During maintenance anesthesia, sighthounds are prone to which condition?

• A. Hypothermia
• B. Hyperthermia
• C. Normothermia
• D. Pyrexia

Answer: (A)

The main idea is how anesthesia affects a dog’s ability to regulate temperature and how body build influences heat loss. Sighthounds have a very lean body with little insulating fat and a large surface area relative to their weight. That combination makes them lose heat to the surrounding environment more quickly. Anesthesia further dampens the body's heat production and impairs thermoregulation, and the operating room is often cool. All of this means core temperature can fall rapidly during maintenance, so hypothermia is the usual risk for these breeds. Preventing it relies on active warming strategies, such as forced-air warming, warming IV fluids, and maintaining a warmer ambient temperature, with careful temperature monitoring. Hyperthermia or fever wouldn’t be expected from anesthesia alone in these dogs; they’re not prone to heat buildup under standard maintenance.
