Renal-dose dopamine is associated with which clinical outcome?

Renal-dose dopamine is associated with which clinical outcome?

• A. It decreases renal perfusion
• B. Not effective for renal preservation
• C. It reliably preserves renal function
• D. It increases hepatic blood flow

Answer: (B)

Renal-dose dopamine was once thought to selectively boost kidney blood flow by acting on dopaminergic receptors in the renal vasculature, with the idea that this would help preserve kidney function in patients at risk for injury. But substantial clinical trials and reviews have shown no reliable benefit in preserving renal function, preventing acute kidney injury, or reducing the need for dialysis. In practice, this approach also exposes patients to potential harms such as increased heart rate, arrhythmias, and other adverse effects, without improving renal outcomes. So the best statement is that it is not effective for renal preservation.
