HOW DO PARENTERAL LOCAL ANESTHETICS WORK?

Parenteral local anesthetics are administered using an injection to cause loss of sensation before minor surgery.

Local anesthesia causes the temporary loss of sensation, including pain, without depressing the consciousness. It acts within nerve fibers to inhibit the rapid inflow of sodium necessary for impulse generation. When there is no impulse generation, there is no transmission of pain around that area. Also, there is a loss of sensation around that area.
