On the other hand, tThe neurological development and growth of extremely preterm infants have come to be the emerging issue in the next stage of following the management of in NICU.
Objective: To assess potential associations between changes in practice and survival/neurodevelopmental outcome, and clinical outcomes of extremely preterm infants born at the limit of viability were studied in a tertiary center.　　
Study design: A retrospective study enrolled 51 infants who had no congenital disorders, and were born at 22-24 weeks of gestational age (GA) in 2000-2009 in our single institution. Clinical variables and interventions were studied with regard to one-year survival and developmental quotient (DQ) at 3 years of age.　　
Results: The one-year survival rate of 24 preterm infants born in 2005-2009 (79%) was higher than that of the 27 those infants born in 2000-2004 (52%) (p=0.04). The iInfants born at or post-2005 underwent less and more frequently tocolysis (54% vs. 94%, p<0.01) and more frequently antenatal steroid therapy (32% vs. 6%, p=0.01) than those born at pre-20045, respectively. The post-2005 survivors (n=19) received more frequently indomethacin therapy (89% vs. 50%, p=0.03) and early parenteral nutrition (95% vs. 36%, p<0.01) than the pre-20045 survivors (n=14). There were no differences in the proportion of infants who attained a DQ of >50 at 3-years of age between pre-20045 (n=9/13=69%) and post-2005 groups (n=10/17=59%) (30% vs. 33%). Multivariate analysis indicated that extremely premature birth ity born at GA<24w was the sole critical factor for the development status with the a DQ of >50 in survivors.　　
Conclusions: The perinatal care after 2005 could improved the overall survival rate, but not, the neurological outcomes of preterm survivors at the limit of viability. Neurodevelopmental impairments were associated with the extremely premature birth ity born at GA<24w.
