1

Besides vasodilation both Nipride and nitro have what effects? and why?

Bronchodilator
d/t NO action

2

how does NO (nitric Oxide) cause vasodilation

released from endothelial cells - activates soluble gaudily cyclase (sGC) - converts guanosine triphosphate (GTP) to the 2nd messenger cyclic guanosine monophosphate (cGMP) - cGMP causes smooth muscle dilation (thus both bronchial and vascular)

3

name the action and other name of drug:
Hydralizine

Apresoline
Arterial dilator

4

name the action and other name of drug:
Nitroglycerine

Nitro
Venodilator

5

name the action and other name of drug:
Nitroprusside

Nipride
Arterial and Venous dilator

6

what kind of hypertrophy is IHSS?

Concentric

7

What is the one heart condition unlike all others?

IHSS

8

With IHSS is the myocardial dysfunction caused by anything that the other concentric hypertrophy d/o are from? AKA pressure (HTN)

nope

9

IHSS:
What do you want to do with
HR?
Rhythm?
Preload?
Afterload?
Contractility?

Maintain HR
Sinus
High preload (full)
After load up
decrease contractility

10

how can you remember what worsens and makes IHSS better?

Old Cats Pee Alot
first line increases / 2nd decreases
O increased / increased
C Increased / decreased
P Decreased / Increased
A Decreased / Increased

11

w/ IHSS what may the A-line wave form look like

Bifid (bisferiens pulse)

12

What is an ideal vasopressor for IHSS

Phenyelphrine

13

Valve lesions: AR
what is the anesthetic goals

Fast (increase HR)
Full (increase preload)
Forward (decrease after load)

14

What type of murmur is heard and where at wit AR?

Diastolic
left sternal boarder

15

what pressor and why is good for AR

ephedrine
Forward movement

16

Valve lesions: MR
what you wanna do

Increase HR
decrease after load
normal preload (increase worsens regurg and decrease lowers CO)

17

What do u want to do with HR to all pts with and rugurg

Increase it

18

What do u wanna do with all pts after load with regurg

Decrease it

19

Valve lesions: MR
Chronic MR is d/t what (usually)

Rheumatic fever

20

Valve lesions:AS
what you wanna do

Decrease HR
Keep in NSR
Maiintain preload and afterload

21

What is a good pressor for AS and why?

Phenylephrine
B/c decrease HR

22

what is normal AV area

2.5-3.5 cm2

23

what is the AV for severe AS

0.8-1 cm2

24

what type and where is the murmur heard for AS

Systolic
right 2nd intercostal space

25

when are spinals and epidurals contraindicated w/ AS

when it's severe

26

Valve lesions:MS
what you wanna do

decrease HR (gives more time for LV to fill)
Maintain pre/afterload

27

what type and where is the murmur for MS

diastolic
Apex
