What is an indication for using local infiltration anesthesia in food animals?

• A. Extensive surgical procedures
• B. Hoof surgeries or minor repairs
• C. Emergency trauma surgeries
• D. Prolonged immobilization

Answer: (B)

Local infiltration anesthesia is particularly indicated for procedures that are less extensive and where a targeted area of pain control is needed. In food animals, hoof surgeries or minor repairs often involve localized discomfort such as lameness or injuries that can be effectively managed using this technique. Local infiltration allows for a precise anesthesia of the site without affecting the animal's overall systemic condition, making it ideal for less invasive procedures.

In contrast, extensive surgical procedures often require more comprehensive anesthesia protocols, including general anesthesia or regional anesthesia, due to the complexity and invasiveness involved. Emergency trauma surgeries typically necessitate a rapid response and often require more profound analgesia, which local infiltration may not provide sufficiently. Prolonged immobilization, on the other hand, may benefit from alternatives that provide longer-lasting analgesia and muscle relaxation, as local infiltration is generally more suitable for short procedures.
