A: Lidocaine is an anesthetic or numbing agent when used topically or injected in the spinal column, and it is an antiarrhythmic (helps with irregular heart beats) when given intravenously. When it is used topically on the skin, it works by inhibiting the nerve impulses that pass along pain signals to the brain.
Lidocaine injection is injected into a vein through an IV to treat heart rhythm problems. When used as a numbing medicine, lidocaine injection is injected through the skin directly into the body area to be numbed. Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely while you are receiving lidocaine injection in a hospital setting.
