Diethyl ether as an inhalant anesthetic is characterized by which of the following?

Diethyl ether as an inhalant anesthetic is characterized by which of the following?

• A. Low margin of safety and highly flammable
• B. High margin of safety and non-flammable
• C. No irritant and non-noxious
• D. Not used as an inhalant anesthetic

Answer: (A)

The key idea is understanding the safety and flammability characteristics of diethyl ether used as an inhaled anesthetic. Ether has a narrow safety margin, meaning the range between the dose that produces anesthesia and doses that can cause dangerous depression of breathing or heart function is small. This requires very careful monitoring and control of its administration. At the same time, ether vapors are highly flammable and can form explosive mixtures, which created serious fire hazards in the past and remain a major contention in its use. It does have irritant effects and can cause nausea and mucous membrane irritation, so it is not accurate to label it as having no irritant or noxious effects. Although it has been used historically as an inhaled anesthetic, it is not commonly used today because of these safety concerns. Therefore, the description of a low margin of safety paired with high flammability best fits diethyl ether.
