本文总结了1994年10月～1995年5月,对150例围产期高危儿利用NBNA即20项神经行为评分法检查脑损伤发生情况,结果在150例高危儿中发现行为异常(低分值)96例,发生率为64％,比对照组(3％)明显高(P<0.01).对NBNA低分者进行头颅B超检查,共发现HIE90例,NBNA诊HIE与头颅B超诊所HIE的符合率为94％。且NBNA评分越低,HIE越重。影响NBNA低分值的高危因素中以宫内窘迫,重度窒息及妊高征等关系密切,对行为异常者全部给予干预措施,并在6月～1年后随访,显示干预的效果良好,说明NBNA方法实用、经济、可靠、灵敏性高,应值得推广。
This article summarizes the 1994 October to 1995 May, 150 perinatal high-risk children using NBNA that is 20 neurobehavioral scoring method to examine the occurrence of brain injury, the result was found in 150 cases of high-risk infants (low score ) 96 cases, the incidence was 64%, which was significantly higher than that of the control group (3%) (P <0.01) .BNA ultrasonography was performed on the low score of NBNA, found 90 cases of HIE, NBNA diagnosis of HIE and B ultrasound clinic HIE The coincidence rate was 94%. The lower the NBNA score, the heavier the HIE. Among the risk factors that affect the low score of NBNA, the patients with intrauterine distress, severe asphyxia and pregnancy-induced hypertension are closely related, and all the patients with abnormal behavior are given interventions and follow-up from June to January, which shows the effect of intervention is good The NBNA method is practical, economical, reliable and highly sensitive and deserves promotion.
