− | '''Inhalation anaesthetics''' are commonly used after induction with [[Injectable Agents|injectable agents]] but can also themselves be used for the induction of anaesthesia. However, inhalation agents are poor analgesics and have varying muscle relaxant ability. As expected, if used alone, much higher concentrations of inhalation agents are required to produce general anaesthesia then if used in combinations with analgesics and/or muscle relaxants - a '''balanced anaesthetic technique''''. They are unusual in respect to most other drugs, as they are adminstered and removed via the same route i.e. as the patient breathes. This also allows for easy adjustment to the depth of anaesthetic of a patient as it does not rely on the metabolism of the agent. | + | '''Inhalation anaesthetics''' are commonly used after induction with [[Injectable Agents|injectable agents]] but can also themselves be used for the induction of anaesthesia.
