为了探讨２０项新生儿行为神经测定（ＮＢＮＡ）在预报新生儿胆红素脑病中的意义，将２０项ＮＢＮＡ应用于６７例高胆红素血症患儿（足月儿），其中３３例同时测脑干听觉诱发电位（ＡＢＲ）。结果：（１）血清胆红素水平愈高，ＮＢＮＡ评分＜３５分者愈多；ＡＢＲ异常愈严重，ＮＢＮＡ评分＜３５分者也愈多。（２）黄疸消退后，６７例患儿的ＮＢＮＡ评分比黄疸高峰期普遍提高，差异有非常显著意义（Ｐ＜０．０１）。（３）黄疸高峰期１０例ＮＢＮＡ＜３５分者，黄疸消退后仍有５例ＮＢＮＡ＜３５分。ＮＢＮＡ≥３５分者，黄疸消退后ＮＢＮＡ均≥３７分。提示：ＮＢＮＡ能预报新生儿胆红素脑病，并能指导临床治疗，对ＮＢＮＡ＜３５分的患儿应采取积极有效的措施，甚至换血治疗，以防止核黄疸的发生。
To investigate the significance of 20 neonatal behavioral neurological tests (NBNA) in the prediction of neonatal bilirubin encephalopathy, 20 NBNAs were applied to 67 children with hyperbilirubinemia (term infants), of which 33 Brainstem auditory evoked potentials (ABR) were measured. Results: (1) The higher the level of serum bilirubin, the more NBNA score <35; the more serious abnormal ABR, the more NBNA score <35. (2) After jaundice subsided, the NBNA score of 67 children was generally higher than the peak of jaundice, the difference was significant (P <0.01). (3) In the peak of jaundice, 10 cases had NBNA <35 points, and 5 cases still had NBNA <35 points after jaundice subsided. NBNA ≥ 35 points, NBNA were ≥ 37 points after jaundice subsided. Tip: NBNA can predict neonatal bilirubin encephalopathy, and can guide the clinical treatment of NBNA <35 points in children should take positive and effective measures, and even exchange transfusion to prevent the occurrence of nuclear jaundice.
