Questions: If myocardial function remains poor in a post-cardiac arrest child, what medication(s) should be considered? SELECT ALL THAT APPLY Dopamine Digoxin Epinephrine Milrinone Atropine

The medications that should be considered for a post-cardiac arrest child with poor myocardial function are:

• Dopamine: Dopamine is a positive inotropic agent that can help improve cardiac output by increasing heart contractility. It is often used in cases of poor myocardial function to support blood pressure and cardiac output.

• Epinephrine: Epinephrine is another inotropic agent that can increase heart rate and contractility, as well as cause vasoconstriction, which can help improve perfusion in a post-cardiac arrest scenario.

• Milrinone: Milrinone is a phosphodiesterase inhibitor that has inotropic and vasodilatory effects. It can improve cardiac output by increasing contractility and reducing afterload, making it useful in cases of poor myocardial function.

Explanation for each option:

• Dopamine: Correct. It is used to support cardiac output and blood pressure in cases of poor myocardial function.

• Digoxin: Incorrect. Digoxin is typically used for heart failure and atrial fibrillation but is not commonly used in acute post-cardiac arrest scenarios for improving myocardial function.

• Epinephrine: Correct. It is used in resuscitation and can improve myocardial function by increasing heart rate and contractility.

• Milrinone: Correct. It is beneficial for improving cardiac output and reducing afterload in cases of poor myocardial function.

• Atropine: Incorrect. Atropine is primarily used to treat bradycardia and does not have a direct role in improving myocardial contractility in post-cardiac arrest care.

In summary, the medications to consider for poor myocardial function in a post-cardiac arrest child are Dopamine, Epinephrine, and Milrinone.
