Aim: We aimed to describe clinical practices and criteria for discharge of very preterm infants in Nordic neonatal units. Methods: Medical 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. Results: We 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. Conclusion: Discharge 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. [ABSTRACT FROM AUTHOR]

Aim: The first dedicated neonatal continuous positive airway pressure (CPAP) device using variable flow was the Infant Flow. The system was pressure stable with a low resistance to breathing. The aim of this study was to describe the flow and function of the Infant Flow geometry using simulated breathing and computational fluid dynamics. Method: The original Infant Flow geometry was used with simulated term infant breathing at three levels of CPAP. The large eddy simulation methodology was applied in combination with the WALE sub‐grid scale model. Results: The simulation fully resolved the flow phenomena in the Infant Flow geometry. The main flow feature during inspiration was support by gas entrainment and mixing. During expiration, the jet deflected towards the outlet with unstable impingement of the jet at the opposing edge. Conclusion: The proposed mechanism has previously been based on theoretical reasoning, and our results present the first detailed description of the Infant Flow. The pressure stability was based on a jet supporting inspiration by gas entrainment and then being deflected during exhalation. This confirmed previously assumed principles of function and flows within the geometry and provided a base for further developments. [ABSTRACT FROM AUTHOR]

Aim: This study evaluated if oral supplementation with the probiotic bacterium Lactobacillus reuteri DSM 17938 improved enteral feeding tolerance and growth rates in extremely low birthweight (ELBW) infants.Method: A randomised, double-blind, placebo-controlled trial comprising 134 ELBW (<1000 g) infants born before gestational week 28 + 0. Daily supplementation of L. reuteri (1.25 × 108 bacteria/day) or placebo started within 3 days and continued until gestational week 36 + 0. Primary outcome was feeding tolerance and secondary outcome growth rate calculated as z-score development.Results: Feeding tolerance was similar in the probiotic and placebo group. Time to full enteral feeds was 15 days in both groups. The z-score of the head circumference decreased in both groups from birth to day 28 of life, but it decreased less in the L. reuteri group compared to the placebo group: -1.2 SD (95% CI: -1.4 to -1.0) versus -1.7 SD (95% CI: -2.0 to -1.5; p = 0.001). Other growth parameters were similar in the study groups.Conclusion: Lactobacillus reuteri did not reduce time to reach full enteral feeds in ELBW infants. The L. reuteri supplemented infants, however, had a better growth rate of the head during the first month of life. [ABSTRACT FROM AUTHOR]
