What is an anesthetic?

Piedmont Heart Institute

An anesthetic is a drug or other substance that causes a loss of feeling or awareness. Local anesthetics cause a loss of feeling in one small area of the body. Regional anesthetics cause a loss of feeling in a part of the body, such as an arm or leg. General anesthetics cause a loss of feeling and a complete loss of awareness that feels like a very deep sleep.

This answer is based on source information from The National Cancer Institute.
