There are many inhalational anaesthetic agents. These include:
- Sevoflurane
- Methoxlyflurane
- Halothane
- Isoflurane
- Enflurane
- Ether
- Desflurane
Modern anaesthetic agents are very potent. All are liquids at room temperature and vaporise readily, so they must be delivered using a purpose-made vaporiser. The concentration of anaesthetic needed to induce and maintain anaesthesia varies between the different agents.
