Wound treatment in dogs and cats

Wounds are common injuries in dogs and cats that require appropriate treatment to prevent infection and promote healing.

Before we dive into the details of wound treatment, it is important to consider the anatomical and physiological differences between dogs and cats. For example, dogs have thicker skin than cats, which can affect the choice of dressing materials. Cats, on the other hand, tend to have more sensitive skin that requires special attention.

The first stage of wound treatment is to thoroughly clean and disinfect the wound. This is crucial to remove possible germs and minimise the risk of infection. Recommended solutions for cleaning are physiological saline solution or sterile Ringer's solution. The choice of disinfectant should be made carefully to avoid irritation or allergic reactions.

The next step is wound closure, which can vary depending on the type and severity of the injury. Small superficial wounds can usually be left open to promote healing through granulation. For deeper wounds, sutures, staples or skin adhesives may be required. The choice of the appropriate closure method should be made by the vet, taking into account the individual needs of the animal.

In recent years, modern approaches to wound treatment have developed, including the use of hydroactive dressings, for example, which retain moisture and promote wound healing. Stem cell therapies and growth factors, which can promote tissue regeneration, are also very promising. However, these approaches are still the subject of intensive research and are not routinely used.

Types of wounds and causes in dogs and cats

Wounds in dogs and cats can be categorised into different types depending on their cause and depth. The most common types of wounds include

• Cuts: These are caused by sharp objects such as knives or broken glass. They can cause deep or superficial cuts.
• Abrasions: Abrasions occur when the skin is abraded. They can result from falls, rubbing on rough ground or fights with other animals.
• Bite wounds: Bite wounds often come from fights with other animals. They can be deep and infectious as they can introduce bacteria into the tissue.
• Puncture wounds: Puncture wounds are caused by sharp objects such as nails or thorns. They can cause deep tissue damage.
• Lacerations: These wounds are often caused by tearing of the skin, as can be the case in accidents or fights.

The causes of wounds in dogs and cats can be varied and often depend on the activities of the animal and its environment:

• Accidents: Accidents such as falls, collisions with vehicles or getting caught in fences can lead to various types of wounds.
• Fights: Fights with other animals, whether within the same species or with strangers, can cause bite and scratch injuries.
• Foreign objects: foreign objects such as thorns, broken glass or spikes can cause puncture wounds or cuts.
• Self-injury: Some animals lick, scratch or bite themselves, which can lead to wounds.
• Medical procedures: Wounds can also be caused by surgical procedures, such as neutering or tooth extractions.
• Skin diseases: Certain skin conditions such as hot spots or allergic reactions can cause animals to scratch more, resulting in sores.
• Weathering: Extreme weather, sunlight or extreme temperatures can damage the skin and cause abrasions.

Overall, knowledge of the different types of wounds and their causes is important in order to take appropriate measures for prevention, treatment and healing. It is advisable to always monitor wounds in pets carefully and seek veterinary advice if in doubt.

Risks of wounds that are not treated immediately or properly

Wounds that are not treated promptly or correctly can have serious consequences for the health and well-being of dogs and cats. Neglecting wound care can lead to the following risks:

• Infections: Open wounds provide an entry point for bacteria, viruses and other microorganisms. Untreated infections can spread quickly and lead to serious systemic diseases that threaten the life of the animal.
• Delayed healing: Inadequate wound care can prolong the natural healing time. Not only can this cause distress to the animal, it can also increase the risk of complications and increase the likelihood of scarring.
• Chronic wounds: Wounds that are not treated appropriately can become chronic. Chronic wounds are difficult to treat and can lead to constant pain, inflammation and a severe impact on the pet's quality of life.
• Abscesses: Untreated wounds, especially bite wounds, can lead to the formation of abscesses. Abscesses are pus-filled cavities that often have to be opened and cleaned surgically.
• Tissue necrosis: Poorly treated wounds can lead to tissue necrosis, in which the surrounding tissue can die. This can enlarge the wound, hinder healing and increase the risk of infection spreading.
• Scarring: Untreated or poorly treated wounds have an increased risk of unsightly scarring. This can not only be aesthetically disturbing, but can also impair the function of joints and muscles.
• Sepsis: A severe infection that spreads from the wound throughout the body can lead to a life-threatening condition called sepsis. Sepsis can lead to organ failure, circulatory problems and, in the worst cases, death.
• Behavioural changes: Untreated pain and discomfort due to wound injuries can change the animal's behaviour. Aggressiveness, fear or withdrawal can occur, which can affect the relationship between the animal and owner.

Overall, consideration of the risks of wounds that are not treated immediately or properly emphasises the need for appropriate and timely wound care. Veterinary professionals play a crucial role in the assessment, diagnosis and treatment of wounds to ensure the health and welfare of animals.

