Effect of oral ibuprofen on patent ductus arteriosus in premature newborns

ABSTRACT

Patent ductus arteriosus [PDA], a common finding among premature infants, is conventionally treated by intravenous indomethacin. Intravenous ibuprofen was recently shown to be as effective and to have fewer adverse reactions in preterm infants. If equally effective, then oral ibuprofen for PDA closure would have several important advantages over the intravenous route. This study was designed to determine whether oral ibuprofen treatment is efficacious and safe in closure of a PDA in premature infants. Thirty-three premature group I [study group] were treated with ibuprofen 10 mg/kg administered through a feeding tube. Thirty-three premature group II [control group] receive placebo the two imaging procedures were again performed 24h after each ibuprofen dose. When the PDA was still hemodynamically significant, as demonstrated by echocardiography, and there was no evidence of deterioration in brain ultrasonography, a second dose of ibuprofen 5mg/ kg [placebo for control] was administered. A third equivalent dose was given after another 24 h if necessary. Cranial ultrasound was repeated 1 week after the last ibuprofen dose and again before discharge from the ward. Hematochemical analysis was performed daily in the unit during the first days of life. In the study group the rate of PDA closure was 93.9% [31 of 33 case] while in the control group of the rate of PDA closure was 30.3% [10 of 33 cases] with significant difference in between. There was no reopening of the ductus after closure had been achieved. No infant required surgical ligation of the ductus in study group while in the control group 24.2% [8 of 33 cases] were required surgical ligation [Table 2]. Twenty- one newborns were treated with 1 dose of ibuprofen, 9 were treated with 2 doses, and the remaining 3 were treated with 3 doses. Oral ibuprofen is an effective and safe alternative to intravenous ibuprofen for PDA closure in premature infants
