An effective treatment for post-burn pruritus will also be effective in other neuropathic and intractable itching. The second one is the intact nociceptor hypothesis. The first one is peripheral sensitization. There are two mechanisms underlying post-burn neuropathic pruritus. When keratinocytes are activated by an itch-inducing substance, they secrete a variety of inflammatory substances that increase the susceptibility of the itch receptor. During wound healing, various neuropeptides secreted from the nerves of the skin control epidermal and vascular proliferation and connective tissue cells. Clinically, post-burn pruritus tends to be intractable to conventional treatment but rather responds to neuroleptic agents, such as gabapentin and pregabalin. The precise mechanism of post-burn pruritus has not been elucidated, but it appears to have pruritogenic and neuropathic aspects. Many potential treatments are available for pruritus but there is no consensus of the best single treatment yet. The post-burn pruritus is a common and serious complication of burn injury, which severely lowers the quality of life of the patient. Work with your vet to determine the cause of the hives, using both your dog’s health history and history of exposure to allergens.Post-burn pruritus is the pruritus that occurs after burn during the rehabilitation and healing process of burn wounds. Injectable medications and intravenous fluids (in very serious cases)Ĭold compresses over the hives or swollen areas to give relief from itchingĪntihistamines, but only under the supervision of your vet Beyond the physical examination, other parts of the diagnosis include:Īny history you are able to provide be as thorough as you can in describing allergens your dog might have come into contact with and when and where you first saw the hivesĭogs with hives usually respond quickly to treatment, which may include:Īntihistamine (oral or injectable) and a steroid Wheals typically have hair on them, and may appear in clusters. Your vet will closely examine your dog to locate the distinctive wheals associated with hives. Insects bites, chemical contact, and medications are the most common. Insect stings/bites (often involving the head and neck of your pup) Any allergen your dog is sensitive can also lead to hives. The allergen that causes the hives may be environmental, chemical, or dietary. Swelling (angioedema), which is particularly concerning when it involves the face and respiratory system and can have severe and life-threatening consequences Red raised areas of skin called wheals, which can occur anywhere (including mucous membranes) but are most commonly seen on the head, neck, back, abdomen, and legsĮxcessive drooling if the mouth is swollen This is especially true for hives that occur on the face or around the throat, which can lead to dangerous swelling and possible blockage of the airways. However, because of the risk that the reaction can worsen to dangerous swelling of your dog’s airways or a serious allergic reaction called anaphylaxis, you should seek out treatment any time you see hives on your dog. In mild cases, the hives will generally disappear within 12-48 hours after contact with the allergen. Wheals can appear anywhere on your dog’s body, but they’re usually found on the head, neck, back, stomach, and legs. The raised red area of the skin is referred to as a “wheal,” and it can appear anywhere from a few minutes to hours after exposure to an allergen. Hives can appear very quickly-and disappear just as quickly. They’re a sign that an allergy is causing the immune system to overreact. Just as with humans, hives can be very itchy for your dog. Hives (also referred to as urticaria) are areas of the skin that appear reddened and raised.
