The adenosine push video is a resource that provides information on the administration and use of adenosine in the treatment of narrow complex SVT (supraventricular tachycardia) due to reentry involving the AV or sinus node.

Adenosine is indicated for unstable narrow complex reentry tachycardia and should be given to the patient while preparing for cardioversion.

It is important to note that adenosine does not convert atrial fibrillation, atrial flutter, or ventricular tachycardia.

Precautions and contraindications include poison-induced and drug-induced tachycardia, as well as 2nd and 3rd degree heart blocks.

Adenosine is safe for use in pregnant patients but may be less effective in those taking theophylline or caffeine.

The medication is administered via rapid IV push, with an initial bolus of 6 mg over 1 to 3 seconds, followed by a normal saline bolus.

A second dose of 12 mg may be given if needed.

Adenosine acts on purinergic adenosine receptors to disrupt the resting membrane potential and slow conduction, bringing the patient out of SVT.

Continuous cardiac monitoring is recommended, and transient arrhythmias may occur following the initial period of asystole.

Side effects may include flushing, chest pain, asystole, bradycardia, and ventricular ectopy.

It is important to measure blood pressure before, during, and after adenosine therapy and to be aware of potential drug interactions.

Introduction to Adenosine as a Medication for SVT Termination

Adenosine is a medication that is used in the treatment of narrow complex supraventricular tachycardia (SVT) caused by reentry involving the AV or sinus node. SVT is an abnormal heart rhythm characterized by fast and irregular heartbeat. Adenosine interrupts the abnormal electrical pathways in the heart, effectively terminating the SVT and restoring a normal heart rhythm. This medication is essential in emergency situations where healthcare professionals need to promptly intervene and stabilize patients with SVT.

Indications and Usage of Adenosine in Various Types of Tachycardia

Adenosine: Focused and Informative

Adenosine is primarily indicated for the treatment of narrow complex SVT. It is also used in cases of unstable narrow complex reentry tachycardia, regular and monomorphic wide complex tachycardia, and as a diagnostic maneuver for stable narrow complex SVT. It is important to note that adenosine is not effective in converting atrial fibrillation, atrial flutter, or ventricular tachycardia. Thus, its use should be limited to the specific indications where it has been proven to be beneficial.

Precautions and Contraindications of Adenosine Administration

While adenosine is generally safe and well-tolerated, there are certain precautions and contraindications that healthcare professionals should be aware of. Adenosine should not be administered in cases of poison-induced tachycardia, drug-induced tachycardia, or patients with 2nd or 3rd degree heart blocks. Special caution should be exercised when prescribing adenosine to patients who are taking theophylline or caffeine, as it may be less effective in these individuals and could potentially lead to deterioration, including hypotension, if administered for irregular polymorphic wide complex tachycardia or ventricular tachycardia. It is crucial to assess each patient’s specific condition and medical history before initiating adenosine therapy.

Safety of Adenosine in Pregnant Patients:

One important aspect of adenosine’s safety profile is its use during pregnancy. Adenosine has been shown to be safe to administer to pregnant patients. However, as with any medication, close monitoring and individual assessment are necessary to ensure the well-being of both the mother and the unborn child.

Interaction with Theophylline and Caffeine, and Potential Deterioration in Irregular Polymorphic Wide Complex Tachycardia or V-Tach

Adenosine may interact with certain medications, notably theophylline and caffeine, which can reduce its effectiveness. Care should be taken in patients who are taking these medications, as they may require alternative treatment strategies for their tachycardia. In the case of irregular polymorphic wide complex tachycardia or ventricular tachycardia, adenosine is not recommended, as it can potentially worsen the condition and lead to hypotension. Healthcare professionals must consider these interactions and potential risks before administering adenosine to patients.

Common Side Effects of Adenosine

Like any medication, adenosine has associated side effects. The most common side effects include transient periods of flushing, chest pain, chest tightness, brief periods of asystole (temporary absence of heartbeat), brief periods of bradycardia (abnormally slow heart rate), and ventricular ectopy (extra heartbeats originating from the ventricles). These side effects are generally short-lived and resolve quickly after adenosine is administered. Patients should be informed of these potential side effects and reassured that they are typically not a cause for concern.

