Final answer:
Hepatitis induced by volatile anesthetics is rare, with an incidence of about 1 in 50,000. This is mainly associated with halothane, but other newer anesthetics also pose a very low risk of hepatitis.
Step-by-step explanation:
The incidence of hepatitis induced by volatile anesthetics is considered to be a rare event. The correct answer to the question is d) 1 in 50,000. This type of hepatitis is often associated with halothane, a volatile anesthetic that has been linked to cases of halothane hepatitis—a rare but serious complication that can occur after exposure to halothane. Other volatile anesthetics, such as enflurane, isoflurane, sevoflurane, and desflurane, have since replaced halothane in many practices primarily due to their lower risk of inducing hepatitis. Nevertheless, the risk of hepatitis with these newer agents is also very low, contributing to their widespread use in modern anesthesia.
