Anesthesia as a noun would be defined as the lack of, or insensitivity to, pain. That insensitivity to pain can be created in many different ways. It can be created with local anaesthetics, it can be created with regional anesthetic, it can be created with inhalational anesthetics, as well as with a potpourri of other medications. It can also be created with acupuncture or hypnosis, or even cold therapy.
