Postanesthetic shivering is one of the leading causes of discomfort in patients recovering from general anesthesia. It usually results due to the anesthetic inhibiting the body's thermoregulatory capability, although cutaneous vasodilation (triggered by post-operative pain) may also be a causative factor.
Postoperative nausea and vomiting (PONV) is the phenomenon of nausea, vomiting, or retching experienced by a patient in the post-anesthesia care unit (PACU) or within 24 hours following a surgical procedure. PONV affects about 10% of the population undergoing general anaesthesia each year. PONV can be unpleasant and lead to a delay in ...
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 ...
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.

Determining when patients can be safely discharged from the post-anesthesia care unit. Aldrete's scoring system is a commonly used scale for determining when postsurgical patients can be safely discharged from the post-anesthesia care unit (PACU), generally to a second stage (phase II) recovery area, hospital ward, or home.
Age, duration of anaesthesia, introperative complications, and postoperative infections were found to be associated with POCD. [3] POCD is just as likely to occur after operations under regional anesthesia as under general anesthesia. [2] [4] More likely after major operations than minor operations. [9] [11]
A research study of 400 adult patients emerging from general anesthesia in the PACU were assessed for delirium using the Confusion Assessment Method for the ICU (CAM-ICU) found rates of emergence delirium of 31% at PACU admission with rates declining to 8% by 1 hour.
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.
