For a monkey requiring examination of facial anatomy, which anesthetic agent is commonly used?

• A. Ketamine
• B. Isoflurane
• C. Propofol
• D. Sevoflurane

Answer: (A)

For a monkey needing examination of facial anatomy, you want a fast-acting, reliable way to immobilize without overwhelming respiratory support needs. Ketamine fits well because it induces anesthesia quickly and provides analgesia while preserving reflexes and spontaneous breathing. This dissociative state helps the animal stay still enough for a facial exam, and its cardiovascular effects are relatively predictable and mild compared with deeper sedatives, which is safer for a short procedure. In practice, ketamine is often used with a sedative or muscle-relaxant (such as a benzodiazepine or an alpha-2 agonist) to smooth induction, enhance muscle relaxation, and reduce salivation, leading to a steadier exam with easier handling and faster recovery. Inhalant agents like isoflurane or sevoflurane require an anesthesia machine and endotracheal access for maintenance, which is more than needed for a quick facial assessment. Propofol can be used but carries a higher risk of apnea and blood pressure drop, especially in smaller primates. Ketamine offers a practical balance of rapid onset, reliable immobilization, analgesia, and safer short-term respiratory and cardiovascular profile for this specific procedure.
