During recovery, sighthounds are prone to which thermoregulatory change?

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

Answer: (B)

After anesthesia, sighthounds can show a tendency toward hyperthermia during recovery. This breed group often has a lean build with little insulating fat and a high surface area relative to body mass, so they can generate heat quickly as they awaken and become active. If the recovery environment is warm and there is ongoing muscular activity or stress, heat production can exceed the animal’s ability to dissipate it, leading to a rise in core temperature. That’s why hyperthermia is the pattern you may see during recovery in these dogs. In practice, keep the recovery area moderately cool, monitor temperature closely, and avoid excessive warming measures. If temperature rises, take steps to facilitate cooling and reassess analgesia, activity level, and environmental conditions. Hypothermia is more typical during the intraoperative period, while normothermia or fever-like pyrexia are less characteristic specifically of the recovery phase in sighthounds.
