An inhalational anesthetic is a chemical compound possessing general anesthetic properties that is delivered via inhalation. They are administered through a face mask, laryngeal mask airway or tracheal tube connected to an anesthetic vaporiser and an anesthetic delivery system .
Nitrous oxide, as medical gas supply, is an inhaled gas used as pain medication, and is typically administered with 50% oxygen mix. It is often used together with other medications for anesthesia. [2] Common uses include during childbirth, following trauma, and as part of end-of-life care. [2]
Sevoflurane, sold under the brand name Sevorane, among others, is a sweet-smelling, nonflammable, highly fluorinated methyl isopropyl ether used as an inhalational anaesthetic for induction and maintenance of general anesthesia. After desflurane, it is the volatile anesthetic with the fastest onset. [8]
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]
Inhalation sedation using nitrous oxide has a long history of safe use in both medicine and dentistry. It can therefore be used safely in most patients in the dental setting. [5] However, in some patients sedation with nitrous oxide would be unsuitable. Some examples are below. A patient who is unable to use a nasal mask.
General anaesthetics can be administered either as gases or vapours (inhalational anaesthetics), or as injections (intravenous or even intramuscular).All of these agents share the property of being quite hydrophobic (i.e., as liquids, they are not freely miscible—or mixable—in water, and as gases they dissolve in oils better than in water).
The Consumer Healthcare Products Association, a group that represents over-the-counter drug manufacturers, said it is against removing oral phenylephrine from the market, adding that it is the ...
The 1990s saw the development of sevoflurane, which was especially helpful in pediatric anesthesia because it provided even faster induction and recovery profiles. [7] All inhalation anesthetics in current clinical use are halogenated ethers, except for halothane (which is a halogenated hydrocarbon or haloalkane), nitrous oxide, and xenon. [8]
