Thermal Injury: Garden Hose Scalding Syndrome

By Dr. Chanran Ganta

Causes of Thermal Injury

Thermal injury in domestic animals is not uncommon; sources include hot liquids, steam, heating pads, hair dryers, drying cages, hot metals such as wood stoves or car engines, fires, friction from rope “scalds,” electrical burns from chewing electrical wires, improperly grounded electrocautery units, or lightning strikes. Short term exposure to extremely hot temperatures (e.g. 1 s, 68 °C⁄155°F) and prolonged exposures to lower temperatures (e.g. 5 min, 48.9°C⁄120°F) can produce similar injuries.

Garden Hose Scalding Syndrome

Lesions often manifest on the dorsum of the skin with second or third degree burns and are always linked with a history of the pet being hosed on a hot day with a hose exposed to the sun. The clinical signs of scald injuries usually do not manifest for several days; therefore, the owners may not remember the clinical history. Gross lesions are typical of severe thermal burns that are spread linearly on the dorsum (Figure 1). Changes in the skin include marked erythema, ulceration, edema, and cutaneous necrosis with secondary bacterial infection.

Clinical Features and Diagnostic Criteria

The following five criteria are used to diagnose this condition:

  1. Clinical history: the dog had been hosed off with water from a garden hose
  2. Lesion distribution: linear burn pattern along the dorsum
  3. Gross and histological appearance: second or third degree thermal burn
  4. Time of year: May to August
  5. Geographical location: areas where recorded high temperatures were above 32°C (90°F), such as in the western or southern USA.

Summary

Surgical biopsy of all thermal injuries will help in evaluating the size and depth of the injury, which helps to classify the degree of the burn and its prognosis. All biopsy submissions require adequate clinical history, age of the pet, location of the biopsies following proper biopsy collecting techniques.
