Anesthesia awareness. Awareness under anesthesia, also referred to as intraoperative awareness or accidental awareness during general anesthesia ( AAGA ), is a rare complication of general anesthesia where patients regain varying levels of consciousness during their surgical procedures. While anesthesia awareness is possible without resulting ...
General anaesthesia (UK) or general anesthesia (US) is a method of medically inducing loss of consciousness that renders a patient unarousable even with painful stimuli. [5] This effect is achieved by administering either intravenous or inhalational general anaesthetic medications, which often act in combination with an analgesic and ...
In 1847, Scottish obstetrician James Young Simpson (1811–1870) of Edinburgh was the first to use chloroform as a general anesthetic on a human ( Robert Mortimer Glover had written on this possibility in 1842 but only used it on dogs). The use of chloroform anesthesia expanded rapidly thereafter in Europe.
Anesthesiology or anaesthesiology is the medical specialty 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] A physician specialized in anesthesiology is called an anesthesiologist ...
General anaesthetics (or anesthetics) are often defined as compounds that induce a loss of consciousness in humans or loss of righting reflex in animals. Clinical definitions are also extended to include an induced coma that causes lack of awareness to painful stimuli, sufficient to facilitate surgical applications in clinical and veterinary practice.
Theories of general anaesthetic action. Structures of general anaesthetics widely used in medicine. [ 1] 1 - ethanol, 2 - chloroform, 3 - diethyl ether, 4 - fluroxene, 5 - halothane, 6 - methoxyflurane, 7 - enflurane, 8 - isoflurane, 9 - desflurane, 10 - sevoflurane. A general anaesthetic (or anesthetic) is a drug that brings about a reversible ...
The American Society of Anesthesiologists ( ASA) is an educational, research and scientific association of physicians organized to raise the standards of the medical practice of anesthesiology and to improve patient care. As of 2023, the organization included more than 57,000 national and international members and has more than 100 full-time ...
To determine the depth of anesthesia, the anesthetist relies on a series of physical signs of the patient. In 1847, John Snow (1813–1858) [1] and Francis Plomley [2] attempted to describe various stages of general anesthesia, but Guedel in 1937 described a detailed system which was generally accepted.
