Detaljert beskrivelse
De primære målene med studien er å bekrefte sikkerheten til oral acetaminophen hos spedbarn med ekstremt lav fødsel, gitt samtidig med intravenøs ibuprofen, og også å bestemme effektiviteten til å øke graden av ductal lukking betydelig sammenlignet med kun intravenøs ibuprofen-behandling. Derfor inkluderer primær utfallsvariabel patent ductus arteriosus lukkingsgrad, basert på 2-D transthoracic ekkokardiografisk bevis.
Denne studien er en enkeltsenter, randomisert, dobbeltblindet, placebokontrollert studie. Premature spedbarn med svangerskapsalder med en svangerskapsalder ≤27 6/7 uker etter beste obstetriske estimat er kvalifisert for innmelding.
For randomisering vil studiepopulasjonen bli stratifisert til to undergrupper basert på svangerskapsalder (GA ≤24 uker og > 25 uker). Randomisering vil skje ved å bruke datamaskingenerert tilfeldig sekvens, ved bruk av en 4-blokk design, med 1:1 parallell allokering. Tildelinger inkluderer behandling og kontrollarm. Behandlingsarmen vil motta en kombinasjon av intravenøs ibuprofen og oral acetaminophen, mens kontrollarmen vil motta intravenøs ibuprofen og oral placebo.

Intervensjon / Behandling |
|---|---|
|
Eksperimentell: ibuprofen and acetaminophen arm (intervention arm)
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).

Aktiv komparator: ibuprofen and placebo arm (control arm)
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.
