Anesthesiology, anaesthesia or anaesthetics is the medical speciality that focuses on perioperative medicine and the administration of anesthesia.
Terminology varies between countries. In North America, the medical speciality is called anesthesiology, a doctor practising it is termed an anesthesiologist, and the treatment delivered is referred to as anesthesia.[1] By contrast, in the United Kingdom and other countries following the British tradition, both the medical speciality and the treatment delivered are referred to as anaesthesia or anaesthetics, and the physician who performs them is termed an anaesthetist (in North America, the word anesthetist indicates a nurse anesthetist who delivers anesthesia under the supervision of a physician).
One of the fundamental practices of anesthesiologists is that of general anesthesia in which a person is placed in a medical coma. This is performed to permit surgery without the individual responding to pain (analgesia) during surgery or remembering the surgery.
If general anesthesia is not necessary, then regional anesthesia can be performed to induce analgesia in a regional of the body. For example, epidural administration of a local anesthetic is commonly performed on the mother during childbirth to reduce the pain while permitting the mother to be awake and active in labor & delivery (general anesthesia would not permit this).
Anesthesiologists often also undertake non-surgical pain relief and critical care management that includes working in an intensive care unit.[1]

Training
In the United States, anesthesiologists attend 4 years of medical school and then follow it with 4 years of residency. Nurse anesthetists are registered nurses with additional post-graduate training in anesthesia with at least one year of work experience in an intensive care unit, who work under the supervision of an anesthesiologist.
Knowledge
Effective practice of anesthesiology requires several areas of knowledge by the practitioner, some of which are:
- Pharmacology of commonly used drugs including inhalational anaesthetics, topical anesthetics, & vasopressors as well as numerous other drugs used in association with anesthetics (e.g., ondansetron, glycopyrrolate)
- Monitors: electrocardiography, entropy monitoring, neuromuscular monitoring
- Mechanical ventilation
- Anatomical knowledge of the nervous system for nerve blocks, etc.
- Other areas of medicine (e.g., cardiology) to assess the risk of anesthesia to adequately have informed consent
