Which of the following is a common inhalational anesthetic agent?

Sevoflurane is a well-known inhalational anesthetic agent commonly used in both adult and pediatric anesthesia. It belongs to a class of anesthetics that are administered via inhalation, allowing for rapid induction and emergence from anesthesia. Sevoflurane is favored for its pleasant odor, making it easier for patients, especially children, to tolerate mask induction. It provides a smooth and effective anesthetic experience and is widely used in various surgical procedures.

Inhalational anesthetics like sevoflurane generally function by causing dose-dependent effects on the central nervous system, allowing for the depression of consciousness and pain perception necessary for surgery. The pharmacokinetics of inhalational agents, such as sevoflurane, involve the delivery of the agent through a vaporizer where it is mixed with oxygen, allowing for controlled administration and adjustment of the depth of anesthesia during the procedure.

Other agents listed, such as propofol and dexmedetomidine, are not classified as inhalational anesthetics; instead, they are intravenous agents. Fentanyl is an opioid analgesic used for pain management rather than a primary anesthetic agent. Thus, sevoflurane is recognized distinctly for its effectiveness as an inhalational anesthetic
