The depth of anesthesia can be changed and recovered if some unexpected situation occurs during surgery. [13] Although inhaled anesthetics will cause an unconscious state in which cats and dogs will not recall or perceive pain, the depth of anesthesia may not prevent the variety of reflex reactions to harmful stimuli during the operation.

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 .
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]
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.
Twilight anesthesia is applied to various types of medical procedures and surgeries. It is a popular choice among surgeons and doctors who are performing anything from minor plastic surgeries to dental work, and procedures that do not require extensive operations or long durations in favor of less nausea and a limited recovery period after surgery.
An example of this is a recognition test, where patients are asked to determine, after surgery, which of a selection of words could be heard during the surgery. The following scenario is an example. Patients were exposed during anesthesia to a list of words containing the word "pension".
After raising alarm about the proposed plan, one major professional group of anesthesiologists said on Friday it was “pleased that Anthem has reversed course on its deeply flawed policy proposal ...
Anesthesia is a combination of the endpoints (discussed above) that are reached by drugs acting on different but overlapping sites in the central nervous system. 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 ...
