Anesthesia is a way to control pain using anesthetic medicine. General anesthesia, which can be injected into a vein or inhaled, affects the entire body and makes the person unconscious.
A person under general anesthesia is completely unaware of what is going on and does not feel pain during the surgery or procedure. Anesthesia interrupts the pain signals between a person's nerve endings and the brain. The health professional administering the anesthesia monitors the person's condition throughout the procedure.
