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.
Anesthesia is medication administered for the relief of pain and sensation during surgery. The type and dosage of anesthesia is administered by the anesthesiologist. When a patient faces surgery, he or she will meet with the anesthesiologist or nurse anesthetist before the procedure. The anesthesiologist will review the patient's medical condition and history to plan the appropriate anesthetic for surgery.
