Interhospital transport of sick newborn infants is dangerous, but the risk of adverse events can be reduced, when transport is being performed by trained neonatal retrieval teams. In this review, we describe the current organisation of neonatal retrieval service in Denmark. The services are based at the neonatal intensive care units of the four university hospitals.

Introduction: Anticipated or actual pain in neonates results in use of paracetamol for prolonged pain relief in many neonatal intensive care units. Clinical trials examining safety of paracetamol exposure in neonates have been of short duration (1-3 days) and hepatic biomarkers and paracetamol metabolism are rarely reported in the same studies.We aim to investigate the safety (hepatic tolerance) and effectiveness of prolonged paracetamol exposure in neonates by measuring hepatic biomarkers, plasma concentrations of paracetamol and its metabolites and pain scores.

Polymedicated neonates and young infants may be at risk of harmful cumulative exposure to toxic excipients like ethanol, propylene glycol and benzyl alcohol during routine clinical care. The aim of this study was to calculate the cumulative daily alcohol exposure (mg/kg/day) in polymedicated neonates and infants and compare these levels to the tolerance limits found in guidelines published by European Medicines Agency (EMA). As part of the SEEN study, all medicinal products administered to neonates and infants were recorded.

Introduction: The pharmacokinetics of excipients in neonates differs from that of older children. In a recent pan--European survey, two thirds of neonates received at least one potentially harmful excipient, such as ethanol and benzoates. The content of sweeteners varied by route of administration (more common by enteral than parenteral route), and regional differences were revealed.

Aim: To examine concentrations of three cardiovascular propeptides in umbilical cord plasma of neonates born to mothers with Type 1, Type 2 and gestational diabetes. Measurement of cardiovascular markers in umbilical cord plasma may potentially help identify neonates at risk of postnatal complications. Neonates born to mothers with diabetes have an increased risk of neonatal morbidity and mortality, and measurement of these new biomarkers may potentially help identify neonates at risk of these complications.

This case presents a thirteen months old child with severe acute respiratory distress syndrome after ingestion of lamp oil (hydrocarbon). Mechanical ventilation including high-frequency oscillation could not stabilise the course, and the child developed pneumothorax and emphysema. Treatment was changed to veno-arterial extracorporeal membrane oxygenation (ECMO) on the third day.

Objective: To evaluate OK-432, a preparation of Streptococcus pyogenes, in the treatment of early fetal chylothorax.

Methods: A prospective study of all fetuses (n=7) with persistent early chylothorax (gestational ages 16-21 weeks) referred to the tertiary center of fetal medicine in Denmark in 2003-2005. Fetuses were injected with 0.
