To determine whether oral paracetamol or ibuprofen has a better or same efficacy and tolerance in closure of patent ductus arteriosus in preterm infants.~Eighty preterm infants with patent ductus arteriosus will be enrolled in this prospective-randomized study. Patients will receive oral ibuprofen at an initial dose of 10 mg/kg, followed by 5 mg/kg at 24 and 48 h or oral paracetamol 15 mg/kg per dose every 6 hours.~One of the following echocardiographic criteria of a duct size >1.5 mm, a left atrium-to-aorta ratio >1.5, left-to-right shunting of blood, end diastolic reversal of blood flow in the aorta, or poor cardiac function in addition signs of patent ductus arteriosis determined the need of treatment.
The purpose of this study is to determine whether oral paracetamol or ibuprofen has a better or same efficacy and tolerance in closure of patent ductus arteriosus in preterm infants.
