| Abstract |
Purpose
The survival rate of very low birth weight infant (VLBWI) had increased as a result of advances in neonatal intensive
care. We evaluated the changes in outcomes of VLBWI who admitted to the neonatal care unit of Hallym University Kangnam
Sacred Heart Hospital.
Methods
Retrospective review of 339 VLBWI who were born from 1st January 1997 to 31th December 2008 were performed.
Outcomes including survival rate, birth weight (BW), gestational age (GA), morbidities, and mortality between period I (1997-
2003) and period II (2004-2008) were compared.
Results
Overall incidence of VLBWI was 2.3% and it was significantly higher in period II(3.3%). Mean BW and GA were
significantly decreased in period II (P<0.001, P=0.01). The survival rate increased from period I (59.1%) to period II (74.2%).
BW-specific survival rate increased in 1,000-1,249 gm and GA-specific survival rate significantly increased in 27-28 weeks and
29-30 weeks. The incidences of respiratory distress syndrome (RDS), retinopathy of prematurity (ROP), sepsis, bronchopulmonary
dysplasia (BPD), intraventricular hemorrhage, periventricular leukomalacia, and necorotizing enterocolitis were same except
patent ductus arteriosus.
Conclusion
The survival rate of VLBWI was increased in period II, especially in less than 1,000 gm and below 27 weeks. This
may be due to recent dramatic improvement of neonatal care. But more efforts are needed to improve outcome during initial
phase and to reduce long term complication such as BPD and ROP. |
