Study Notes
Emergency Drugs
- Emergency drugs are used to treat life-threatening conditions, such as cardiac arrest, and are usually administered rapidly to restore cardiac function and circulation.
Adenosine (Adenocard)
- Adenosine slows down the heart rate by blocking the electrical pathway in the heart.
- It works by stimulating the vagus nerve, which slows down the heart rate.
- Maximum single dose: 12mg.
Amiodarone
- Amiodarone is used to treat ventricular fibrillation and pulseless ventricular tachycardia.
- It slows down the heart rate and helps the heart beat more normally.
- Side effects: corneal microdeposits, pulmonary toxicity, and thyroid dysfunction.
- Administration: Amiodarone infusion should be administered via a central line, and nurses should monitor the patient's ECG and vital signs closely during the infusion.
