Randomized Pilot Study Comparing Oral Ibuprofen With Intravenous Ibuprofen in Very Low Birth Weight Infants With Patent Ductus Arteriosus

We calculated that a study group of 62 patients would be necessary for the study to be able to detect a difference of at least 25 percentage points in the closure rate between the oral ibuprofen and intravenous ibuprofen groups, assuming a closure rate of 65 percent with intravenous ibuprofen, with a p value of 0, 05 and a power of 80 percent.Patients (gestational age, 25 to 32 weeks) with echocardiographically confirmed patent ductus arteriosus and respiratory distress will randomly be assigned to receive one (10 mg / kg), two (10 mg / kg followed 24 hours after by 5 mg /kg) or three (10 mg / kg followed at 24-hour intervals by two doses of 5 mg /kg each) doses of either intravenous ibuprofen (group I, n = 32) or oral ibuprofen (group O, n = 32), starting on the third day of life. The rate of ductal closure, side effects, complications, and the patients' clinical course will be recorded.
