CV stimulation, increased CSF flow, emergence rxns that impair recovery

Question 3

Methohexital

Answer 3

Rapid onset and recovery

Preferred over thiopental for short ambulatory procedures

Question 4

Midazolam

Slow onset and recovery, flumazenil reversal available

Used in balanced anesthesia and conscious sedation, provides CV stability and marked amnesia

Question 5
