B) Midazolam (Generic)

D) Propofol (Diprivan)
C
Feedback:
Ketamine has been associated with a bizarre state of unconsciousness in which the patient appears to be awake but is unconscious and cannot feel pain. This drug, which causes sympathetic stimulation with increase in blood pressure and heart rate, may be helpful in situations when cardiac depression is dangerous. Thiopental is a barbiturate anesthetic. Midazolam and propofol are nonbarbiturate anesthetics. None of these medications have this type of effect.
