Anesthesiologists are medical doctors who specialize in
anesthesiology, which is the use of pain-blocking techniques or medicines
(anesthetics) during surgery and other medical procedures.
An anesthesiologist may administer medicine that numbs the area
of the body where a procedure is being performed (local or regional
anesthesia), inject medicine into the spinal canal to numb an area of the body
(spinal or epidural anesthesia), or make sure a person is unconscious and
pain-free during a procedure (general anesthesia) while also monitoring heart
rate, breathing, and blood pressure. An anesthesiologist may also supervise a
nurse anesthetist. Anesthesiologists can further specialize in critical care
medicine, pain management, pediatrics, or obstetrics.
Anesthesiologists can be board-certified through the Board of
Anesthesiology, which is recognized by the American Board of Medical
