- AimWe aimed to describe clinical practices and criteria for discharge of very preterm infants in Nordic neonatal units.MethodsMedical directors of all 89 level-2 and level-3 units in Denmark, Finland, Iceland, Norway and Sweden were invited by e-mail to complete a web-based multiple-choice survey with the option to make additional free-text comments.ResultsWe received responses from 83/89 units (93%). In all responding units, discharge readiness was based mainly on clinical assessment with varying criteria. In addition, 36% used formal tests of cardiorespiratory stability and 59% used criteria related to infant weight or growth. For discharge with feeding tube, parental ability to speak the national language or English was mandatory in 45% of units, with large variation among countries. Post-discharge home visits and video-consultations were provided by 59% and 51%, respectively. In 54% of units, parental preparation for discharge were not initiated until the last two weeks of hospital stay.ConclusionDischarge readiness was based mainly on clinical assessment, with criteria varying among units despite similar population characteristics and care structures. This variation indicates a lack of evidence base and may unnecessarily delay discharge; further studies of this matter are needed. Earlier parental preparation and use of interpreters might facilitate earlier discharge.

- Background: Data on the cerebral effects of analgesic and sedative drugs are needed for the development of safe and effective treatments during neonatal intensive care. Electroencephalography (EEG) is an objective, but interpreter-dependent method for monitoring cortical activity. Quantitative computerized analyses might reveal EEG changes otherwise not detectable. Methods: EEG registrations were retrospectively collected from 21 infants (mean 38.7 gestational weeks; range 27–42) who received dexmedetomidine during neonatal care. The registrations were transformed into computational features and analyzed visually, and with two computational measures quantifying relative and absolute changes in power (range EEG; rEEG) and cortico-cortical synchrony (activation synchrony index; ASI), respectively. Results: The visual assessment did not reveal any drug effects. In rEEG analyses, a negative correlation was found between the baseline and the referential frontal (rho = 0.612, p = 0.006) and parietal (rho = −0.489, p = 0.035) derivations. The change in ASI was negatively correlated to baseline values in the interhemispheric (rho = −0.753; p = 0.001) and frontal comparisons (rho = −0.496; p = 0.038). Conclusion: Cerebral effects of dexmedetomidine as determined by EEG in newborn infants are related to cortical activity prior to DEX administration, indicating that higher brain activity levels (higher rEEG) during baseline links to a more pronounced reduction by DEX. The computational measurements indicate drug effects on both overall cortical activity and cortico-cortical communication. These effects were not evident in visual analysis.

- Aim: Organisation of care, perinatal and neonatal management of very preterm infants in the Nordic regions were hypothesised to vary significantly. The aim of this observational study was to test this hypothesis.Methods: Information on preterm infants in the 21 greater healthcare regions of Denmark, Finland, Iceland, Norway and Sweden was gathered from national registers in 2021. Preterm birth rates, case-mix, perinatal interventions, neonatal morbidity and survival to hospital discharge in very (<32 weeks) and extremely preterm infants (<28 weeks of gestational age) were compared.Results: Out of 287 642 infants born alive, 16 567 (5.8%) were preterm, 2389 (0.83%) very preterm and 800 (0.28%) were extremely preterm. In very preterm infants, exposure to antenatal corticosteroids varied from 85% to 98%, live births occurring at regional centres from 48% to 100%, surfactant treatment from 28% to 69% and use of mechanical ventilation varied from 13% to 77% (p < 0.05 for all comparisons). Significant regional variations within and between countries were also seen in capacity in neonatal care, case-mix and number of admissions, whereas there were no statistically significant differences in survival or major neonatal morbidities.Conclusion: Management of very preterm infants exhibited significant regional variations in the Nordic countries.

- BACKGROUND Extremely low gestational age newborns (ELGANs) are at risk of neurodevelopmental impairments that may originate in early NICU care. We hypothesized that early oxygen saturations (SpO(2)), arterial pO(2) levels, and supplemental oxygen (FiO(2)) would associate with later neuroanatomic changes.METHODS SpO(2), arterial blood gases, and FiO(2) from 73 ELGANs (GA 26.4 +/- 1.2; BW 867 +/- 179 g) during the first 3 postnatal days were correlated with later white matter injury (WM, MRI, n = 69), secondary cortical somatosensory processing in magnetoencephalography (MEG-SII, n = 39), Hempel neurological examination (n = 66), and developmental quotients of Griffiths Mental Developmental Scales (GMDS, n = 58).RESULTS The ELGANs with later WM abnormalities exhibited lower SpO(2) and pO(2) levels, and higher FiO(2) need during the first 3 days than those with normal WM. They also had higher pCO(2) values. The infants with abnormal MEG-SII showed opposite findings, i.e., displayed higher SpO(2) and pO(2) levels and lower FiO(2) need, than those with better outcomes. Severe WM changes and abnormal MEG-SII were correlated with adverse neurodevelopment.CONCLUSIONS Low oxygen levels and high FiO(2) need during the NICU care associate with WM abnormalities, whereas higher oxygen levels correlate with abnormal MEG-SII. The results may indicate certain brain structures being more vulnerable to hypoxia and others to hyperoxia, thus emphasizing the role of strict saturation targets. Impact This study indicates that both abnormally low and high oxygen levels during early NICU care are harmful for later neurodevelopmental outcomes in preterm neonates. Specific brain structures seem to be vulnerable to low and others to high oxygen levels. The findings may have clinical implications as oxygen is one of the most common therapies given in NICUs. The results emphasize the role of strict saturation targets during the early postnatal period in preterm infants.
