Why is preoperative fasting used before general anaesthesia in many adult dogs and cats?
Correct answer: B. To reduce regurgitation and aspiration risk
- A. To increase postoperative wound contraction
- B. To reduce regurgitation and aspiration risk
- C. To prevent all anaesthetic hypotension
- D. To accelerate absorption of injectable drugs
Explanation
Fasting reduces the volume of stomach contents and therefore lowers the risk of regurgitation and aspiration during anaesthesia. It does not completely prevent hypotension or directly improve wound contraction and drug absorption.
