Study Notes
Emergency Drugs
- Emergency drugs are medications used to treat life-threatening conditions or symptoms, such as cardiac arrest, respiratory distress, or allergic reactions.
Adenosine (Adenocard)
- Mechanism of action: Slows down the heart rate by blocking the AV node, allowing the heart to return to a normal rhythm.
Amiodarone
- Indications: Treatment of life-threatening ventricular fibrillation, pulseless ventricular tachycardia, and atrial fibrillation.
Adenosine Dosing
- Maximum recommended single dose for supraventricular tachycardia: 6-12mg by rapid IV push, repeated every 1-2 minutes as needed.
Adenosine Administration
- After administering Adenosine, nurses should:
- Monitor the patient's heart rate and rhythm continuously for at least 30 minutes.
- Be prepared to provide emergency treatment, such as CPR, if the patient's heart rate becomes too slow or irregular.
