What is Local Anesthesia?

A local anesthetic (medication which blocks nerves) is injected around the area of the surgical site. This may be called a "field block." The area blocked is a smaller area than with a regional block. This block is usually saved for small, superficial surgeries, such as removal of skin lesions and placement of long term implantable intravenous lines. Occasionally, the surgeon will give local anesthesia even after general anesthesia to reduce the discomfort at the surgical site after surgery.
