If you’ve ever had to undergo a surgical procedure, be it at the dentists or in a hospital, you’re likely to have encountered some of the molecules featured in today’s graphic. We’re already looked at inhalational anaesthetics in a previous graphic; today, we take a look at chemicals that can be injected in order to produce anaesthesia.
If you’ve ever needed a tooth out, or had surgery of any kind, chances are you’ll have experienced use of an inhalational anaesthetic. All of the compounds shown above can induce general anaesthesia, and a range have been utilised since the initial discovery of nitrous oxide in the mid-1800s. Often, intravenous drugs will be used for induction of anaesthesia, but inhalational agents may then be used to maintain this – this graphic looks at how the drugs in use for this purpose have varied over the years.
