Abstract
We investigated the effects of dopamine on pulmonary artery pressure in 18 ventilated hypotensive preterm neonates by using the flow characteristics of the ductal shunt. Dopamine has variable effects on pulmonary/systemic mean arterial pressure ratio with half the neonates showing an increase in pulmonary pressure relative to systemic pressure.
