What are some considerations when using fentanyl intraoperatively in Fear Free protocols?

• A. Provides rapid analgesia; requires careful dosing and monitoring; potential for respiratory depression; be prepared to adjust or stop infusion.
• B. Provides slow analgesia; requires no monitoring.
• C. Causes permanent sedation.
• D. Does not affect respiration.

Answer: (A)

Fentanyl given during surgery is valued for rapid, potent analgesia that can be titrated to the animal’s needs, which fits Fear Free goals of promptly controlling pain to reduce stress. Because it is a powerful opioid, dosing must be precise and adjusted as the surgical course and depth of anesthesia change, with vigilant monitoring of the patient. Respiratory depression is a major risk, so continuous observation of breathing effort, oxygenation, and, if available, capnography is essential. Be ready to slow, pause, or stop the infusion and support ventilation if signs of hypoventilation or hypoxemia appear. Fentanyl effects can deepen with other anesthetics, so coordinate dosing within the overall anesthetic plan and consider multimodal analgesia to limit opioid exposure. Have reversal options like naloxone available if needed, and be mindful of potential hemodynamic effects such as hypotension or bradycardia. The statement describing rapid analgesia with careful dosing and monitoring while acknowledging respiratory depression and the need to adjust or stop the infusion best captures the safe, practical approach in Fear Free intraoperative use.

The other descriptions are inconsistent with how fentanyl works or should be managed: it does not provide slow analgesia, it does require monitoring, its effects are not permanent sedation, and it does affect respiration.
