General anesthetics normally are used to produce loss of consciousness before and during surgery. However, for obstetrics (labor and delivery) or certain minor procedures, an anesthetic may be given in small amounts to relieve anxiety or pain without causing unconsciousness.
Every day about 60,000 people nationwide have surgery under general anesthesia. Itâs a combination of drugs thatâs made surgery more bearable for patients and doctors alike. General anesthesia dampens pain, knocks you unconscious and keeps you from moving during the operation.
