|Good afternoon ladies and
gentlemen, my name is ________ and today Iím going to have a look at the
anaesthetic agent nitrous oxide, which was first synthesised by Joseph
Priestly, an English natural philosopher, over 200 years ago.† It is the only anaesthetic agent from the
19th century that survives into modern usage and has been used
clinically in anaesthesia for over 150 years.
|Iíll look first at how
this agent came to be used as an anaesthetic following the years of its
discovery.† I then want to look at its
use in the 20th and 21st centuries.† Nitrous oxide has in recent years been
called outdated Ė what are the indications for the continued use of this
agent, and what are its prospects in the future of anaesthetic practice?
