Brief summary
In the present trial, early, intravenous paracetamol is compared to placebo in extremely premature or low birth weight infants in order to evaluate the effect on ductal closure.
Detailed description
The purpose of this randomized, placebo-controlled, double-blind, phase 2, one center clinical trial is to study the efficacy and safety of early (\< 96 h) intravenous paracetamol in prophylactic closure of ductus arteriosus in extremely premature (gestational age \<28+0 wk, ELGA) or low birth weight (\<1000 g, ELBW) infants. The infants born extremely preterm or low birth weight are a focus of the study, since a small phase 2 study on paracetamol failed to demonstrate contraction of ductus arteriosus. In the investigator's previous cohort of ELGA/ELBW infants, the numbers of patients who needed any therapies for patent ductus arteriosus (PDA) were 29 (23%) in the paracetamol exposed group, and 90 (54%) in the control group. As demonstrated in a phase 2 study, the early paracetamol treatment induced the closure of ductus arteriosus: the mean (SD) ductal closure age was 177 (338) h in the whole paracetamol group. However, in the subgroup of ELGA infants born before 28 gestation weeks (n=14), the mean (SD) ductal closure ages in the paracetamol and placebo groups were 491 (504) h and 858 (719) h, respectively.
Interventions
Intravenous paracetamol solution for infusion
Half physiological saline solution as the non-active placebo solution

Study design
Masking description
Placebo, 0.45 % saline, is similar to paracetamol, both being clear liquids, so the staff will remain unaware which drug the patient receives. The study drug will be kept and prepared away from the NICU, at the separate ward 55 office, in a locked cabinet. The study drug will be prepared by the research nurse, the pharmacist of the ward, or during nighttime, by a nurse who does not participate in the study patients' treatment in any way.
Intervention model description
Randomized, controlled, one center trial
