-
Adenosine Class
Endogenous Nucleotide
-
Phenytoin Class
Anticonvulsant, antiarrhythmic.
-
Labetalol Class
Betablocker.
-
Calcium Chloride Class
Electrolyte.
-
Norepinephrine Class
Vasopressor, alpha/beta agonist.
-
Adenosine MOA
Slows conduction time through the AV node. Slows heart rate. Acts directly on sinus pacemaker cells.
-
Norepinephrine MOA
Peripheral vasoconstrictor of arterial/venous beds.
-
Phenytoin MOA
Inhibits the spread of seizure acitivity through motor cortex.
-
Labetalol MOA
Selectively blocks a1 receptors and nonselectively blocks B receptors.
-
Calcium Chloride MOA
Increases cardiac contractile (and inotropic effect). May enhance ventricular automaticity.
-
Calcium Chloride Indications
Hypocalcemia, magnesium sulfate OD, hyperkalemia, tx of insect bites.
-
Labetalol Indications
Hypertensive crisis.
-
Phenytoin Indications
Status epilecticus, arrhythmias due to digitalis toxicity.
-
Norepinephrine Indications
Shock, hypotension.
-
Adenosine Indications
Conversion of PSVT to sinus rhythm.
-
Adenosine Contraindications
2nd or 3rd degree block or Sick Sinus Syndrome. Afib, Aflutter, Vtach.
-
Norepinephrine Contraindications
Hypotension due to hypovolemia.
-
Phenytoin Contraindications
Any arrhythmia except those due to digitalis toxicity.
-
Labetalol Contraindications
Bronchial asthma, CHF, heart block, bradycardia, cardiogenic shock.
-
Calcium Chloride Contraindications
Hypercalcemia, VF during cardiac resuscitation, digitalis toxicity.
-
Calcium Chloride Dose
2-4 mg/kg of a 10% solution every 10 minutes.
-
Labetalol Dose
20 mg slow IV with 40-80 mg every 10 minutes as needed up to 300 mg total. Or 2 mg/min continous infusion up to 300 mg total dose.
-
Phenytoin Dose
10-15 mg/kg slow IV.
-
Norepinephrine Dose
0.5-30 mcg/min IV infusion.
-
Adenosine Dose
6 mg IVP followed by 20-30 cc NS flush, may repeat in 1-2 minutes with 12mg IVP followed by 20-30 cc NS flush, may repeat one more time at 12 mg IVP followed by 20-30 cc NS flush.
