Final answer:
Halothane is the inhaled anesthetic associated with causing massive hepatic necrosis, a serious condition which can lead to severe liver damage and is life-threatening.
Step-by-step explanation:
The inhaled anesthetic known to result in massive hepatic necrosis is halothane. Halothane is a fluorine-containing compound that has been used as an inhalational anesthetic. While it is effective in producing anesthesia, halothane has been associated with severe liver damage, particularly massive hepatic necrosis, which can be a life-threatening condition. This adverse effect is particularly concerning as it can occur after exposure to halothane, even with modern monitoring and support. Anesthetics like halothane are administered by inhalation, and they act by entering the bloodstream through the lungs.
The mode of administration of anesthetics such as halothane involves the use of gases or vapors to maintain anesthesia after induction, often initially with an intravenous agent. It is important to note that halothane usage has decreased due to its potential for liver toxicity and alternative inhalational anesthetics like enflurane and isoflurane have become more widely used, as they have better safety profiles regarding hepatic effects.
