  2. General anaesthesia - Wikipedia

    en.wikipedia.org/wiki/General_anaesthesia

    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 ...

    en.wikipedia.org/wiki/General_anaesthetic

    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.

  4. Anesthesia - Wikipedia

    en.wikipedia.org/wiki/Anesthesia

    General anesthesia (as opposed to sedation or regional anesthesia) has three main goals: lack of movement , unconsciousness, and blunting of the stress response. In the early days of anesthesia, anesthetics could reliably achieve the first two, allowing surgeons to perform necessary procedures, but many patients died because the extremes of ...

    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.

    Two weeks later, Morton became the first to publicly demonstrate the use of diethyl ether as a general anesthetic at Massachusetts General Hospital, in what is known today as the Ether Dome.

    en.wikipedia.org/wiki/Outline_of_anesthesia

    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.

  8. Anesthesiology - Wikipedia

    en.wikipedia.org/wiki/Anesthesiology

    Anesthesiology, anaesthesiology or anaesthesia 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]

  9. Total intravenous anaesthesia - Wikipedia

    en.wikipedia.org/wiki/Total_intravenous_anaesthesia

    TIVA is used to induce general anesthesia while avoiding the disadvantages of volatile anesthesia (and traditional inhalation agents). [9] Intravenous anesthetic agents are titrated at safe doses to maintain stage III surgical anesthesia (unconsciousness, amnesia, immobility, and absence of response to noxious stimulation). [10]
