Dopamine Receptor Effects by Dose
1–3 mcg/kg/min Dopaminergic (DA1/DA2): Renal & splanchnic vasodilation — clinical benefit controversial
3–10 mcg/kg/min Beta-1: ↑HR, ↑contractility, ↑cardiac output
10–20 mcg/kg/min Alpha-1: Vasoconstriction, ↑SVR, ↑blood pressure
>20 mcg/kg/min Predominantly Alpha: High ischemia risk, avoid if possible
⚠ Clinical Guidance: Norepinephrine is preferred over dopamine for septic shock (SOAP-II trial — dopamine associated with higher arrhythmia rates and 28-day mortality in cardiogenic shock subgroup). Dopamine may be considered in bradycardic shock. Continuous ECG monitoring required.
