Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To explore if long term (> 72 hours) use of intravenous or oral paracetamol administered to neonates leads to risk of hepatotoxicity assessed by safety biomarkers, paracetamol metabolites (maturation pharmacokinetics) and accumulation of paracetamol. ; Secondary Objective: • To explore If ethanol containing drugs (phenobarbital) causes a measurable rise in p-ethanol and if the presence of ethanol change the pharmacokinetics of paracetamol in neonates • COMFORTneo pain scores ; Primary end point(s): Concentration-time data on plasma paracetamol, paracetamol-sulphate, paracetamol-glucuronide, oxidative metabolites and liver biomarkers (ALAT, PP, bilirubin) in neonates before, during and after multiple administrations of i.v. paracetamol with focus on long-term (>72 hours) treatment. Patients serve as their own control. ; Timepoint(s) of evaluation of this end point: The primary end points are evaluated at baseline, in steady state, when opportunistic blood sampling occurs and after end of treatment. | — |
Secondary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: P-ethanol will only be measured if the patient has received phenobarbital within 24 hours of blood-sampling. metabolites are measured as outlined in primary end points. COMFORT-neo pain scores is evaluated when p-paracetamol is measured in addition to clinical scores. ; Secondary end point(s): Levels of paracetamol metabolites and levels of p-ethanol in patients receiving one or more ethanol containing drugs compared to the patients not receiving ethanol containing drugs. COMFORT-neo pain scores. | — |
