Anaesthesiology, anesthesiology, anaesthesia or anaesthetics is the medical speciality concerned with the total perioperative care of patients before, during and after surgery.[1] It encompasses anesthesia, intensive care medicine, critical emergency medicine and pain medicine.[2]

Terminology

Various names are used for the specialty, and those who practise it, in different parts of the world:

  • In North America and China, the medical study and application of anesthetics is called anesthesiology,[3][4], and a physician in the specialty is called an anesthesiologist. The word "anesthetist" is used to refer to non-physician providers of anesthesia services such as nurse anesthetists.
  • In several countries that are current or former members of the Commonwealth of Nations–namely, United Kingdom, Australia, New Zealand, Ireland and South Africa–the medical specialty is instead referred to as anaesthesia or anaesthetics, with an extra "a".[4][5] As such, in these countries the same term may be used to refer to the overall medical specialty, the medications and techniques that are used, and the resulting state of loss of sensation. The term anaesthetist is used only to refer to a physician practising in the field; non-physicians involved in anaesthesia provision use other titles in these countries, such as "physician assistant".[6]
  • In most other parts of the world, the spelling anaesthesiology is most commonly used when writing in English, and a physician practising it is termed an anaesthesiologist.[4] This is the spelling adopted by the World Federation of Societies of Anaesthesiologists and most of its most of its member societies, as well as the European Society of Anaesthesiology, and it is the most commonly used term found in the titles of medical journals.[4]

History

Over the past 100 years, the study and administration of anesthesia has become more complex. Historically anesthesia providers were almost solely utilized during surgery to administer general anesthesia in which a person is placed in a pharmacologic coma. This is performed to permit surgery without the individual responding to pain (analgesia) during surgery or remembering (amnesia) the surgery.

About

Many procedures or diagnostic tests do not require "general anesthesia" and can be performed using various forms of sedation or regional anesthesia, which can be performed to induce analgesia in a region of the body. For example, epidural administration of a local anesthetic is commonly performed on the mother during childbirth to reduce labor pain while permitting the mother to be awake and active in labor & delivery.

USA

In the United States, anesthesiologists may also perform non-surgical pain management (termed pain medicine) and provide care for patients in intensive care units (termed critical care medicine).

Training

In the United States, anesthesiologists attend four years of medical school to earn either a Doctor of Medicine (MD) degree or a Doctor of Osteopathic Medicine (DO) degree and then follow it with four years of residency. Certified Registered Nurse Anesthetists or CRNAs are advanced practice registered nurses with additional post-graduate training in anesthesia. By 2025, all CRNA programs will require a doctorate degree. In the United States, the most common anesthesia care model is where an anesthesiologist and Certified Registered Nurse Anesthetist work as a team (termed medical direction or medical supervision). In 17 states, CRNAs can practice without the supervision of a physician (though physician does not dictate it be an anesthesiologist). [7]

Knowledge

Effective practice of anesthesiology requires several areas of knowledge by the practitioner, some of which are:
