Burns in Reptiles

Filed Under: Reptiles, General Care

The most common type of burns seen in captive reptiles are thermal and are usually attributed to an abnormally hot heat source, one from which the animal cannot escape. Captive reptiles should always be provided a basking spot, but the enclosure should be large enough that the reptile may retreat to cooler areas if and when the radiating heat becomes too intense. In the wild, thermal burns may be encountered when the reptile has survived a grass or forest fire. Chemical burns may also occur, typically from cleaning solutions used to sanitize the enclosure of a captive reptile.

Regardless of the source of injury, the area should be profusely irrigated with sterile saline. Cold-water rinses or cold compresses may be used to further limit the tissue destruction. Ice should never be used as a compress because the ice may cause further damage to the involved tissues.

Silver Sulfadiazine or Silvadene® cream is an ointment extensively used in burn patients. The cream is both a broad spectrum antibiotic and an antifungal agent with cooling affects on the skin. The cream is inexpensive and relatively non-toxic. Systemic (oral or injectable) antibiotics are not effective in preventing wound infection and are only used in cases of sepsis.

Placement of a transparent adhesive drape or an absorbent wound dressing over the wound will protect the area and discourage the invasion of the site by secondary bacterial contamination.

Burns should not be closed surgically and in fact will rarely hold sutures. Since reptile skin is so closely adhered, skin grafting is not a viable option. Most burns must heal by secondary intention (not sutured closed) through the promotion of healthy granulation tissue (a collection of capillaries, fibroblasts and inflammatory cells that act together to repair a wound). Skin repair from burns is slow and may result in severe scarring.

By their nature burns are quite painful and analgesia should be given as necessary. The injured area will also result in plasma loss and fluid therapy may be necessary, especially in severe cases.

  • Bite wounds most commonly occur in reptiles when live rodents are left in cages with a reptile that does not want to eat the rodent, regardless of the reason. The rodent will then often gnaw on the reptile. Rodents may also bite in self-defense when they are seized by a reptile in any manner that fails to induce immediate death. Wounds made in self-defense tend to involve the head, mouth and face of the snake.

  • Inflammation of the tissues in the mouth is defined as infectious stomatitis, more commonly known as mouth rot. The initiating cause may be stress or trauma, both of which lead to an infection of the oral cavity by opportunistic pathogenic bacteria. Common types of bacteria isolated from this area include Pseudomonas, Aeromonas, Klebsiella, and Salmonella. In some cases, mycobacteria, and some species of fungi, or some viruses may also become involved.

  • Collectors of reptiles and amphibians need to replicate the natural environment of their pets as close as possible. Humidity is an essential ingredient in the creation of a natural setting. Humidity affects all aspects of life and may affect growth, reproduction and even the general health of any confined species.

    Acceptance of water depends in part on the species in question. Turtles, snakes and many lizards will drink from bowls. Turtles and snakes sip, while lizards will lap. Anoles, chameleons and day geckos lap from droplets sprayed or dripped onto foliage.

  • Iguanas are a very popular reptile pet. With very gradual introduction to handling, a young iguana can adapt well to human contact. Iguanas are fascinating to watch and, as a somewhat low-maintenance pet, they are popular with people who may not have the time or space to dedicate to a larger, more demanding animal. But that’s not to say that iguanas don’t need their share of care. A happy iguana is well-fed, well-housed and healthy.

  • Have you ever had an itch that was driving you insane? You just could not leave it alone even though the skin was becoming irritated? You may even scratch at the area so bad that you caused it to bleed. Everyone was trying to advise you not to scratch and yet you somehow just could not leave it alone. Sounds like a pet with a hot spot, or “acute moist dermatitis.”
