Nitrous oxide: which statement is true?

Nitrous oxide: which statement is true?

• A. It is always administered by an anesthetic machine
• B. It is a muscle relaxant and has analgesic properties
• C. It can be used in combination with isoflurane
• D. All of the above

Answer: (C)

Nitrous oxide is an inhaled agent used as an adjunct to other anesthetics. It provides some analgesia and helps reduce the amount of a volatile agent needed to reach the desired depth of anesthesia—this is the MAC-sparing effect. In practice, it is commonly used in combination with a volatile anesthetic like isoflurane to achieve effective anesthesia while using lower concentrations of each agent. It is not a muscle relaxant, and its analgesic effect is present but not strong enough to rely on alone for pain control. It can be delivered through various delivery setups, not exclusively through a dedicated anesthetic machine. So the statement that it can be used in combination with isoflurane is true.
