Management of thermal injuries in large animals.

The researchers discuss the management, treatment and challenges of thermal burns in large animals, noting that their anatomy and response to injury is similar to humans. They underscore the importance of accurately assessing both local and systemic effects of severe burns, treating adversity in time, and adapting strategies to suit the specific challenges in veterinary hospitals.

Similarities to Human Burns

• The study outlines that large animals, much like humans, experience thermal burns of varying degrees. Depending on the depth of the thermal damage, burns can be broadly categorised as first, second (superficial and deep), third, and fourth degrees.
• In severe cases, burns elicit both local and systemic responses. Locally, the injured area displays signs of inflammation, vasospasm fluid accumulation, and electrolyte shifts. Systemically, the animal might face issues like hypovolemia, fluid and electrolyte loss, protein loss, pulmonary edema, increased caloric requirements, and weakened immune responses.

Evaluation and Treatment

• For effective treatment, the researchers stress the necessity to gauge the total impact on the animal, investigating all physical conditions rather than just focusing on the wound.
• The burn depth must be estimated accurately, as it directly influences the course of treatment. However, accurate evaluation often gets delayed by a few days, specifically in large animals.
• Treatment methods must address evaporative fluid and electrolyte loss, protect against mechanical injury, stave off bacterial invasion, maintain body temperature, and remove non-viable tissue, sparing viable germinal tissue for healing.

Unique Challenges

• Despite the similarities to human pathophysiology, management of burns in large animals comes with specific difficulties. A common problem is the large surface area often involved in burns, leading to substantial fluid, electrolyte, and caloric loss.
• Most veterinary hospitals are not equipped to control the patient’s environment adequately, posing significant risk of extensive bacterial contamination.
• Patient restraint is critical to prevent additional injuries to the healing wound. Furthermore, many animals may experience itching, requiring precautions to prevent self-inflicted harm.
• Additional constraints include the lack of technically trained personnel capable of properly monitoring and treating burn patients.
