Question 1

Why is clinical examination important before rabbit surgery?

Accepted Answer

Clinical examination is essential because rabbits often hide signs of pain or illness, making it difficult to detect underlying health problems. Observation of alertness, posture, gait, and grooming behavior, combined with physical examination of the eyes, nose, ears, teeth, and external genital region, helps identify abnormalities that could affect anesthetic or surgical outcomes.

Question 2

Should rabbits be fasted before anesthesia?

Accepted Answer

Rabbits should generally not undergo prolonged fasting before anesthesia because it may disrupt normal gastrointestinal function and trigger hypoglycemia, a dangerous drop in blood sugar. Pre-anesthetic preparation should follow approved veterinary and institutional protocols to ensure the rabbit's metabolic stability during surgery.

Question 3

What precautions prevent hypothermia during rabbit surgery?

Accepted Answer

Rabbits are particularly prone to hypothermia during anesthesia, so warming devices must be used throughout the procedure. Additionally, for longer surgeries, supportive measures such as fluid therapy and ocular lubrication help maintain hydration and prevent corneal drying while the rabbit's body temperature is regulated.

Question 4

How does the Rabbit Grimace Scale assess pain after surgery?

Accepted Answer

The Rabbit Grimace Scale evaluates five facial action units: orbital tightening, cheek flattening, nostril shape, whisker position, and ear position. Each feature is scored from 0 to 2, with higher scores indicating greater pain severity. Grimace scoring on awake animals, combined with behavioral observations, guides analgesic administration and welfare decisions.

Question 5

What aseptic techniques are used to prepare the surgical site?

Accepted Answer

The surgical site should be clipped, cleaned, and disinfected using aseptic technique to prevent infection. A sterile surgical drape is then applied to establish and maintain a sterile field throughout the procedure, ensuring the surgical area remains free from contamination.

Question 6

What vital signs should be monitored during rabbit surgery?

Accepted Answer

Physiological parameters monitored during surgery include respiratory rate and effort, mucous membrane color, body temperature, and anesthetic depth. Regular assessment of these vital signs throughout the procedure helps ensure the rabbit's safety and allows for prompt intervention if complications arise.

Question 7

What are humane endpoint criteria for rabbits experiencing severe pain?

Accepted Answer

If a rabbit experiences severe or persistent pain that cannot be adequately relieved, humane endpoint criteria should be implemented according to veterinary guidance and institutional protocols. Depending on circumstances, management may include additional supportive care, removal from the study, or humane euthanasia to prevent unnecessary suffering.
