An unusual peripheral vascular response to dopamine in a neonate.
We report a case of a neonate who developed hypotension immediately after birth, and needed dopamine infusion to sustain his blood pressure and tissue perfusion. He developed cyanosis of his extremity immediately after dopamine was started via peripheral line and improved spontaneously after dopamine was stopped. This happened repeatedly at various sites and at lower concentrations of dopamine. Subsequently, dopamine was replaced by dobutamine and the patient did well. We conclude that some neonates can show heightened alpha-adrenergic response to dopamine and this can lead to ischemic vascular events. Dopamine infusion in neonates should be started at a low-dose via central line.
