|
Adenosine
|
Dosage and Delivery
6mg by rapid IV push, followed by 10-20ml of normal saline solution (NSS); May repeat a 12 mg dose twice, followed by NSS flush Indication tachycardia Action Depresses sinoatrial and atrioventricular node activity, slowing the heart rate Nursing Implications -Know that the drug causes brief period of asystole. Monitor for underlying atrial activity during this time. -Be aware that drug trigger facial flushing. -may cause sinus bradycardia, dyspnea, hypotension |
|
|
Amiodarone
|
Dosage and Delivery
150 mg bolus given IV over 10 minutes, followed by continuous IV infusion at 1 mg/minute for 6 hours, then 0.5 mg /minute for 18 hours Indication tachycardia Action Reduces the heart rate Nursing Implications -Know that the drug has a long half life (28-110 days), rarely affects blood pressure, and may cause bradycardia or heart failure. -Monitor for drug allergy or reaction. Pulmonary toxicity (dyspnea, cough, chest pain), corneal microdeposits (photophobia, blurred vision) |
|
|
Atenolol, metoprolol
|
Dosage and Delivery
5 mg IV bolus over 5 minutes; may repeat atenolol dose once and metoprolol dose twice Indications tachycardia action Reduce catecholamines, leading to slower heart rate and lower blood pressure nursing implications -Monitor for bradycardia and/or pauses in heart rhythm. -Monitor blood pressure for hypotension. |
|
|
Atropine
|
Dosage and Delivery--NEED TO KNOW
0.5 to 1 mg by IV push. Max amount is 3mg. Indication Bradycardia, not effective in CHB Action Increases the heart rate through anticholinergic effect Nursing Implications -Be aware that dosages below 0.5 mg may further slow the heart rate. -Monitor for rebound tachycardia. -Monitor blood pressure for improvement. |
|
|
Diltiazem
(Cardizem) |
Dosage and Delivery
5 to 20 mg by IV push over 2-5 minutes, followed by IV infusion or additional 20-25 mg by IV push after 15 minutes Indication Atrial tachycardias Action Lengthens cardiac cycle, slowing the heart rate Nursing Implications -Titrate dosage in small increments to achieve desired heart rate. -Begin oral drugs before stopping infusion, unless severe. - Monitor for bradycardia, pauses in heart rhythm, and/or ↓ BP, heart failure & AV block. |
|
|
Dopamine
|
Dosage and Delivery
5 to 15 mcg/kg/minute by IV infusion Indication Bradycardia, hypotension Action Stimulates the dopamine receptors and increases cardiac output, with minimal increase in oxygen consumption; causes peripheral vasoconstriction Nursing Implications -Monitor for rebound tachycardia and/or hypertension. -Monitor blood pressure for improvement. -Titrate dosage in small increments to desired effect. -If possible, deliver via central line. |
|
|
Epinephrine
|
Dosage and Delivery
1mg Q 3-5 minutes, 2 to 10 mcg/min by IV infusion Indication Pulseless rhythms, Bradycardia Action Stimulates beta1 receptors, causing cardiac stimulation Nursing Implications -Monitor for rebound tachycardia and/or hypertension. -Monitor blood pressure for improvement. -If possible, deliver via central line. |
|
|
Lidocaine
|
Dosage and Delivery
1mg/kg IV bolus then infusion of 1-4 mg/min Indication Ventricular dysrhythmias Action Slows conduction, reduces automaticity, accerlates repolarization Nursing Implications -CNS effects with high doses (drowsiness, confusion, paresthesias → convulsions, resp. arrest) |
|
|
Vasopressin
|
Dosage and Delivery
40 units IV bolus one time Indication Ventricular dysrhythmias Action Return rhythm & pulse, potent vasoconstrictor Nursing Implications Equal to epinephrine Long half life |
