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 .
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.
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 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. [ 17 ]
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]
A relative analgesia machine is used by dentists to induce inhalation sedation in their patients. It delivers a mixture of nitrous oxide ("laughing gas") and oxygen.A relative analgesia machine is simpler than an anaesthetic machine, as it does not feature the additional medical ventilator and anaesthetic vaporiser, which are only needed for administration of general anesthetics.
It can be used to start or maintain anesthesia; however, other medications are often used to start anesthesia, due to airway irritation with isoflurane. [3] [5] Isoflurane is given via inhalation. [4] Side effects of isoflurane include a decreased ability to breathe (respiratory depression), low blood pressure, and an irregular heartbeat. [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.
