None of the agents currently in use are ideal, although many have some of the desirable characteristics. For example, sevoflurane is pleasant to inhale and is rapid in onset and offset. It is also safe for all ages. However, it is expensive (approximately 3 to 5 times more expensive than isoflurane), and approximately half as potent as ...
Inhalation sedation with nitrous oxide/oxygen is a well recognised safe and effective technique. The desirable effect of the procedure is to relax the patient while maintaining verbal contact. Compared to other sedation agents, it causes minimal physiological stress to the patient and risk of loss of consciousness is less likely.
On appeal, the High Court took the view that, even though glue and plastic bags might be perfectly legal, everyday items, the two shopkeepers knew perfectly well that the children were going to use the articles as inhalants and the charge on the indictment should stand. [26]
Sevoflurane is an inhaled anesthetic that is often used to induce and maintain anesthesia in children for surgery. [17] During the process of awakening from the medication, it has been associated with a high incidence (>30%) of agitation and delirium in preschool children undergoing minor noninvasive surgery.

Halothane, sold under the brand name Fluothane among others, is a general anaesthetic. [5] It can be used to induce or maintain anaesthesia. [5] One of its benefits is that it does not increase the production of saliva, which can be particularly useful in those who are difficult to intubate. [5]
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 .
An example of an ether is the solvent diethyl ether. [1] Halogenated ethers differ from other ethers because there are one or more halogen atoms—fluorine, chlorine, bromine, or iodine—as substituents on the carbon groups. . [2] Examples of commonly used halogenated ethers include isoflurane, sevofluorane and desflurane. [3]
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.
