晚期早产儿早期智能发育结局的研究

目的探讨晚期早产儿(LPI)早期智能发育结局。方法选择2012年1月至2015年1月新生儿病房收治的出生胎龄34~36+6周、治愈出院并定期规律随访的106例早产儿为晚期早产儿组;随机抽取同期120例健康足月儿(FPI)为对照组。对校正年龄40周的晚期早产儿及40周龄的足月儿进行新生儿神经行为测定(NBNA),晚期早产儿校正龄3、6、12月龄或者足月儿3、6、12月龄时采用Gesell发育量表进行评估。结果 LPI组NBNA评分低于37分,低于FTI组(P0.05)。校正龄3月龄时,LPI组大运动、精细运动、个人社交落后于FTI组(P0.05);校正龄6月龄时,LPI组适应性、大运动、精细运动落后于FTI组(P0.05);校正年龄12月龄时,LPI组适应性、大运动、个人社交测评明显低于FTI组(P0.05)。结论晚期早产儿早期智能发育迟缓,需加强神经发育监测。

Early intellectual developmental outcome of late preterm infants

ObjectiveTo investigate the early intellectual developmental outcome of late preterm infants. MethodsA total of 106 late preterm infants with a gestational age of 34-36+6 weeks who were admitted to the neonatal ward between January 2012 and January 2015, cured, discharged, and regularly followed up at the outpatient service for high-risk children were enrolled as the preterm group. A total of 120 healthy full-term infants during the same period were randomly selected as the term group. Neonatal behavioral neurological assessment (NBNA) was performed for late preterm infants at a corrected gestational age of 40 weeks and full-term infants at a gestational age of 40 weeks. The Gesell Developmental Scale was used for late preterm infants at a corrected age of 3, 6, and 12 months and full-term infants at an age of 3, 6, and 12 months.ResultsThe preterm group had an NBNA score of<37 and a signiifcantly lower NBNA score than the term group (P<0.05). At the corrected age of 3 months, the preterm group had signiifcantly lower scores of gross motor, ifne motor, and social competence than the term group (P<0.05). At the corrected age of 6 months, the preterm group had signiifcantly lower scores of adaptability, gross motor, and fine motor than the term group(P<0.05). At the corrected age of 12 months, the preterm group had significantly lower scores of adaptability, gross motor, and social competence than the term group (P<0.05).ConclusionsLate preterm infants have early intellectual developmental delay. It is necessary to perform neurodevelopmental monitoring for late preterm infants.
