Function of infiltration anaesthesia?

Infiltration anesthesia is a type of local anesthesia that involves injecting a small amount of anesthetic solution directly into the tissues surrounding the area to be numbed. This numbs the nerves in the immediate area, providing pain relief during minor surgical procedures or medical treatments. The function of infiltration anesthesia is to block pain signals from reaching the brain, allowing the patient to undergo the procedure without feeling pain.

-Blocks conduction of nerve impulses in a limited area.
-Has rapid onset of action.
-Pain is absent in the infiltrated area.
-Sensory, thermal and motor blockade in the infiltrated area.
