Flashcards in IV Anesthetic Deck (21):
1

Propofol effect on SVR?

Decreases SVR

2

Propofol effect on respiratory depression?

Dose dependent reduction

3

Propofol - effect on CBF & ICP?

Decreases CBF & ICP

4

Propofol - PONV?

Decreases PONV but lacks analgesic effects

5

When do you not use propofol?

When you need to avoid peripheral vasodilation - like shock, hypovolemia, aortic stenosis

6

Thiopental - speed of action

Slower offset than propofol esp after repeated doses

7

Thiopental - effect on SVR?

Decreases SVR

8

Thiopental effect on CBF & ICP?

Decreases CBF & ICP

9

Thiopental - effect on respiratory depression?

Dose-dependent respiratory depression

10

Etomidate - speed of action?

Slower offset of action than propofol, rapid onset

11

Etomidate - SVR?

Does not affect SVR, great for use in hypovolemic or hemorrhagic shock

12

Etomidate - side effect?

adrenocortical suppression

13

How does etomidate still cause hypotension?

Through reduction in sympathetic tone

14

Ketamine - side effects?

Causes dissociative anesthesia and unpleasant hallucinations

15

What to give with ketamine to prevent halucinations?

Benzo

16

Ketamine effects on hemodynamics?

Acts as sympathomimetic - increases HR & BP

17

Ketamine effect on CBF & ICP?

Increases CBF & ICP

18

Does ketamine have analgesic properties?

Yes

19

When to avoid ketamine?

Increased ICP, ruptured globe, anything at risk for coronary ischemia

20

When to use ketamine?

Hemorrhagic or hypovolemic shock but it can result in hypotension in situations where endogenous sympathetic reserve is depleted

21

Ketamine - effect on respiratory drive?

Supports respiratory drive
