In a fetus with ductus-dependent systemic circulation, what treatment at birth is essential to maintain systemic perfusion?

In fetuses with ductus-dependent systemic circulation, the body’s blood flow to the systemic arteries relies on a patent ductus arteriosus after birth. If the ductus closes, systemic perfusion rapidly falls, leading to shock and organ hypoperfusion. The essential birth treatment is an infusion of prostaglandin E1 (alprostadil) to keep the ductus arteriosus open, preserving systemic blood flow while planning definitive management. NSAIDs would promote ductal closure and worsen perfusion, so they are not appropriate here. Observation or waiting won’t prevent ductal closure, and while surgical correction may be necessary, maintaining ductal patency with PGE1 is the crucial first step to stabilize the baby.
