Cardiac Drugs Flashcards
Adenosine trade name?
Adenocard
Adenosine classification?
Antiarrhythmic
Adenosine actions?
Decrease electrical conduction through the AV node
Adenosine onset/duration?
Immediate / 10 seconds (half-life)
Adenosine indications?
SVT, WPW. May administer to VTach with a pulse if it does not convert with Amiodarone administration (SVT with aberrancy)
Adenosine contraindications?
Drug-induced tachycardia, second or third-degree AV block, hypersensitivity, A-Flutter, A-fib, VTach (unless SVT with aberrancy), WPW with A-fib or A-flutter
Adenosine side effects?
Facial flushing, light headedness, paresthesia, headache, diaphoresis, palpitations, chest pain, flushing, feeling of impending death or passing out, hypotension, SOB; transient periods of bradycardia, sinus pause, asystole; ventricular ectopy, nausea, metallic taste.
These side effects are usually limited due to short half-life of this drug.
Adenosine route of admin?
Rapid IV push- followed by a 10-20mL saline flush
Adenosine adult dose?
6mg rapid IV push given over 1-3 seconds. May repeat within 1-2 minutes at 12mg if needed
Adenosine peds dose?
0.1 mg/kg (max 6mg) rapid IV and IO followed by a 5-10mL saline flush. May repeat within 2 minutes at 0.2 mg/kg (max 12mg)
Adenosine supply?
3mg/mL in 2mL vials
prefilled syringes
Adenosine special considerations?
Pts taking theophylline or caffeine may require larger doses
Amiodarone trade name?
Cordarone
Amiodarone classification?
Class 3 Antidysrhythmic
Amiodarone actions?
Blocks sodium, potassium, and calcium channels of the cardiac conduction cycle that slows conduction and prolongs the refractoriness of the heart
Amiodarone onset/duration?
within minutes / variable
Amiodarone indications?
Vfib and pulseless VTach, VTach with a pulse, and some atrial dysrhythmias
Amiodarone contraindications?
None in pulseless cardiac events.
Pts with predisposing history of bradycardia or AV node block, hypotension, hyperkalemia, and cardiogenic shock
Amiodarone side effects?
Hypotension, prolonged QT interval, Dizziness, Bradycardia, AV conduction abnormalities, Cardiac arrest, Torsades, and Heart failure
Amiodarone route of admin?
IVP, IV infusion, IO
Amiodarone adult dose?
Vfib/pulseless Vtach:
300mg IV, IO; repeat 150mg IV,IO undiluted
Stable Vtach with a pulse:
150mg over 10 minutes (15mg/min)
Max cumulative dose of 2.2g in 24 hours
Amiodarone peds dose?
Refractory Vfib/pulseless Vtach:
5mg/kg IV, IO bolus; can be repeated to a total of 15mg/kg. Max single dose of 300mg
Perfusing SVT and ventricular dysrhythmias:
5mg/kg IV, IO over 20-60 minutes
Max cumulative dose of 2.2g in 24 hours
Amiodarone supply?
150mg/3mL ampules (50mg/mL)
Amiodarone special considerations?
Do not use with other drugs that cause prolonged QT interval (Procainamide)
