Why is it recommended to block lidocaine away from the incision?

• A. It enhances anesthesia
• B. It minimizes vasodilation and bleeding risks
• C. It improves the effectiveness of the surgery
• D. It increases patient comfort

Answer: (B)

The recommendation to block lidocaine away from the incision primarily aims to minimize vasodilation and bleeding risks during surgical procedures. Administering lidocaine closer to an incision can lead to localized vasodilation, which can increase blood flow to the area. This can result in greater blood loss during surgery, complicating the procedure and potentially affecting the animal's recovery.

By blocking lidocaine away from the incision site, the goal is to create a zone of anesthesia that does not interfere with the localized blood flow directly at the surgical site. This approach helps maintain hemostasis — the process of preventing and controlling bleeding — which is crucial in any surgical procedure. As a result, keeping lidocaine away from the incision site can contribute to a safer surgical environment, as it allows for better management of bleeding while still effectively providing pain relief for the patient.
