Characteristics and outcomes of respiratory distress among term infants born in a regional setting

Abstract

AbstractIntroductionRespiratory distress is the leading cause of admission to neonatal units and is a common indication for medical retrieval. Whilst approximately 25% of births in NSW occur in regional centres, there is a paucity of neonatal research in these settings.ObjectiveTo describe the characteristics and outcomes of term neonates admitted with respiratory distress to two regional special care nurseries (SCNs) and identify variables associated with the need for medical retrieval.DesignWe describe a cohort of 629 term infants admitted to the SCN in two regional hospitals, 2015–2019. We describe the admission characteristics, level of respiratory support, biochemical investigations, diagnosis and outcomes.FindingsDuring the study period, 629 eligible term infants were admitted, retrieval occurred in 29 (4.6%). Those admitted were more often male (66.5%), with a mean gestational age of 39 + 1 weeks (±9 days) and birth weight of 3470 g (±500 g). Infants requiring medical retrieval had higher PaCO2 on blood gas analysis (59.8 mmHg vs. 53.3 mmHg, OR 1.03, p = 0.02). There was no association between maternal GBS status, meconium‐stained liquor, gestational age, or raised inflammatory markers and medical retrieval. Transient tachypnoea of the newborn was the most common diagnosis of neonates admitted to SCN with respiratory distress.DiscussionAmong term infants admitted to a SCN for respiratory distress most were male, of a normal birthweight and born in good condition. Within our cohort there was no association between retrieval and maternal GBS colonisation, meconium‐stained liquor or raised infectious biomarkers. Medical retrieval was infrequent and was associated with higher PaCO2 on initial blood gas analysis.ConclusionWe present a large cohort of term newborn infants managed for respiratory distress in a regional setting over a five‐year period. Retrieval was infrequent, and outcomes for the cohort were excellent with no deaths during the study period.
