2. A physician who specializes in the administration of pain killers in order to prevent or to cause an insensibility to pain during surgery, birth labor and delivery, or other medical procedures: An anesthesiologist has a medical doctorate whereas an anesthetist does not. An anesthetist is a nurse, or technician, trained to administer anesthetics.
Among some hospital workers, anesthesiologists are known as the "dream team".
"Anesthetics that are administered by anesthesiologists which can affect the whole body by making the patient unconscious are called general anesthetics and anesthetics that make a person have no feeling in only a specific part of the body are called local anesthetics."
