Purpose: The survival rate of very low birth weight infants(VLBWI) has improved by advanced neonatal intensive care in level III hospital. We performed this study to evaluate the outcome including incidence, survival rate, mortality and morbidity of VLBWI and to get a help on more advanced care in neonatal intensive care unit(NICU).
Methods: The retrospective review of medical records was analysed for 205 VLBWI(＜1,500g) who were admitted to the NICU of Wonkwang University Hospital from January 2000 to December 2006.
Results: The incidence of VLBWI was 4.2%. Overall survival rate was 75.0% and which was lower than other hospital. By birth weight, survival rate was 92.6% in over 1,250g which was higher same as other large hospital, however it was 18.2% in below 750g which was lower than others. By gestational age, survival rate was higher over 80% in over 29 weeks, however which was lower 38.9% in 25-26 weeks and there is no lived in below 24 weeks. Common morbidities were respiratory distress syndrome(RDS) 75%, intraventricular hemorrhage 31.7%, patent ductus arteriosus 29.3%, retinopathy of prematurity 28.8% in the order of frequency. Most common time of death was within 3days 47.1%, and 70.6% died within 7 days. Major cause of death was RDS 23.5% within 3 days, pulmonary hemorrhage 9.8% in 4-7 days, and sepsis 16.7% in 8-27 days. Mean admission duration was 57.7±26.0 days.
Conclusion: Survival rate of VLBWI was much improved, but recently decreased a little. So, much efforts must be made with a skillful therapy and nursing care and to reduce a complications for increasing their survival rates.
