【摘要】 【目的】探讨足月低体重儿早期异常神经行为发育动态变化趋势,为早期干预介入提供依据。【方法】将106例足月低体重儿从1、2、4、6月分4个年龄段分别做52项神经行为检查,重点记录视听反应、头部控制、肌张力、神经反射及异常姿势的异常概率,并与同期出生的110例正常足月儿做比较。【结果】足月低体重儿早期神经行为异常主要集中在视听反应、头部控制、肌张力变化三方面,1、2、4月与正常组相比差异有显著性(P<0.05),随月龄增长至4月、6月,则以头部控制、肌张力、神经反射、异常姿势的异常为主,与正常组相比差异有显著性(P<0.05)。【结论】足月低体重儿早期神经行为异常表现随月龄增长有下降和变化趋势,早期定期追踪检查有助于把握干预时机,及时纠正异常的神经行为。更多还原

【Abstract】 【Objective】 To explore the early stage unordinary neurobehavioral development changeable trend in mature-low birth weight infants(MLBW),and give suggestion for early intervention. 【Methods】 106 MLBW were divided into four groups 1 month,2 months,4 months and 6 months according to their age.Each group was tested by 52 neurobehavior inspections.Control group included 110 cases of normal birth weight infants.In the experiments,it was focused on recording the unordinary ratio of their listening and looking reflection,head controlling,muscle tension,neuro-reflection and abnormal postures. 【Results】 During 1 month,2 months and 4 months,the ratio of unordinary neurobehavioral development such as listening and looking reflection,head controlling,muscle tension had significant difference from control group(P<0.05),while during 4 months,6 months,the unordinary ratio of MLBW head controlling,muscle tension and abnormal postures was higher than those in full-term normal delivery significantly(P<0.05). 【Conclusion】 Because the ratio of early unordinary neurobehaviors in MLBW have decline and change trend with their age increasing,it is beneficial to trace on time so as to hold the early stage intervention opportunities and correct unordinary neurobehaviors in time.更多还原
