Anesthetists administer gas or inject drugs to artificially induce insensitivity to pain during medical procedures.
Anaesthetist is the term used throughout the world, and particularly in Britain, to designate one who administers an anaesthetic, and includes both nurses and doctors. In Canada, only trained physicians provide anesthetic services, so the Canadian Anaesthetists' Society adopted the designation anesthesiologist to separate physician providers from others.
Nurse anesthetists or certified registered nurse anesthetists (CRNA) are licensed professional nurses (RNs) who undergo extensive training, become nationally certified by exam after graduation, and then provide services similar to an anesthesiologist.
Anesthesiologists are physicians which after medical school, complete a one year internship and a three year residency in anesthesia.
The anesthetist or anesthesiologist may perform some or all of the following tasks:
Perform preoperative evaluations and preparations;
Monitor patient reactions to anesthesia and surgery;
Advise the appropriate physician of adverse reactions;
Manage fluid therapy;
Provide or supervise postoperative recovery care;
Perform postoperative follow-up and patient evaluation;