Recommended Initial Dose and Administration Procedure of Adenosine

To effectively terminate SVT, adenosine should be delivered via rapid intravenous (IV) push. The recommended initial dose of adenosine is 6 mg, administered over 1 to 3 seconds. Immediately following the adenosine push, a normal saline bolus of 20 ml should be administered. If necessary, a second dose of 12 mg may be given after 1 to 2 minutes. It is important to follow the specific dosing guidelines and administration procedure to ensure optimal efficacy and patient safety.

Mechanism of Action and Effectiveness of Adenosine in Terminating SVT

Adenosine is classified as a Class V antiarrhythmic drug and has a rapid onset of action. It acts on purinergic adenosine receptors, disrupting the resting membrane potential of the heart cells. This disruption leads to slower conduction, effectively terminating the abnormal heart rhythm associated with SVT. Adenosine’s short half-life of 10 seconds ensures that its effects are quickly reversible, making it a valuable tool in emergency situations.

Risks and Implications in Specific Patient Populations

While adenosine is generally well-tolerated, there are specific patient populations that require heightened caution. Patients with hypovolemia, valve stenosis, pericardial effusion, pericarditis, and autonomic neuropathy are at an increased risk of significant hypotension when administered adenosine. In these cases, alternative treatment options may need to be considered, and careful monitoring is essential to ensure patient safety.

Monitoring and Management During Adenosine Therapy

Continuous cardiac monitoring is essential for patients receiving adenosine therapy. Transient arrhythmias may occur after the initial asystole period, including premature ventricular contractions (PVCs), premature atrial contractions (PACs), sinus bradycardia, skipped beats, heart blocks, and sinus tachycardia. Therefore, it is crucial to closely monitor the patient’s cardiac rhythm and blood pressure before, during, and after adenosine administration. Prompt intervention may be necessary if any significant changes or complications arise.

In conclusion, adenosine is a life-saving medication used in the management of narrow complex SVT. Its use is indicated in specific types of tachycardia, and precautions should be taken in certain patient populations. Healthcare professionals should be aware of its mechanism of action, potential side effects, and the importance of close monitoring during administration. Adenosine plays a critical role in stabilizing patients with SVT, and proper utilization of this medication can greatly improve patient outcomes.

FAQ

What happens when you push adenosine?

When adenosine is pushed as a rapid intravenous bolus, it acts by causing a slowdown in cardiac conduction, specifically affecting the conduction through the AV node. Additionally, the rapid administration of adenosine can interrupt the reentry pathways in the AV node, providing a solution for patients with SVT. Through this intervention, sinus rhythm can be restored in individuals experiencing SVT instances. The administration of adenosine therefore plays a crucial role in alleviating cardiac conduction issues and bringing about a return to normal heart rhythm, notably for patients with SVT.

What does adenosine push feel like?

When administered, adenosine can elicit a range of sensations, some of which may be unsettling. Patients have described the adenosine push as an overwhelming surge, as if they were engulfed by a rapid wave of discomfort. They may experience an intense pounding sensation in their chest, accompanied by brief episodes of lightheadedness and a general sense of unease. While fleeting, these effects can be quite vivid, leaving patients with a feeling akin to being caught off guard by an unexpected blow to the chest.

How is adenosine pushed?

Adenosine is administered for the management of supraventricular tachycardia (SVT) through a peripheral intravenous (IV) access route. Initially, a 6 mg dose is pushed, accompanied by a 20 mL saline flush to facilitate quick infusion. For subsequent doses, the adenosine is delivered as 12 mg, followed by another 20 mL saline flush to ensure rapid administration. This approach ensures efficient delivery of the medication to counter SVT and facilitates prompt relief for patients.

What happens if you push adenosine slowly?

Pushing adenosine slowly can have unintended consequences. Instead of the desired rapid IV push, administering adenosine slowly may result in a brief period of bradycardia, asystole, or even third-degree heart block lasting for 10 to 15 seconds. These adverse effects can be unpredictable and potentially dangerous, highlighting the importance of following proper administration procedures and ensuring that adenosine is given rapidly to minimize these risks.