First aid for wound injuries in dogs and cats

In the event of a wound injury in a dog or cat, it is important to assess the situation calmly. Make sure that you do not endanger yourself or the animal. Before approaching the injury, calm the animal to minimise stress. Examine the wound carefully without causing unnecessary stress to the animal.

In the case of bleeding wounds, rapid haemostasis is necessary to prevent excessive blood loss. Use sterile gauze bandages or clean cloths to apply pressure to the wound. Elevate the affected area to reduce blood circulation. If the bleeding is severe or does not stop, seek veterinary help immediately.

Cleaning the wound is an important step to minimise the risk of infection. Use a mild, sterile saline solution to remove dirt, foreign bodies and germs. Avoid using solutions containing alcohol as these can cause tissue irritation.

If the wound is small and not bleeding heavily, you can protect it with a clean, non-adherent dressing or a sterile compress. Take care not to apply the dressing too tightly so as not to impair circulation. If possible, allow the wound to air dry as this can promote healing.

Even if the wound appears superficial, it is advisable to seek a veterinary assessment. Vets can better assess the severity of the injury and take appropriate action to prevent potential complications. Deeper wounds, bite wounds or facial injuries require particularly prompt attention.

Remember that wounds can cause pain. Avoid touching or straining the animal unnecessarily. Vets can prescribe suitable painkillers to make the animal more comfortable while it heals.

Wounds caused by bites are at increased risk of infections such as tetanus or rabies. Make sure the animal is up to date with vaccinations to minimise these risks.

To summarise, first aid for dog and cat wounds is an important skill for pet owners. By acting calmly and knowledgeably, you can help ensure your pet's wellbeing and promote the best possible healing.

Use of HOCL for wounds in pets

Hypochlorous acid (HOCl) is a disinfectant made from water and salt by electrolysis. It is increasingly used to treat wounds in pets as it has antimicrobial properties and is gentle on the skin. The use of HOCl can be a promising option to prevent infection and promote healing in wounds.

HOCl has broad antimicrobial activity against bacteria, viruses and fungi. It kills harmful microorganisms without damaging the surrounding healthy tissue. This makes it an ideal option for disinfecting wounds as it can reduce infection without interfering with natural wound healing.

A major advantage of HOCl is its tissue-friendliness. Unlike some conventional disinfectants, HOCl does not cause irritation or damage to the skin. This is particularly important when used on sensitive animal skin, such as that of dogs and cats.

The application of HOCl to wounds is relatively simple. Spray the HOCl solution onto the cleaned wound or soak a sterile dressing with it. Leave it to work for a few minutes before carefully dabbing the wound or allowing it to dry. Depending on the severity of the injury, it can be applied several times a day.

HOCl can help to reduce unpleasant odours in infected wounds, which is beneficial for both the pet and the owner. HOCl also has anti-inflammatory properties that can help reduce inflammation in and around the wound. This can promote the healing process and improve the overall well-being of the animal.

Although HOCl is considered safe for use on skin, it is still advisable to monitor the animal's reaction. If irritation or allergic reactions occur, use should be discontinued immediately. Consult a veterinarian if you have any concerns.

It is important to note that HOCl is not a cure-all and may not be suitable for all types of wounds. Deeper or more severe wounds may require additional veterinary intervention such as sutures or other specialised treatments.

The use of HOCl for pet wounds can be a promising addition to wound treatment. Thanks to its antimicrobial properties and tissue-friendliness, HOCl could help prevent infection and promote healing in dogs and cats. However, it should always be used in consultation with a vet, especially for more serious injuries

Conclusion

The comprehensive treatment of wound injuries in dogs and cats requires an individualised approach that takes into account both the physiological differences of the animals and the specific characteristics of the wounds. Immediate and appropriate wound care is essential to prevent serious consequences such as infection, prolonged healing times and complications.

The treatment of wounds requires a balance between traditional methods such as suture closure and modern approaches such as the use of growth factors and biopolymers. Promoting wound healing through appropriate hygiene, inflammation control and pain management plays a central role in the recovery of animals.

The risks of wounds that are not treated immediately or correctly are manifold and range from infection and delayed healing to chronic wounds and serious complications such as septicaemia. Early and appropriate wound care is therefore essential to ensure animal welfare.

The use of hypochlorous acid (HOCl) for wound treatment in pets shows promising benefits such as antimicrobial activity, tissue-friendliness and anti-inflammation. This method could be a valuable addition to existing treatment approaches but requires further research and clinical trials to fully understand its efficacy.

Overall, this work highlights the complexity of wound management in dogs and cats and the importance of taking a holistic view, taking into account modern knowledge and best practice. Close collaboration between pet owners and veterinary professionals is crucial to ensure the best possible care and recovery for animals.
