Abstract

Objective: To determine whether "early" ibuprofen treatment, at the onset of subtle patent ductus arteriosus (PDA) symptoms, would improve respiratory outcome in premature infants compared with "expectant" management, with ibuprofen treatment only when the PDA becomes hemodynamically significant (HS). Study design: We conducted a randomized double-blind controlled trial of infants with gestational ages 23 to 32 weeks and birth weights 500 to 1250 g who had echocardiography for subtle PDA symptoms (metabolic acidosis, murmur, bounding pulses). Infants were then randomized to "early" treatment (blinded ibuprofen; n = 54) or "expectant management" (blinded placebo, n = 51). If the PDA became HS (pulmonary hemorrhage, hypotension, respiratory deterioration), infants received open label ibuprofen. Infants with HS PDA at enrollment were excluded from the study. Respiratory outcomes and mortality and major morbidities were determined. Results: "Early" treatment infants received ibuprofen at median age of 3 days; infants in the "expectant group" in whom HS symptoms developed (20%) received ibuprofen at median of 11 days. A total of 49% of "expectant" infants never required ibuprofen or ligation. No significant differences were found in the primary outcome (days on oxygen [O 2] during the first 28 days), death, O 2 at 36 weeks, death or O 2 at 36 weeks, intestinal perforation, surgical necrotizing enterocolitis, grades III and IV intracranial hemorrhage, periventricular leukomalacia, sepsis or retinopathy of prematurity. Conclusion: Infants with mild signs of PDA do not benefit from early PDA treatment compared with delayed treatment.
