A lower MAC value represents a more potent volatile anesthetic. Other uses of MAC include MAC-BAR (1.7–2.0 MAC), which is the concentration required to block autonomic reflexes to nociceptive stimuli, and MAC-awake (0.3–0.5 MAC), the concentration required to block voluntary reflexes and control perceptive awareness.
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 ...
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 .
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.
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]
Balanced anesthesia can make patients calm by using drugs such as: medetomidine, diazepam or midazolam, and acepromazine. [18] Keeping patients calm prior to surgery can avoid the unpredictable consequences of stress, such as tachypnea, hypertension and tachycardia which may be harmful to the anesthetized patients. [18]
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.
Sedation is the reduction of irritability or agitation by administration of sedative drugs, generally to facilitate a medical procedure or diagnostic procedure. Examples of drugs which can be used for sedation include isoflurane, diethyl ether, propofol, etomidate, ketamine, pentobarbital, lorazepam and midazolam. [1]
