Abstract

Objective To investigate changes of neurodevelopmental outcomes of very low birth weight infant (VLBWI) and extremely birth weight infant (ELBWI) occurred over the recent years. Methods The population included 143 VLBWI and ELBWI admitted from October 1^st 2005 to December 31^st 2010 who had finished the infant development test of BSID-Ⅱ at corrected gestational aged 18~42 months.The neurodevelopmental outcomes between two periods[2005-2008 (period 1);2009-2010 (period 2)]were compared. Results The subjects in two-period study were similar in gender, gestational age, and birth weight.The neurodevelopmental outcomes in period 2 improved:the MDI score was increased (97.0±14.6) versus (88.6±19.2)(P=0.004), and the rate of MDI<70 was decreased (3.4% versus 14.8%, P=0.014).In the period 1, the incidence of neurodevelopmental impairment and cerebral palsy were higher than the period 2 (22.2% versus 13.5%, 9.3% versus 2.3%), and the PDI score was lower[(83.6±16.1) versus (85.0±13.6)]and the rate of PDI<70 was higher (16.7% versus 12.4%).But these differences were not statistically significant. Conclusions Recent years, the neurodevelopmental outcomes of VLBWI and ELBWI seem to improve.Both doctors and parents should pay attention to the follow-up and early intervention of VLBWI and ELBWI after discharge, by which to improve their neurodevelopmental outcomes.
