Which of the following is a commonly used local anesthetic in food animal practice?

• A. Procaine
• B. Bupivacaine
• C. Lidocaine
• D. Ketamine

Answer: (C)

Lidocaine is a commonly used local anesthetic in food animal practice due to its fast onset and effectiveness in providing localized pain control. It is frequently employed in various procedures, such as minor surgeries and diagnostic procedures, to achieve anesthesia in specific regions of the body. Lidocaine has the advantage of being versatile, with applications in both infiltration and nerve blocks, making it a valuable tool for veterinarians in the field.

In addition to its effectiveness, lidocaine's safety profile and relatively short duration of action allow for good control during procedures without overly prolonging anesthesia. This is particularly important in food animal practice, where rapid recovery and the ability to return animals to normal activities are essential for overall health management and productivity.

In contrast, while procaine and bupivacaine are also local anesthetics, their use is less common in certain food animal practices compared to lidocaine. Procaine, for example, is more often used in equine practices and can cause irritation at the injection site. Bupivacaine has a longer duration of action but carries a higher risk of adverse effects if not used cautiously. Ketamine, on the other hand, is primarily classified as a general anesthetic rather than a local anesthetic, making it less
