Final answer:
Isoflurane, sevoflurane, and desflurane are inhalational anesthetics that augment neuromuscular blockade, unlike nitrous oxide which does not have this property significantly.
Step-by-step explanation:
Inhalational agents are commonly used in the administration of general anesthesia. Among them, isoflurane, sevoflurane, and desflurane are notable for their ability to augment neuromuscular blockade, which is an important aspect for surgeries that require muscle relaxation.
These agents are fluorinated ethers, widely preferred in modern anesthetic practice due to their safety profile and effectiveness. Contrarily, nitrous oxide, while often used in conjunction with other inhalational anesthetics to enhance their effects, does not significantly augment neuromuscular blockade.
