Flashcards in Volatile anesthetics Deck (13):
How are volatile anesthetic doses expressed?
In percent concentration of inhaled gas
How do all volatiles effect SVR & myocardial function?
Vasodilation & myocardial depression
The most hemodynamically stable pharmacodynamics?
Longest on/off but fewest cardiac side effects and least expensive, good for long cases
Shortest on/off but airway irritant
Causes the least airway irritation and can be used for induction of anesthesia
Nitrous Oxide - when to avoid?
Readily diffuses into closed air spaces. Should be avoided in situations where an increase in volume of pressure of an enclosed space is undesired - i.e. middle ear surgery, bowel obstruction, pneumothorax
Partial pressure of inhaled anesthetic which prevents movement in response to surgical incision in 50% of the population
Factors that affect MAC
Potency, age, concurrent drug administration, ethanol or illicit substance use, pregnancy
