Individual general anesthetics vary with respect to their specific physiological and cognitive effects. While general anesthesia induction may be facilitated by one general anesthetic, others may be used in parallel or subsequently to achieve and maintain the desired anesthetic state. The drug approach utilized is dependent upon the procedure ...
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 .
Structures of general anaesthetics widely used in medicine. [1] 1 - ethanol, 2 - chloroform, 3 - diethyl ether, 4 - fluroxene, 5 - halothane, 6 - methoxyflurane, 7 - enflurane, 8 - isoflurane, 9 - desflurane, 10 - sevoflurane. A general anaesthetic (or anesthetic) is a drug that brings about a reversible loss of consciousness. [2]
General anesthesia suppresses central nervous system activity and results in unconsciousness and total lack of sensation, using either injected or inhaled drugs. Sedation suppresses the central nervous system to a lesser degree, inhibiting both anxiety and creation of long-term memories without resulting in unconsciousness.
Unlike the intravenous anesthetic drugs previously mentioned, ketamine produces profound pain relief, even in doses lower than those that induce general anesthesia. [11] Also unlike the other anesthetic agents in this section, patients who receive ketamine alone appear to be in a cataleptic state, unlike other states of anesthesia that resemble ...
To induce general anesthesia, propofol is the drug used almost exclusively, having largely replaced sodium thiopental. [13]It is often administered as part of an anesthesia maintenance technique called total intravenous anesthesia, using either manually programmed infusion pumps or computer-controlled infusion pumps in a process called target controlled infusion (TCI).

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.
