Patent Ductus Arteriosus (PDA) Screening Trial
The Role of Serial Echocardiography to Detect an Asymptomatic Patent Ductus Arteriosus (PDA) in Very Low Birth Weight (VLBW) Infants: A Pilot Randomized Controlled Trial
The ductus arteriosus directs blood away from the pulmonary circulation and toward the systemic circulation during fetal life, then closes after birth. In preterm infants the incidence of spontaneous closure decreases with gestational age. Patent ductus arteriosus (PDA) increases the risks of bronchopulmonary dysplasia (BPD) and necrotizing enterocolitis (NEC). However, this association may not be a causal relationship.
Echocardiography is required to diagnose PDA. However, routine screening echocardiograms lead to detection of asymptomatic PDAs, for which the benefit of therapy remains unproven.
A randomized controlled trial has been designed in which 88 infants with birth weight less than or equal to 1250 grams and gestational age less than or equal to 30 weeks will be enrolled. The investigators' goal is to determine how screening echocardiography influences clinical management and outcomes in these infants.
