 # Which of the following inhalational anesthetic has analgesic property?
A. Nitrous oxide
B. Halothane
C. Enflurane
D. Sevoflurane



The correct answer is A. Nitrous oxide

The use of nitrous oxide to relieve the pain of surgery was suggested by Humphrey Davy in 1800. He was the first person to make nitrous oxide, and he tested its effects on several people, including himself and the Prime Minister, noting that it caused euphoria, analgesia and loss of consciousness. The use of nitrous oxide, billed as ‘laughing gas’, became a popular fairground entertainment and came to the notice of an American dentist, Horace Wells, who had a tooth extracted under its influence, while he himself squeezed the inhalation bag.
