slippage, begin the support bandage at the
foot, covering the heel bulb and coronary band (where
hoof meets hair) and work up the leg.
-
Extend the pressure bandage 4-6 inches above the injury
site. If the injury is in the lower leg, always bandage
to the knee or hock.
-
Wrap the leg front to back, outside to
inside(counterclockwise on left legs, clockwise on right
legs).
-
Spiral support fabric upward, overlapping each preceding
layer by 50 percent.
-
Use smooth, uniform tension on the bandage to compress
the padding without forming lumps pr ridges beneath the
bandage.
-
Apply sufficient pressure to control the bleeding,but do
not wrap so tightly that you cannot slip a pinky finger
inside the bandage.
-
Do not wrap too loosely as the pressure bandage will not
do its job.

Special Considerations
- A
pressure bandage should be left in place until the
veterinarian arrives.
-
·Point out the exact location of the injury so the
veterinarian can avoid disturbing it when removing the
bandage.
-
If blood soaks through the bandage, place a second
bandage over it as before. Do not remove it, as this
could disturb any blood clots that may be forming and
encourage more bleeding.
-
Monitor and evaluate the horse frequently. Remember,
pressure bandages can be dangerous. If swelling develops
above the bandage or lameness increases, check to see
that the bandage is not cutting off the circulation and
seek your veterinarian's advice.
-
Watch for other problems. If the horse loses its
appetite or there is an elevation in body temperature,
contact your veterinarian. If the bandage appears to be
too tight, cut through the support layers, - leave them
in place, and wrap the new bandage around the first one
more loosely.
-
Extreme emergencies include injuries that don't stop
bleeding within 15-20 minutes, lacerations that extend
into joints and tendons, and severe breakdowns or
injuries in which the horse is unable or unwilling to
walk. In any of these situations, get veterinary
assistance immediately.
