Adenosine (Adenocard) - Correct Answers Class: Antidysrhythmic
-----------------------------------------------------------
Indication: **Used for stable narrow complex SVT, or regular monomorphic wide-complex
tachycardia.**
Contraindication: 2nd or 3rd degree AV block, Sick Sinus Syndrome where you see the accessory
pathway conduct theatrial impulses at rates >220
----------------------------------------------------------
Pharm- Converts narrow complex regular tachycardia to normal sinus, works through slowing
conduction through AV node.
----------------------------------------------------------
Dosage:
Adult: 6mg RIVP followed immediately by NS flush
Wait 1-2 mins if no conversion then 2nd dose of 12 mg RIVP followed immed. by NS flush
Pedi: 0.1 mg/kg IVP (NTE 6 mg/dose)
2nd 0.2 mg/kg IVP (NTE 12 mg/dose)
----------------------------------------------------------
Action: Near Immediate, Peak 60 seconds, Duration 1-2 mins.
----------------------------------------------------------
Notes:
,If the patient's rhythm does not convert out of SVT within 1 - 2 minutes, a second 12 mg dose
may be given in a similar fashion. All efforts should be made to administer adenosine as quickly
as possible
Albuterol (Proventil, Ventolin) - Correct Answers Class: Bronchodilator
-----------------------------------------------------
Indication: Relief of bronchospasm in patients with reversible obstructive airway. Asthma, COPD,
Hyperkalemia.
-----------------------------------------------------
Contraindication: Cardiac Dys. associated with Tachycardia. Tachycardia caused by digitalis
intoxication.
-----------------------------------------------------
Pharm- Beta-2 adrenergic agonist, relaxes smooth muscles in the bronchi stimulates the
sympathetic nervous system. Also shifts potassium into intracellular space lowering serum
levels.
-----------------------------------------------------
Dosage:
Adult: 5mg Neb
Pedi:
<4: 2.5mg Neb
>4: 5mg Neb
—————————————————————————————
Action: Onset: 5-15 mins, Duration: 3-4 hours
Notes- can make diuertic induced hypokalemia worse and beta-blockers antagonize the effects
of Albuterol
, Amiodarone (Cordarone) - Correct Answers Class III Antidysrhythmic
(works in all 4 classes)
-----------------------------------------------------
Indication: V-fib, pulseless V-tac or pulsitile V-Tach. A-fib/SVT refractory to Adenosine/Diltiazem.
-----------------------------------------------------
Contraindications: Bradycardia, Cardiogenic Shock
----------------------------------------------------
Pharm- Prolongs action potential, non-competitive alpha and beta sympathetic blocking effects
and calcium-channel effects.
----------------------------------------------------
Dosage:
Adult:
V-Fib/pulseless V-Tac 300 mg in 50cc's of NS IVP
Repeat @ 150 mg IVP following ACLS algorithm.
Stable Pulsatile VTach- (Wide QRS greater than or equal to .12 per second. ) 150 mgs over 10
mins. Infusion should be 3mls of amiodarone (150mgs) in 100 mL D5W (concentration of 1.5
mg/ml) Infuse 100ml over 10 mins.
Pedi:
For pulsatile Vtach or stable SVT 5mgs/kg load over 20-60 mins. (max of 300 mgs). Repeat to
daily max of 15 mgs/kg.
Pulseless V-Tach/Vfib 5 mg/kg IVP Bolus IV/IO
repeat 5 mg/kg (NTE 300 mgs)
