Randomiseret kontrolleret forsøg for at evaluere sikkerheden og effektiviteten af ​​acetaminophen hos præmature spædbørn brugt i kombination med ibuprofen til lukning af ductus arteriosus

9. april 2026 opdateret af: Ramachandra Bhat, University of South Alabama

Enkeltcenter, randomiseret, dobbeltblindt, placebokontrolleret forsøg til evaluering af sikkerheden og effektiviteten af ​​acetaminophen hos præmature spædbørn brugt i kombination med ibuprofen til lukning af ductus arteriosus

Formålet med nærværende undersøgelse er at afgøre, om behandling af hæmodynamisk signifikant patent ductus arteriosus med en kombineret terapi af intravenøs Ibuprofen og oral acetaminophen har højere succesrate ved lukning af ductus arteriosus end en standardbehandlingsstrategi med anvendelse af intravenøs ibuprofen alene blandt præmature spædbørn.

Studieoversigt

Detaljeret beskrivelse

De primære mål med undersøgelsen er at bekræfte sikkerheden af ​​oral acetaminophen hos spædbørn med ekstremt lav fødsel, givet samtidig med intravenøs ibuprofen, og også at bestemme dets effektivitet med hensyn til signifikant at øge hastigheden af ​​ductal lukning sammenlignet med kun intravenøs ibuprofen-terapi. Derfor inkluderer den primære udfaldsvariabel patent ductus arteriosus lukning succesrate, baseret på 2-D transthorax ekkokardiografisk bevis.

Denne undersøgelse er et enkeltcenter, randomiseret, dobbeltblindet, placebokontrolleret forsøg. For tidligt fødte spædbørn med gestationsalder på med en gestationsalder ≤27 6/7 uger efter det bedste obstetriske skøn er berettiget til optagelse.

Til randomisering vil undersøgelsespopulationen blive stratificeret til to undergrupper baseret på gestationsalder (GA ≤24 uger og > 25 uger). Randomisering vil ske ved at bruge computergenereret tilfældig sekvens, ved hjælp af et 4-blok design, med 1:1 parallel allokering. Tildelinger inkluderer behandling og kontrolarm. Behandlingsarmen vil modtage en kombination af intravenøs ibuprofen og oral acetaminophen, mens kontrolarmen vil modtage intravenøs ibuprofen og oral placebo.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: 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).

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.
