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.
