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 .
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 ...
In the United Kingdom, deep sedation is considered to be a part of the spectrum of general anesthesia, as opposed to conscious sedation. In addition to the aforementioned precautions, patients should be interviewed to determine if they have any other condition that may lead to complications while undergoing treatment.
General anesthetics elicit a state of general anesthesia. It remains somewhat controversial regarding how this state should be defined. [2] General anesthetics, however, typically elicit several key reversible effects: immobility, analgesia, amnesia, unconsciousness, and reduced autonomic responsiveness to noxious stimuli.

Twilight anesthesia is an anesthetic technique where a mild dose of sedation is applied to induce anxiolysis (anxiety relief), hypnosis, and anterograde amnesia (inability to form new memories). The patient is not unconscious, but sedated.
Full wakefulness and general anesthesia are the two extremes of the spectrum. Conscious sedation and monitored anesthesia care (MAC) refer to an awareness somewhere in the middle of the spectrum, depending on the degree to which a patient is sedated. Monitored anesthesia care involves titration of local anesthesia along with sedation and ...
Procedural sedation and analgesia (PSA) is a technique in which a sedating/dissociative medication is given, usually along with an analgesic medication, in order to perform non-surgical procedures on a patient. The overall goal is to induce a decreased level of consciousness while maintaining the patient's ability to breathe on their own.
Total intravenous anesthesia (TIVA) refers to the intravenous administration of anesthetic agents to induce a temporary loss of sensation or awareness. The first study of TIVA was done in 1872 using chloral hydrate , [ 1 ] and the common anesthetic agent propofol was licensed in 1986.
