pharm CHF Flashcards
inotropes
increase cardiac contractility
vasopressors
increase MAP
when to use vasopressors
MAP < 60 mmHg or SBP drop 30+ mmHg from baseline when causing end-organ dysfunction related to hypoperfusion- at this point would use vasopressors
risk of vasopressors
decreased perfusion to peripheral tissues, risk of necrosis if administered via peripheral vein
use for Phenylephrine
increase systemic vascular resistant anesthesia induced hypotension
use for norepinephrine
alpha 1 and beta 1 increase MAP and CO septic shock
use for epinephrine
alpha 1 beta 1 and 2 anaphylactic shock
use for vasopressin
vasopressin 1 used for septic shock - only in addition to norepi this is always a second or 3rd line add on
name my H causes for cardiac arrest
hypovolemia hypoxia hydrogen ion (acidosis) hyper/hypo kalemia hypothermia also kind hypoglycemia
name my T causes for cardiac arrest
toxins tamponade tension pneumothorax thrombosis (mi or pe) also kinda trauma- but mostly from the hypovolemia side of bleeding
v-fib no pulse
epinephrine (push very 3-5 min)
amiodarone
lidocaine
mag sulfate for torsades de pointes
PAE/asystole
epinephrine
bradycardia with pulse
atropine
epi
dopamine
tachycardia with pulse regular monomophic
give adenosine then saline
tachycardia with pulse
synchronized cardioversion amiodarone diltiazem sotalol digoxin verapamil
indications for pharmacologic cardioversion
SVT, v-tach with pulse, afib, torsades
contraindications for pharmacologic cardioversion
-unstable (nausea, poor mentation, SBP <90, chest pain, SOB)
a-fib longer than 48 hrs or unknown duration (need anticoagulation before converting)
adenosine PC
only in monomorphic tach (no fib or flutter) if not successful pharm cardioversion may slow rate down enough to determine rhythm
amiodarone PC
not for a fib if duration over 48 hrs
can convert svt v tach or afib
digoxin PC
rate control good for a fib regardless of coag
also for svt
dofetilide
1c class- na channels and effects phase 0
must recheck QTc 2-3 hours and remain in patient for 3 days
afib/flutter
metoprolol tartrate
goof for svt and a fib
*not good for sinus tach- this is compensatory so slow down heart got a big prob
CHF diuretics
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
Bblockers to use for CHF
Bisoprolol carvedilol metroprolol sucsinate
