Anaesthesiology or anaesthesia is medical specialist concerned involved in the overall perioperative care of patients before, during and after surgery. This includes the fields of anaesthetics, intensive care medicine, emergency medicine and analgesia medicine. Anaesthesiology specialists are called anaesthesiologists or anaesthetists in some countries. (In some countries, these terms are effectively synonymous, but in others they refer to different locations, and the term anaesthesiologist is used only by non- physicians such as anaesthesiologists).
A core element of the discipline is the research and use of anaesthetics to safely support important patient functions during the perioperative period. Since the 19th century, anaesthesiology has evolved from an experimental discipline where non-specialist physicians use new untested drugs and techniques to a highly developed, safe and effective medical discipline. In some countries anaesthesiologists comprise the largest single cohort of doctors in hospitals, and their role can extend far beyond the traditional role of anaesthesia care in the operating room, including fields such as providing prehospital emergency medicine, running intensive care units, transporting critically ill patients between facilities, and rehabilitation programs to optimize patients for surgery
The word “anaesthesia” appears to have first been used in the modern medical sense of the word by Oliver Wendell Holmes Sr. in 1846, and it gained currency when adopted by James Young Simpson the following year. “Anaesthesiology” was proposed in 1889 by Henry William Blanc, and was again coined by Mathias Joseph Seifert in 1902. The name derives from the Ancient Greek In North America, the specialty is referred to as anaesthesiology and a physician of that specialty is called an anaesthesiologist. In these countries, the word “anaesthetist” is used to refer to advanced non-physicians providers of anaesthesia services such as nurse anaesthetists and anaesthesiologist. In some countries that are current or former members of the Commonwealth of Nations–namely, United Kingdom, Australia, New Zealand and South Africa–the medical specialty is instead referred to as anaesthesia or anaesthetics, with an extra “a” As such, in these countries the same term may refer to the overall medical specialty, the medications and techniques that are used, and the resulting state of loss of sensation. The term anaesthesiologist is used only to refer to a doctor who is practicing in the field. Non- physicians involved in the provision of anaesthetics use other titles in these countries. “Doctor assistant”. In some countries that previously used “anaesthesia” and “anaesthesiologist”, such as Ireland and Hong Kong, we switched to “anaesthesiology” and “anaesthesiologist”
Over the last 100 years, the study and management of anaesthesia has become more complex. Historically, anaesthesia providers have been used almost exclusively during surgery to provide general anaesthesia that puts a person into a pharmacological coma. This is done to enable surgery without the person reacting to pain (analgesia) or remembering surgery during surgery (amnesia). In the 19th century, the beginning of general anaesthesia began with the introduction of ether in Boston and chloroform in the United Kingdom to induce unconsciousness and numbness to the pain of surgical injuries. With the isolation of cocaine in the mid-1800s, local anaesthetics became available. Towards the end of the 19th century, the number of pharmacological options increased and they began to be applied to both peripheral and neural axes. Then, in the 20th century, neuromuscular blockade allowed anaesthesiologists to completely paralyze the patient pharmacologically and breathe the patient by mechanical ventilation. With these new tools, anaesthesiologists can centrally control the patient’s physiology and create intensive care drugs that are closely associated with anaesthesiology in many countries.
Many procedures or diagnostic tests do not require “general anaesthesia” and can be performed using various forms of sedation or local anaesthesia that can be administered to induce analgesia in the body area. For example, during labour, the mother usually receives epidural administration of a local anaesthetic to relieve the labour and at the same time allow the mother to wake up and become active during labour and delivery. In the United States, anaesthesiologists can also provide non- surgical pain management (called pain treatment) and treatment of patients in the intensive care unit (called critical care medicine).
