Anesthesia - Nitrous Oxide

pain british anesthetic chemist

In 1776 Joseph Priestley, a British chemist, discovered the gas nitrous oxide. Another British chemist, Humphry Davy, proposed nitrous oxide as a means for pain-free surgery, but his views were dismissed by other physicians of the day. In the next century, Horace Wells, a Connecticut dentist, began to experiment with nitrous oxide, and in 1845 attempted to demonstrate its anesthetic qualities to a public audience. However, the patient woke before the operation was over and began to scream in pain. Because of this spectacle, it took another 20 years before nitrous oxide again gained attention. By 1870, nitrous oxide was a commonplace dental anesthetic.
