Steep curves and narrow therapeutic indices
How can depth of anesthesia be rapidly altered with inhaled gases?
By altering the inhaled concentration
How do IV anesthetics cause rapid induction?
By traveling from arm to brain quickly
What is the mechanism of recovery from IV anesthetics?
Redistribution within the CNS
What is the role of IV anesthetics during longer procedures?
To maintain anesthesia with inhaled agents
In lower doses, IV anesthetics may be used for:

What are the five primary effects characterized by the neurophysiologic state produced by general anesthetics?
Unconsciousness, amnesia, analgesia, inhibition of autonomic reflexes, muscle relaxation
Which route is commonly used to administer general anesthetics?
Orally
What is the main goal of an ideal anesthetic drug?

Which type of anesthesia involves unconsciousness, analgesia, amnesia, skeletal muscle relaxation, and loss of reflexes?
General anesthesia
Why is it challenging for a single anesthetic agent to achieve all five desired effects of general anesthesia well?
Anesthetic agents have limitations in targeting specific receptors
