The exam takes the form of a written Short-Answer Question (SAQ) paper (3 hours, 12 questions), and a Multiple-Choice Question (MCQ) paper (3 hours, 60 five stem questions covering medicine, surgery, intensive care, pain and basic sciences and 30 Single Best Answer clinical questions) [3] which can be attempted at several regional centres in the UK (such as Edinburgh, Belfast, Birmingham ...
Preanesthetic assessment (also called preanesthesia evaluation, pre-anesthesia checkup (PAC) or simply preanesthesia) is a medical check-up and laboratory investigations done by an anesthesia provider or a registered nurse before an operation, to assess the patient's physical condition and any other medical problems or diseases the patient might have. [1]
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.

The Meyer-Overton correlation for anaesthetics. A nonspecific mechanism of general anaesthetic action was first proposed by Emil Harless and Ernst von Bibra in 1847. [9] They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia.
General anaesthesia (UK) or general anesthesia (US) is medically induced loss of consciousness that renders a patient unarousable even by painful stimuli. [5] It is achieved through medications, which can be injected or inhaled, often with an analgesic and neuromuscular blocking agent .
When asleep or under general anesthesia, the pattern of activity changes. Overall, there is a change from higher-frequency signals to lower-frequency signals (which can be shown by Fourier analysis ), and there is a tendency for signal correlation from different parts of the cortex to become more random.
You’ll arrive at your appointment with clean, product-free hair. In many cases, donor sites will be shaved pre-surgery. You’ll most likely get local anesthesia to numb your scalp but will ...
Anesthesia – pharmacologically induced and reversible state of amnesia, analgesia, loss of responsiveness, loss of skeletal muscle reflexes or decreased sympathetic nervous system, or all simultaneously. This allows patients to undergo surgery and other procedures without the distress and pain they would otherwise experience.
