What is the useful difference between propofol, ketamine, and etomidate?

All three can be used as induction anesthetics (that is, for inducing sedation), but only propofol can be used to maintain anesthesia.

What is the mechanism of propofol and etomidate?

They – like benzodiazepines, barbiturates, alcohol, and the non-sedative hypnotics – activate the GABA-A receptor. (Think of the old-fashioned Caba cab.)

The most important side effect of propofol is ____________.

"profound" vasodilation (think of the hypnotist's sleeves); this can induce tachycardia

The main benefit of etomidate is _____________.

absence of cardiac side effects – specifically, etomidate does not cause vasodilation (think of the Intimidator balancing the hypnotized person)

What are the side effects of ketamine?

Dissociative state (eyes open, but unconscious); unpleasant hallucinations; increased cardiac output (the heart-shaped cobra hood)
