For radiographs in a patient with mild FAS and OA, which combination is recommended?

• A. Alpha-2 agonist plus opioid
• B. Acepromazine alone
• C. Benzodiazepine alone
• D. Alpha-2 agonist alone

Answer: (A)

The strategy being tested is using multimodal premedication to both calm the patient and control pain during radiographs. An alpha-2 agonist provides reliable sedation and anxiolysis with muscle relaxation, helping the animal stay still. Adding an opioid delivers strong analgesia, addressing osteoarthritis pain that could otherwise trigger movement or distress during handling. Together, they allow effective in-patient radiography with less stress and improved image quality, while letting you use lower doses of each drug to limit side effects like bradycardia or oversedation.

Using sedatives without analgesia (like acepromazine alone) leaves OA pain untreated and can still result in movement or stress; benzodiazepines alone offer limited sedation and no analgesia; an alpha-2 agonist alone provides some sedation and analgesia but may not adequately manage OA pain or stress during positioning. The combined approach optimally balances comfort, cooperation, and safety for radiographs in a mildly fearful/anxious patient with OA.
