Patent Ductus Arteriosus Management in Neonates

Introduction to PDA Management

• Early treatment of symptomatic PDA is recommended to prevent complications related to left-to-right shunting 2
• In very low birth weight (VLBW) infants, persistence of PDA is associated with significant morbidity and requires careful monitoring 1

Medical Management of PDA

• NSAIDs including indomethacin and ibuprofen should be avoided in the third trimester of pregnancy due to risk of premature ductal closure 3
• Surgical ligation is indicated when pharmacological treatment fails to close a symptomatic PDA 2
• In critically large PDAs that are refractory to medical management, surgical closure should be considered 4

Special Populations

• In VLBW infants, a more cautious approach to PDA management is recommended due to risk of intraventricular hemorrhage 5
• Persistence of PDA in VLBW infants is common due to immature ductal muscle being less able to constrict 5
• Rapid fluid administration may increase left-to-right shunting through the ductus with resultant pulmonary edema in VLBW infants 5

Treatment Approach

• Confirm hemodynamically significant PDA through echocardiography 2
• If first course of medical therapy fails, consider second course of medical therapy or surgical ligation for symptomatic infants unresponsive to medical therapy 4
