Sevoflurane in the context of General anesthesia

Halothane (Bromochlorotrifluoroethane), sold under the brand name Fluothane among others, is a halocarbon with the chemical formula CF₃CHBrCl. It is used as a general anaesthetic given by inhalation. It can be used to induce or maintain anaesthesia. Its use in developed countries has been mostly replaced by newer anesthetic agents such as sevoflurane. 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.

Side effects include an irregular heartbeat, respiratory depression, and hepatotoxicity. Like all volatile anesthetics, it should not be used in people with a personal or family history of malignant hyperthermia. It appears to be safe in porphyria. It is unclear whether its usage during pregnancy is harmful to the fetus, and its use during a C-section is generally discouraged. Halothane is a chiral molecule that is used as a racemic mixture.

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. Agents of significant contemporary clinical interest include volatile anesthetic agents such as isoflurane, sevoflurane and desflurane, as well as certain anesthetic gases such as nitrous oxide and xenon.
