in cardiac arrest when do you first introduce medical intervention? which drug?
answer
after 2 rounds of CPR/shock
after 2nd shock give 1 mg epinephrine every 3-5 minutes
question
when do you introduce amiodarone during cardiac arrest?
answer
after the 3rd shock give 300 mg bolus of amiodarone
if second dose is needed give 150mg as second dose
question
what rhythms are shockable in cardiac arrest
answer
VF
VT
question
what rhythms are not shockable in cardiac arrest
answer
asystole
PEA
question
if you are in an unshockable rhythm arrest when do you give epi
answer
1mg epi every 3-5 minutes after 1st round of CPR
question
what do you do after return of spontaneous circulation
answer
maintain O2 sat at 94%
treat hypotension (fluids vasopressor)
12 lead EKG
if in coma consider hypothermia
if not in coma and ekg shows STEMI or AMI consider re-perfusion
question
what are the 5 h's and 5 t's
answer
hypovolemia
hypoxia
hydrogen ion (acidosis)
hypo/hyperkalemia
hypothermia
tension pneumothorax
tamponade, cardiac
toxins
thrombosis, pulmonary
thrombosis, coronary
question
how do you treat non-symptomatic bradycardia
answer
monitor and observe
question
what constitutes symptomatic bradycardia
answer
hypotension
altered mental status
signs of shock
chest pain
acute heart failure
question
how do you treat symptomatic bradycardia
answer
1. give 0.5mg atropine every 3-5 mins to max of 3mg
if that doesn't work try one of the following:
transcutaneous pacing
2-10mcg/kg / minute dopamine infusion
2-10mcg/minute epinephrine infusion
question
what is considered a tachycardia requiring treatment
answer
over 150 per minute
question
when do you consider cardioversion
answer
if persistent tachycardia is causing:
hypotension
altered mental status
signs of shock
chest pain
acute heart failure
question
if persistent tachycardia does not present with symptoms what do you need to consider
answer
wide QRS?
greater than 0.12 seconds
question
If persistent tachycardia without symptoms DOES have a wide QRS what to do you do?
answer
IV access and 12 lead if available
6mg adenosine followed by NS flush only IF regular and monomorphic
consider anti-arrhythmic infusion:
- 20-50mg/min procainamide (max 17mg/kg)
- 150mg amiodarone over 10 minutes
- 100mg sotalol over 5 minutes
question
which anti-arrhythmic drugs can be used if prolonged QT
answer
only amiodarone
150mg over 10 minutes, repeat if VT occurs
follow by maintenance infusion 1mg/min for first 6 hours
question
if persistent tachycardia without symptoms and without wide QRS what do you do
answer
IV access and 12 lead EKG if available
vagal maneuvers
6mg adenosine followed by NS flush only IF regular
Beta blocker or calcium channel blocker
question
patient comes in with symptoms of ACS what do you do first
answer
chew 325mg aspirin
O2
nitro
morphine
get 12 lead EKG
IV access
question
IF ACS patient has EKG showing ST elevation and symptoms are less than 12 hours then what
answer
re-perfusion
door to balloon 90 minutes
door to needle 30 minutes
question
If ACS patient has EKG showing non ST elevation MI or high risk unstable angina then what
answer
early invasive strategy?
adjunctive treatment?
-nitroglycerin
-heparin
-beta blockers
-clopidogrel
-glycoprotein IIb / IIIa inhibitor
question
what are the contraindications to fibrinolytics in ACS treatment
answer
systolic > 180
diastolic > 100
right arm left arm systolic difference > 15
history of structural central nervous system disease
recent head/facial trauma
stroke more than 3 hours or less then 3 months ago
recent trauma, surgery or bleed
any history of intracranial hemorrhage
bleeding, clotting problem or on blood thinners
serious systemic disease
question
adenosine
answer
used in tachy
6mg bolus followed by 20mL normal saline
12mg can be used after 1-2 minutes
question
amiodirone
answer
In VF/VT arrest AFTER trying CPR shock and epi/vasopressin:
300mg then 150mg
In life threatening arrhythmias:
150mg over 10 minute infusion, every 10 minutes as needed
question
atropine sulfate
answer
use as first line defense in sinus bradycardia
0.5mg every 3-5 minutes as needed MAX is 3mg ( think alive gets 0.5)
do not use if hypothermia
question
dopamine
answer
2nd line drug for symptomatic bradycardia
use for hypotension with signs of shock
2-20 mcg/kg per minute
question
epinephrine
answer
in cardiac arrest:
1mg every 3-5 minutes
in bradycardia or hypotension:
2-10mcg/minute infusion
question
lidocaine
answer
alternative to amiodirone in cardiac arrest:
1-1.5 mg/kg IV
for stable VT, wide complex VT:
0.5 - 0.75 mg.kg every 5-10 minutes max of 3mg/kg
question
magnesium sulfate
answer
use in cardiac arrest only if hypomagnesemia or torsades:
1-2g diluted in 10mL of D5W
use in torsades with a pulse or AMI with hypomagnesia:
1-2g in 50 to 100 mL of D5W
maintenance with 0.5g per hour infusion
