Gases Flashcards
1
Q
What is the most potent volatile anesthetic?
A
Isoflurane
2
Q
The gold standard to measure potency is:
A
MAC
3
Q
Which volatile anesthetic causes the greatest degree of coronary vasodilation?
A
Isoflurane, but this hasn’t shown any clinical difference
4
Q
How does solubility impact potency?
A
The higher the solubility → the lower the MAC → the higher the potency
5
Q
Which anesthetic may be ideal in obese patients?
A
Des
Its fat solubility is half that of the other gases
6
Q
If Des has increased MAC/decreased potency because it has a Fl atom instead of a Cl atom, why does Sevo (which is fully flourinated) have a higher MAC and higher potency than Des?
A
Because it has a bulky propyl side chain on the ether molecule
