Adenosine capacitación - video

Now let’s cover Adenosine.

Adenosine is effective in terminating narrow complex SVT due to reentry involving AV or

Sinus node.

It’s used for unstable narrow-complex reentry tachycardia and it should be given while preparing

to cardiovert.

It’s important to note that Adenosine does not convert atrial fibrillation, atrial flutter

or ventricular Tachycardia known as V-tach.

Adenosine is indicated for: narrow-complex supraventricular tachycardia or SVT, unstable

narrow-complex reentry tachycardia, regular and monomorphic wide-complex tachycardia,

or as a diagnostic maneuver for stable narrow-complex SVT.

Adenosine is contraindicated in poison/drug induced tachycardia or second or third-degree

heart blocks.

Now it is safe during pregnancy.

It is less effective in patients taking theophylline or caffeine and if administered for irregular

polymorphic wide-complex tachycardia or VTach, it could cause deterioration including hypotension.

Its side effects include transient periods of flushing, chest pain or tightness, brief

periods of asystole or bradycardia, and ventricular ectopy.

Reduce the initial dose to 3 mg in patients receiving dipyridamole or carbamazepine,

in heart transplant patients or if given by central venous access, remember that transient

periods of sinus bradycardia and ventricular ectopy are common after termination of SVT.

This medication should be delivered IV, Rapid Push.

First, place the patient in a moderate reverse Trendelenburg position before administration

of the drug.

The initial bolus of 6mg is given rapidly over 1 to 3 seconds followed by a normal saline

bolus of 20ml.

It’s recommended that the extremity in which the drug was administered be elevated.

A second dose of 12mg can be given in 1 to 2 minutes if needed.

Now, while we’re doing this, make sure to record a rhythm strip during administration.

Draw up the adenosine dose and saline flush in 2 separate syringes.

Attach both syringes to the IV injection port closest to the patient.

Clamp the IV tubing above the injection port, then Push IV adenosine as quickly as possible.

While maintaining pressure on adenosine plunger, push the normal saline flush as rapidly as

possible after the adenosine.

Unclamp IV tubing and monitor the outcome.
