Several medications are commonly used in PALS, each serving a specific purpose: - Epinephrine: Used for its vasoconstrictive and cardiac stimulant properties, crucial in cases of cardiac arrest. - Amiodarone: An antiarrhythmic used for treating ventricular fibrillation and pulseless ventricular tachycardia. - Atropine: Administered for bradycardia to increase heart rate. - Adenosine: Used to treat supraventricular tachycardia by temporarily slowing down the heart rate. - Lidocaine: Another antiarrhythmic that can be used if amiodarone is not available.
