Study Arms:
- ibuprofen and acetaminophen arm (intervention arm) (Type: EXPERIMENTAL): ibuprofen and acetaminophen will be administered concomitantly. Ibuprofen will be administered through intravenous route. The dose of ibuprofen will be the standard dosing regimen used in our unit: dosing based on the postnatal age. For Infants \> 108 h of postnatal age: 18 mg/kg/dose loading dose followed by 9 mg/kg/dose, two doses at q24 intervals, started 24 h after the loading dose. Acetaminophen will be administered as oral formulation. Acetaminophen is given at a dose of 15 mg/Kg/dose, q 6 hours, for 3 days (total of 12 doses).
- ibuprofen and placebo arm (control arm) (Type: ACTIVE_COMPARATOR): ibuprofen and acetaminophen will be administered concomitantly. Ibuprofen will be administered through intravenous route. The dose of ibuprofen will be the standard dosing regimen used in our unit: dosing based on the postnatal age. For Infants \> 108 h of postnatal age: 18 mg/kg/dose loading dose followed by 9 mg/kg/dose, two doses at q24 intervals, started 24 h after the loading dose. Placebo will be sterile water, with similar volume and color as acetaminophen, will be given through the oro-gastric tube, for three days at 6 h intervals.

Based on this trial design, predict the completion outcome and termination type (if applicable).
