What is the primary treatment for intraoperative ventricular arrhythmias?

• A. Epinephrine
• B. Digitoxin
• C. Prostihmin
• D. Furosemide

Answer: (A)

The primary treatment for intraoperative ventricular arrhythmias is epinephrine. This medication is a potent vasopressor and sympathomimetic agent that increases heart rate and myocardial contractility, which can be essential in the management of significant arrhythmias. During surgical procedures, especially those involving the heart or significant fluid shifts, the balance of electrolytes and cardiac workload can be disrupted, leading to arrhythmias. Epinephrine acts quickly and can stabilize the cardiovascular system, making it a critical medication in this context. Other options listed do not primarily address the management of ventricular arrhythmias. For example, digitoxin is a cardiac glycoside that can be used to support cardiac function but is not specifically indicated for managing arrhythmias during surgery. Prostihmin, which is related to myasthenia gravis treatment, does not pertain to ventricular arrhythmias at all. Furosemide is a diuretic used to manage fluid overload but will not correct the underlying electrical disturbances that cause arrhythmias. Thus, the choice of epinephrine is centered on its effectiveness in acute emergency settings associated with arrhythmias.
