A serious problem that arises in performing surgery on cats and small dogs is the additional heat loss produced from an open body cavity.
For these small animals, this type of surgery effectively doubles the normal heat loss rate. If the anesthetic used depresses the BMR of a 5.00 kg dog by 50.0%, estimate the resulting reduction in the animal's body temperature from its normal body temperature of 102°F (39.2°C) during 2.00 h of
a. Minor surgery not requiring the body cavity to be opened.
b. Major surgery requiring an open body cavity procedure. Assume the body of the dog has a specific heat of 4.17 kJ/(kg · K).
