Between January 1 , 2003and June 30 , 2005 224 infants with birthweights less than 1251 g were admitted to UICH NICU by birth or transfer at less than 24 hours' age.
Of these, 1,010 newborns weighing 500 1499 g were admitted to neonatal units (4% of births) and 383 were excluded: 75 with congenital malformations, 21 deaths in the delivery room, 24 with gestational age ≥37 weeks, 10 with gestational age <23 weeks and 253 with gestational age 32-366/7 weeks.
According to our internal clinical protocol, late preterm infants with a birth weight ≥1900 g, irrespective of gestational age, were admitted to level I of care, provided that clinical conditions were stable and no nutritional support was required.
Study Design: A total of 1283 infants weighing <1500 g who were admitted to six neonatal intensive care units over 21 months were analyzed prospectively.
Objectives and study design: To evaluate the morbidity and mortality of preterm infants with congenital heart disease (CHD), a chart review was performed for infants with CHD, excluding isolated patent ductus arteriosus, who were <37 weeks' gestation, weighed <2500 g, and were admitted to our neonatal intensive care unit from 1976 to 1999 (N = 201).
As a consequence, there was a 60% reduction in the number of hospital admissions due to infection (relative risk 0.40, P=0.006) and if a patient on G-CSF were admitted they spent about half the time in hospital (ratio of the mean hospital stay 0.53).
Preterm infants born at <33 wk of gestational age or with a birth weight of <1,500 g and who were admitted to the neonatal intensive care unit (NICU) at the University of Fukui Hospital between April 2011 and January 2014 were enrolled in this study.
At birth, the 3 live-born infants were at 27, 32, and 37 weeks' gestation and weighed 824, 1,850, and 3,270 g, respectively; all were admitted to a neonatal ICU.
120 patients with birth weight less than 1500 g per year were admitted to the NICU with a survival rate of 90%, bronchopulmonary dysplasia (BPD) rate at 36 weeks of 16.4%, and a rate for retinopathy of prematurity (ROP) grade 3 or higher of 1.4%.
A total of 81.8 % of the infants had birth weights less than 2,500 g; moreover, 45.5 % were admitted to public NICU, and 54.5 % were admitted to private NICU.
Among the babies, 4.3% had a low birth weight (under 2500 g) and 12.3% were admitted to the neonatology unit for different medical reasons not examined here.
