Nitrous oxide, sometimes informally referred to as laughing gas, has historically been used in medical and dental settings for what purpose?

Explanation

Nitrous oxide, sometimes informally called laughing gas, has long been used in medical and dental settings as a mild anesthetic, typically inhaled to help reduce pain sensitivity and anxiety during certain minor procedures, while allowing the patient to remain conscious throughout. Its relatively mild, short-acting effects and generally favorable safety profile compared to some other anesthetic options have contributed to its continued use, particularly in dental practices. Nitrous oxide was also notably one of the earliest substances used for anesthesia in the history of modern medicine. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
