Anesthesiologist

An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and peri-operative medicine.

However, in the United Kingdom, the term anaesthetist has a broader context and can include both medical and non-medical practitioners—although the latter are often referred to as anaesthetic practitioners. The source further defines an anesthesiologist in the USA as a physician who completes an accredited residency program in anesthesiology, usually four years following medical school. Training in other countries is significantly longer. A nurse anesthetist is a nurse who has acquired graduate-level education and board certification in anesthesia, and may work under the supervision of a physician. Anesthesiologists may administer anesthesia directly or as part of an anesthesia team consisting of nurse anesthetists or anesthesiologist assistants.
