Final answer:
Rocuronium and vecuronium are NDMR aminosteroid compounds used to aid in intubation, muscle relaxation, and mechanical ventilation during anesthesia.
Step-by-step explanation:
The NDMR (non-depolarizing muscle relaxants) that are aminosteroid compounds include rocuronium and vecuronium. These are synthetic steroids used in anesthesia to facilitate tracheal intubation, provide skeletal muscle relaxation, and to aid in mechanical ventilation. They work by competing with acetylcholine at the nicotinic receptors at the neuromuscular junction, which inhibits the transmission of nerve impulses to muscles.
