Q

when to use vasopressors

A

MAP < 60 mmHg or SBP drop 30+ mmHg from baseline when causing end-organ dysfunction related to hypoperfusion- at this point would use vasopressors

Q

use for vasopressin

A

vasopressin 1 used for septic shock - only in addition to norepi this is always a second or 3rd line add on

Q

name my T causes for cardiac arrest

A
toxins
tamponade
tension pneumothorax
thrombosis (mi or pe)
also kinda trauma- but mostly from the hypovolemia side of bleeding

16
Q

indications for pharmacologic cardioversion

A

SVT, v-tach with pulse, afib, torsades

17
Q

contraindications for pharmacologic cardioversion

A

-unstable (nausea, poor mentation, SBP <90, chest pain, SOB)

a-fib longer than 48 hrs or unknown duration (need anticoagulation before converting)

18
Q

adenosine PC

A

only in monomorphic tach (no fib or flutter) if not successful pharm cardioversion may slow rate down enough to determine rhythm

19
Q

amiodarone PC

A

not for a fib if duration over 48 hrs

can convert svt v tach or afib

20
Q

digoxin PC

A

rate control good for a fib regardless of coag

also for svt

21
Q

dofetilide

A

1c class- na channels and effects phase 0
must recheck QTc 2-3 hours and remain in patient for 3 days
afib/flutter

22
Q

metoprolol tartrate

A

goof for svt and a fib

*not good for sinus tach- this is compensatory so slow down heart got a big prob

23
Q

CHF diuretics

A

almost all patients start a loop
if poor renal function will need hig doses but monitor K and Mg
*if not enough can add a thiazide or spirolactone but caution K sparing of Spirolactone

24
Q

Bblockers to use for CHF

A

Bisoprolol carvedilol metroprolol sucsinate

25
Q

Adequate end organ perfusion AND hypertension or mitral or aortic valve regurgitation

A

nitroprusside

26
Q

Adequate end organ perfusion AND inadequate response to diuretics (no longer than 15-30 mins in sick patients):

A

nitroglycerin to reduce preload

27
Q

Known systolic HF (low EF) with cardiogenic shock

A

stop bblocker and give inotrope (dobutamine) and mechanical heart support

28
Q

loops dose IV to home

A

2 mg home to 1 mg iv

29
Q

after digoxin od

A

give digoxin immune fab and monitor ecg and serum K
