Question: What perinatal factors influence patent ductus arteriosus (PDA) in and improve outcomes of preterm infants?
Finding: Lower birth weight, frequent surfactant treatment, and maternal hypertension increased hemodynamically significant PDA risk in very low birth weight infants, whereas chorioamnionitis and premature rupture of membranes protected against it. A lower birth weight and incomplete antenatal steroid use increased the risk of surgical ligation, whereas small for gestational age reduced it.
Meaning: Recognizing these factors may enable early, targeted intervention and reduce the need for surgical management.
