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 .
Such substances are also called inhalational, e.g. inhalational anesthetics. Intra-arterial (into an artery), e.g. vasodilator drugs in the treatment of vasospasm and thrombolytic drugs for treatment of embolism. Intra-articular, into a joint space. It is generally performed by joint injection. It is mainly used for symptomatic relief in ...
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 purpose of anesthesia can be distilled down to three basic goals or endpoints: [2]: 236 hypnosis (a temporary loss of consciousness and with it a loss of memory.In a pharmacological context, the word hypnosis usually has this technical meaning, in contrast to its more familiar lay or psychological meaning of an altered state of consciousness not necessarily caused by drugs—see hypnosis).
Inhalational anaesthesia may be chosen when intravenous access is difficult to obtain (e.g., children), when difficulty maintaining the airway is anticipated, or when the patient prefers it. Sevoflurane is the most commonly used agent for inhalational induction, because it is less irritating to the tracheobronchial tree than other agents. [37]

Leaves of the coca plant (Erythroxylum novogranatense var. Novogranatense), from which cocaine, a naturally occurring local anesthetic, is derived [1] [2].
