Adenosine is given intravenously, specifically as a rapid infusion for conditions like supraventricular tachycardia (SVT). Here's how it's typically administered:
Administration of Adenosine for SVT
Adenosine is a medication that helps to regulate heart rhythm. For treating SVT, a specific method of administration is essential for its effectiveness.
Step-by-Step Guide
- Intravenous Access: Establish a peripheral intravenous (IV) line. It's crucial to use a peripheral site for the best response.
- Dose: The initial dose of adenosine is typically 6 mg.
- Rapid Push: Administer the 6 mg dose quickly as an IV bolus.
- Saline Flush: Immediately follow the adenosine injection with a 20 mL saline flush. This helps to quickly move the medication into the bloodstream.
- Monitoring: Continuously monitor the patient's heart rhythm during and after administration.
Why is rapid infusion important?
Adenosine has a very short half-life (it's metabolized quickly by the body), therefore, a rapid administration is necessary to ensure the medication reaches the heart in a sufficient concentration. The saline flush further aids this process.
Practical Insights
- Preparation: Have the adenosine and saline flush ready before starting. This minimizes delays in administration.
- Patient Communication: Inform the patient that they may experience temporary side effects like chest tightness or flushing during the administration.
- Advanced Life Support: Be prepared for potential adverse reactions and have resuscitation equipment nearby.
