Dopamine ROSC infusion
400 mg in 250 ml bag
COH 1600 mcg/ml
2-20 mcg/kg/min (start @5 and titrate)
Epi ROSC infusion
1mg 1:1,000 in 250 ml bag
COH 4 mcg/ml
0.1-0.5 mcg/kg/min
Norepi ROSC infusion
Use infusion pump
4 mg in 250 ml bag
COH 16 mcg/ml
0.1-0.5 mcg/kg/min
Atropine
indications/dose
Hemodynamically significant bradycardia
0.5 mg IVP q 3-5 min
Max 3 mg
If failed, TCP then Dopamine or Epi infusions
Epi
Hemodynamically significant Brady dose
2-10 mcg/min
COH 4 mcg/ml (lower than ROSC dose)
Epi
drug class and MOA
Sympathetic agonist
Alpha effects for ROSC (vesoconstrict and send more blood to heart)
Beta effects for bradycardia (raise HR)
Positive chronotrope, inotrope, dromotrope, vesoconstrict, higher automaticity
Norepi
drug class and MOA
Mostly alpha, some beta
Some Inotropic (heart squeeze harder)
Dilate coronary vessels
Dopamine
drug class and MOA
Raise BP via alpha and beta
Positive inotropic (for cardiac shock/pump failure)
Indications: brady, cardiogenic shock, hypotension
Metoprolol
drug class and MOA
Beta blocker
More B1 and lower HR, lower systolic,
Lower cardiac output, inhibits tachy
Lidocaine
drug class and MOA
For ventricular dysrhythmias
Vtach/vfib w pulse, AMI, runs of PVC
Adenosine
drug class and MOA
Works on slowing AV node for SVT
CAUTION: up to 6 sec of asystole after push
Diltiazem
drug class and MOA
Calcium channel blocker
Slows afib/flutter (won’t covert), SVT after adenosine
Slows HR, lower contractility, vasodilator
Antidote: Calcium chloride
Never give w beta blocker or WPW
Amiodarone MOA
Blocks everything, bad/fast vent. rhythms (vtach/vfib), sometimes bad/fast atrial rhythms
Slows action potential, delays Repolarization
Amiodarone contraindications
Pregnancy
Slow rhythms
Iodine/shellfish allergy
Heart failure
Mag sulfate MOA/ind/antidote
Calcium channel blocker (can be antidote for calcium)
Torsades de point
Can cause respiratory depressions/arrest (calcium counteracts)
