Admission of Term Infants to Neonatal Intensive Care Unit from Nursery / 대한주산의학회잡지

ABSTRACT

PURPOSE: We evaluated the clinical characteristics of term infants admitted to the neonatal intensive care unit (NICU) from nursery. METHODS: This is a study of NICU-admitted infants who were born > or =37 weeks of gestation at the Bungdang CHA Hospital between January 2012 and August 2013 (n=161). The infants were divided into 3 groups. The "nursery room (NR) group" (n=97) comprised admissions from the nursery following a late deterioration in condition. The "delivery room (DR) group" (n=64) comprised infants who required admission to the NICU immediately after delivery. In addition, healthy term infants who were selected as the "Term group" (n=95). RESULTS: The NR group had a higher incidence of respiratory distress syndrome than DR group (28.9% vs. 14.1%, P=0.029). Compared with the Term group, the NR group had increased incidence of prolonged (>18 h) premature rupture of membranes (PROM) (6.2% vs. 0.0%, P=0.029). By logistic regression analysis, comparing NR group and Term group, a 1 min Apgar score < or =7 points {odds ratio (OR) and 95% confidence intervals (CI) 3.1 (1.0-9.1)}, a requirement of O2 at birth 2.6 (1.2-5.9) and abnormalities detected on an antenatal sonogram 3.3 (1.4-7.8) were associated with an increased risk of admission to NICU. CONCLUSION: Risk factors for NICU admission from nursery in term infants included prolonged PROM, a 1 min Apgar score of < or =7 points, a requirement of O2 at birth, and abnormalities on antenatal sonograms. Term infants with these risk factors should be carefully observed in the early neonatal period.
