A wound is a break in the continuity of the skin. Wounds can range from shallow, partial thickness wounds that involve only the superficial layers to full thickness wounds that reveal deeper tissues, perhaps muscle, tendon, ligament or bone. The wound location and the tissues involved are more critical than the overall appearance of the wound. The vet will usually need to see the wound to advise on the best course of treatment and possible complications. Even tiny wounds close to a joint on the limb can be very serious. Despite their size the vet may take these small wounds very seriously and may undertake further investigation. It is essential that your horse is properly vaccinated against tetanus.
The vet should be consulted about every wound. This is especially important if:-
These are wounds at high risk of complication or may only be resolved by surgery.
In order for the vet to give the best advice on the treatment of a wound it is important to be able to describe the wound accurately, its nature, extent and location can make a diffrence to the treatment procedure.
Wounds that are bleeding heavily involve important blood vessels and wounds that bleed in a pulsatile manner involve arterial damage. Both of these wounds need immediate veterinary attention.
Bleeding can be controlled temporarily by the application of a pressure bandage. A sterile absorbent dressing is applied directly to the wound with a pad of absorbent cotton dressing and this is bandaged firmly in place. The vet should be called immediately.
There are many reasons that wound healing can be prolonged or may fail. The specific factors that might delay healing in a particular wound will be addressed by the vet in a way that is practical for you and your horse and you can discuss any concerns that you might have.
Wound cleansing - wounds cleansed within 4-6 hours of wounding are at a lower risk of complication and infection. Once bleeding has stopped the wound should be cleansed using plenty of clean water or warm saline made up with 2 teaspoons of salt to 1 litre of cooled boiled water. Flushing the wound thoroughly with a hosepipe is acceptable as an initial flushing. Chemicals, oniments and pastes should not be applied without veterinary guidance.
Dressing changes - applying a bandage is a skilled process and the vet will advise you on how to apply a dressing and bandage properly. The dressing the vet advises is likely to be matched to the type of wound your horse has. Always discuss alternative dressings with the vet first.
Minimise movement at the site of the wound - this can slow the process of healing and so special bandages may be required that limit movement. Box rest may also be required.
Seek veterinary advice - if you have any concern about a wound always consult the vet. Advice over the phone may be all that is required.
Personal safety is paramount - only attempt to change dressings and cleanse wounds if it is safe to do so. Frightened or lively horses may need to be sedated to achieve thorough cleansing and a dressing change.
Many wounds can be closed easily using sutures or staples and it may be possible for the vet to do this where your horse is kept. Sometimes closing a wound early can be detrimental rather than helpful so do not be surprised if the vet doesn't do this. The vet may need to insert a drain in to the wound to help release fluid during healing. The horse may require an anaesthetic or have to be admitted to hospital for specialist care.
'Proud flesh' is a well recognised complication of wound healing in horses, especially for leg wounds. The management of this often requires surgical intervention and may involve skin grafting to achieve the best results. Grafts or reconstruction wold usually be performed in a hospital situation. These techniques are used to reduce healing time and improve the cosmetic appearance.
