  1. Adenosine
       Classification
    Antidysrhythmic Agent
  2. Adenosine
       Action
    • -Suppresses AV conduction
    • -Terminates supraventricular dysrhythmias
    • -Depresses automaticity in the sinus node
  3. Adenosine
       Indications
    • Perfusing SVT unresponsive to valsalva
    • Poorly perfusing SVT in a conscious patient
  4. Adenosine
       Contraindications
    • -History of Sick Sinus Syndrome
    • -2/3 degree heart blocks
    • -Pts known to be taking:
    •      Persantine (dipyridamole)
    •      Tegretol (carbamazepine)
  5. Adenosine
       Adverse Effects
    • Cardiovascular
    • Chest pain/pressure
    • Hypotension
    • Bradycardia/Asystole
    • 2/3 degree blocks
    • PAC's/PVC's

    • Neurological
    • Headache
    • Dizziness
    • Seizures
    • Numbness
    • Tingling
    • Blurred Vision

    • Respiratory
    • Dyspnea/SOB
    • Bronchoconstriction in asthmatic pts
  6. Adenosine
       Administration
    • 6mg rapid IV/IO w/in 1-3 secs
    • Follow w/ rapid flush of 10-20ml NS
    • May rpt 12 mg in 1-2 mins (2x)
  7. Adenosine
       Pediatrics
    • 0.1mg/kg rapid IV/IO, w/in 1-3 secs
    • Follow w/rapid flush of 10ml NS
  8. Adenosine
       Onset
       Duration
    • Onset
    • Immediate

    • Duration
    • <10secs
  9. Adenosine
       Precautions
    Because of short duration, to ensure rapid admin into central circulation

    Cannulate a lg vein (antecubital fossa) using an 18-20g catheter

    Use IV port closest to pt and immediately flush w/10-20ml NS
  10. Adenosine
       Note
    Monitor pt continually and run 6 sec strip before, during and after administration

    Adverse effects of chest pain/pressure, numbness/tingling or SOB will resolve w/in 1-2 mins

    Persantine and Tegretol potentiate the actions of adenosine which may result in 2/3rd degree heart blocks

    Adenosine will not convert sinus tach, A-flutter or A-fib to a normal sinus rhythm, but may cause transient slowing of the heart rate in A-fib w/a rapid ventricular response

    Theophylline and Xanthing preparations may render adenosine ineffective
