Question

Quizplus · Accepted Answer

Dopamine is a medication that acts on the sympathetic nervous system to increase heart rate and contractility, as well as dilate blood vessels. It is commonly used in the early postoperative period after heart transplant to support cardiac function and circulation while the new heart adapts to its new surroundings. Low doses of dopamine can help maintain stable blood pressure and perfusion to vital organs, while higher doses can cause undesired side effects. Enalapril is an ACE inhibitor commonly used to treat hypertension, but it is not typically used in postoperative management of heart transplant patients. Digoxin is a medication used to improve heart function in chronic heart failure, but it is not often used in the acute setting after heart transplant. Anginine (nitroglycerin) is typically used to treat angina and may be used in a heart transplant patient if they develop chest pain or angina-like symptoms, but it is not specifically used to support cardiac function and circulation in the early postoperative period.
