Sepsis is a leading cause of neonatal morbidity and mortality. Clinical suspicion may lead to overuse antibiotics. The objective this study was assess the epidemiology early-onset sepsis (EOS) antibiotic exposure during first week life in Norwegian term infants.This nationwide population-based from Neonatal Network. During 3-year period (2009-2011), 20 Norway's 21 units prospectively collected data. Among 168,877 live-born (LB) infants born period, 10,175 (6.0%) were hospitalized included...

Group B streptococcus (GBS) is an important aetiological agent of serious neonatal infections. A rapid and sensitive method for the detection GBS colonization in pregnant women at delivery could make intrapartum screening possible. real-time PCR targeting sip gene has been evaluated. The performance was compared with optimized culture. Separate vaginal rectal swabs were collected from hospitalized department St Olavs Hospital, Trondheim, Norway, January 15 through May 2005. specimens...

Abstract Aim Neonatal jaundice is an important cause of morbidity and mortality, identifying the condition remains a challenge. This study evaluated novel method estimating bilirubin levels from colour‐calibrated smartphone images. Methods A cross‐sectional prospective was undertaken at two hospitals in Norway February 2017 to March 2019, with standardised illumination one hospital non‐standardised other hospital. Healthy term‐born infants normal birthweight were recruited up 15 days age....

Importance Preterm neonates are at risk for neurodevelopmental impairments, and there is a need to identify protective factors that can modify the harmful effects of preterm birth on immature brain. Objective To evaluate whether immediate skin-to-skin contact (SSC) improves early childhood outcomes. Design, Setting, Participants This open-label randomized clinical trial was conducted in 3 Norwegian neonatal units between February 2014 October 2020. were born 28 weeks 0 days’ 31 6 gestation...

Skin-to-skin care immediately following delivery is a common practice for term infants and has been shown to improve cardiorespiratory stability, facilitate early bonding, promote breastfeeding. Since 2007, the use of skin-to-skin practiced preterm from 32 weeks gestation in room at St. Olav's University Hospital. In present study we aim investigate whether safe, how it affects late outcomes compared standard very infants.

Abstract Aim We compared the pain relieving effect of skin‐to‐skin contact versus standard care in incubator during screening for retinopathy prematurity. Methods This randomised crossover study included 35 preterm infants less than 32 weeks gestational age admitted to St Olavs University Hospital, Trondheim, Norway, between January 2014 and June 2016. Randomisation was with one parents or supportive positioning by first two consecutive eye examinations. The score measured twice using...

There are various methods of respiratory support available to optimize function in preterm infants. Respiratory scoring tools might provide information on which method choose and the level duration needed. Before implementing a tool our clinical practice, we aimed test inter- intra-rater reliability Silverman Andersen index (SA index) among neonatologists nurses when applied infants support. We also examined association between SA electrical activity diaphragm (Edi signals).This was...
